Can two species share the same niche? Why or why not?​

Answers

Answer 1

Answer:

No

Explanation:

Because they'd be fighting for the exact same resources

Answer 2

Answer:

The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

Answer:

It is a Soil Creep.

Explanation:

If it is not, sorry.

The continuous downward movement of soil or regolith (loose rock and silt) is called soil creep or solifluction. Therefore, the correct option is B.

This occurs as a result of repeated freeze-thaw cycles or wet-dry cycles that cause expansion and contraction of soil particles. On gentle slopes, soil sliding is often observed, and is characterized by the slow, steady descent of soil particles over time.

Individual soil particles are lifted up, obliterated, and then gravity pulls them downward during the process of soil creep. By bending trees or fences, or by creating terraces—small, stair-like features on the surface of a slope, this slow movement can produce stunning effects.

Therefore, the correct option is B

III. Describe two or more environmental problems and tell what can be done to help
solve them. First write and then record five sentences. (in spanish)

Answers

Two environmental problems are climate change and deforestation. Climate change is caused by the increase in greenhouse gases, primarily carbon dioxide, in the atmosphere which traps heat and leads to global warming. Deforestation is the removal of trees from a forested area for agricultural or commercial purposes, leading to loss of habitat and increased greenhouse gases.

To help solve climate change, reducing carbon emissions is crucial. This can be done through switching to renewable energy sources like wind or solar power, using more energy-efficient appliances, and reducing meat consumption. Also, planting more trees can help absorb carbon dioxide from the atmosphere.

To help solve deforestation, using sustainable practices in agriculture and logging can help reduce the destruction of forests. This includes replanting trees and implementing sustainable logging techniques that do not harm the environment. Supporting companies that use sustainable and eco-friendly practices can also encourage more responsible behavior.

Dos problemas ambientales son el cambio climático y la deforestación. El cambio climático es causado por el aumento de los gases de efecto invernadero, principalmente dióxido de carbono, en la atmósfera que atrapa el calor y conduce al calentamiento global. La deforestación es la eliminación de árboles de un área boscosa con fines agrícolas o comerciales, lo que lleva a la pérdida de hábitat y al aumento de los gases de efecto invernadero.

Para ayudar a resolver el cambio climático, la reducción de las emisiones de carbono es crucial. Esto se puede hacer mediante el cambio a fuentes de energía renovables como la energía eólica o solar, el uso de electrodomésticos más eficientes y la reducción del consumo de carne. Además, plantar más árboles puede ayudar a absorber el dióxido de carbono de la atmósfera.

Para ayudar a resolver la deforestación, el uso de prácticas sostenibles en la agricultura y la tala puede ayudar a reducir la destrucción de los bosques. Esto incluye replantar árboles e implementar técnicas de tala sostenible que no dañen el medio ambiente.

How closely do Mendel's insights into dominant and recessive traits match up with the ratios that Punnett calculated in his Punnett squares?

Answers

Assuming complete dominance for all the genes, a) the offspring will all be Tall and heterozygous plants. b) 3:1 ratio. c) Punnett squares are used to combinate the parental gametes and make predictions about the possible genotypes and phenotypes among the progeny. d) First generation 100% heterozygous expressing the dominant phenotype. Second generation: 25% homozygous dominant + 50% heterozygous + 25% homozgous recessive. 75% expressing the dominant phenotype + 25% expressing the recessive phenotype. e) Mendel's insight and Punnett squares match perfectly with the expected ratios.

What are complete dominance and Punnett squares?

Complete dominance is an inheritance pattern that becomes evident in heterozygous individuals. The presence of at least one dominant allele is enougth to hide the expression of the recessive allele.  In these cases, the individual expresses the dominant phenotype.

The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short plant, the offspring will all be _TALL_ plants.

All these plants will be heterozygous and express the dominant phenotype (Tall).

Tall pea plants are dominant, while short plants are recessive. In a cross between two plants heterozygous for height, the offspring will be both tall and short in a _3:1_ ratio.

1/4 = 25% of the progeny are expected to be homozygous dominant

2/4 = 50% of the progeny are expected to be heterozygous

1/4 = 25% of the progeny is expected to be homozygous recessive

25% homozygous dominant + 50% heterozygous = 75% dominant phenotype

Punnett squares discriminate parental gametes and combinates them when the columns and the rows meet. The cells where columns and rows meet (gamete combinations) gives the progeny genotypes.

describe 5 things that effect our climate as in climate change, global warming etc

Answers

Answer:

1. Greenhouse gas -  Without greenhouse gases, the Earth would be a frozen planet.

2. Increase of oxygen - The increase of oxygen caused a cooling event.

3. Asteroid impacts  - Asteroid impacts caused climate catastrophes

4. Tectonic plates - Tectonic plates can warm or cool the planet

5. Cloud covering- Cloud cover complicates global warming

Explanation:

Explanations;

1. In the greenhouse effect, gases in the Earth’s atmosphere (such as carbon dioxide, methane and nitrous oxide) trap infra-red radiation from the Earth that would otherwise be radiated to space. Thanks to this natural process, the Earth’s surface has an average temperature of 15°C w1. Without these gases, our planet would be an icy -18°C, and life as we know it would not be possible.

2. Some 2.5 billion years ago, there was no oxygen in the Earth’s atmosphere. Although the Sun was less bright back then, our planet was habitable partly because the atmospheric concentration of methane was 1000 times greater than it is now. All this changed, however, with the Great Oxygenation Event, which was triggered by the presence of blue-green algaew5. These microscopic organisms had evolved to carry out photosynthesis, and they produced oxygen as a waste product.

3. Around 66 million years ago, the 10 km diameter Chicxulub asteroid collided with the Earth, resulting in the demise of the dinosaursw7. The impact threw dust into the stratosphere, which is thought to have blocked out 50% of the sunlight reaching the Earth. This would have compromised photosynthesis and led to the collapse of food chains. It would also have resulted in a dramatic fall in global temperatures, plunging the Earth into an ‘impact winter’ that would persist for a decade.

4. The Himalayan mountain range – formed as a result of the collision between the Indian and Eurasian tectonic plates – is a prime example of how plate tectonics can have an impact on climate. Over the past 50 million years, the slow uplift of the Himalayas has exposed new rock to chemical weathering. In this process, carbon dioxide from the atmosphere binds to certain minerals in the rock, reducing the amount of atmospheric carbon dioxide and cooling the planet.

5. Clouds have important consequences for the Earth’s climate. Low, thick clouds cool the Earth’s surface, while high, thin clouds warm the climate. Key to the formation of clouds are aerosols – tiny particles that are suspended in the atmosphere. They act as tiny ‘seeds’ on which water vapour condensesw10. Aerosols are much more than simply what you find in a hairspray can. They can be natural (such as dust or sea salt) or anthropogenic (such as pollutants or smoke). An increase in anthropogenic aerosols could therefore result in more cloud formation, which (depending on the cloud height) could potentially offset the full extent of global warming.

what is the difference between a 1950 food pyramid and a 2000 food pyramid

Answers

The 1950 "Basic Four" food groups pyramid was the first food guide developed by the United States Department of Agriculture (USDA) to help Americans make healthy food choices. It consisted of four food groups: milk, meat, fruits and vegetables, and breads and cereals. It recommended eating a certain number of servings from each group every day, with an emphasis on consuming more grains and dairy products than fruits and vegetables.

The 2000 food pyramid, known as the "MyPyramid" food guide, was a more complex and personalized approach to healthy eating. It was designed to reflect the latest research on nutrition and health, and included six food groups: grains, vegetables, fruits, oils, dairy, and meats and beans. The pyramid was divided into vertical sections, with each section representing a different food group and the width of the sections indicating the proportion of each food group that should be consumed daily.

In addition, the 2000 food pyramid provided guidelines for daily physical activity and emphasized the importance of balancing food intake with exercise to maintain a healthy weight. It also included advice on portion control, moderation, and making healthy food choices within each food group.

Overall, the 2000 food pyramid represented a more comprehensive and individualized approach to healthy eating than the 1950 Basic Four food groups pyramid.

Answers

Producing 100 kg of protein A requires calculating the necessary amount of soy, calculating the necessary inputs, looking for related information, and supervising the process.

To produce 100 kg of protein A with soybeans, I must look for information related to the cultivation of soybeans, what is the protein concentration in a soybean, and other aspects necessary for its maintenance and harvest.

In this search, I find that soy has a protein concentration of 50% or higher, so if I have to get 100 kg of protein, I must get at least 200 kg of soy.

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.

What is Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.

Assuming a diallelic gene,

Allelic frequencies

The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is q

Genotypic frequencies

p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example,

Alleles          Frequencies

S^A      f(S^A) = p = 0.6S^B      f(S^B) = p = 0.4

Genotypes

S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygous

We need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate  genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).

Genotypic and Phenotypic frequencies

F(S^AS^A) = p² = 0.6² = 0.36

F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48

F(S^BS^B) = q² = 0.4² = 0.16

Number of individuals expressing each phenotype

S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individuals

1. Birds have shorter lifespans, making generations shorter.

2. The bird population is likely much greater, allowing for more data.

3. Tortoises move too slowly for natural selection to influence shell phenotype.

4. Birds are easier to track and monitor.

Answer:

The correct options are : 1, 2, and 4.

Explanation:

For the accuracy and dependability of any experiment, various observations must be as extensive as possible. It decreases the impact of any observation or any event which may have occurred by some coincidence or mistake.  

Therefore, finches were smarter to record observation as they were accessible in enormous numbers when compared with the turtle.  

Likewise, the life cycle of birds is less when contrasted with the turtle which empowered the researchers to observe more generations.  

In conclusion, the birds were anything but difficult to catch and track when contrasted with the turtle. Turtle is a land and water proficient which made it hard to follow them.

Answer:

Explanation:

vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.

Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from  a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.

Navigable Waters of the United States  For the purposes of the Clean Water Act, the term "navigable waters" includes:

all waters used in commerce, including groundwater;

all interstate waters including wetlands, mudflats, and sand-flats; and

all other waters such as lakes, rivers, streams, wetlands and sloughs.

EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters."  The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect.  In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.

Additional executive orders were issued 2015 in 2019.  Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.

Could the requirement for one or more NPDES Discharge Permit apply to my campus?

If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.

Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.

Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.

What do I have to do related to NPDES Discharge Permits?

Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.

French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

The block is in a uniform magnetic field of magnitude 0.018 T. One edge length of the block is 22 cm; the block is not drawn to scale. The block is moved at 2.3 m/s parallel to each axis, in turn, and the resulting potential difference V that appears across the block is measured. With the motion parallel to the y axis, V =17 mV; with the motion parallel to the z axis,V = 12 mV; with the motion parallel to the x axis, V = 0. What are the block lengths (a) dx, (b) dy, and (c) dz?
