Answer: C. The land is in all probability changing because of the course of shedding, a sort of disintegration that makes chunks of stone split away.

Rocks can expand or crack as a result of rapid temperature changes. This particularly occurs with granitic rocks as they were cooling, as at Yosemite Public Park. Freeze-thaw: Water expands when it freezes. Before winter, moisture that seeps into cracks may freeze, breaking the rocks apart.

The process of large, flat or curved sheets of rock breaking away from the outcrop as a result of pressure release is known as exfoliation. Cracks and fractures along the sheet are the result of erosion removing the overburden from a rock that was formed at high pressure deep in the Earth's crust.

Recombination is possible and can generate a wild-type allele and a double mutant allele ( D )

Explanation:

The true statement regarding the recombination between the alleles is : Recombination is possible and can generate a wild-type allele and a double mutant allele.

The recombination process involves the breaking and recombination of pieces of DNA in order to produce new alleles. this recombination ( crossover ) results to the offspring possessing different combination of genes ( wild -type allele and double mutant allele ).  hence option D is the correct answer.

Answer: D. a bat

Explanation:

A bat just picks up on the sound waves but does actualy hear stuff

D. A bat would be least affected by sound frequencies of 25,000 to 100,000 cycles per second. Bats use ultrasonic frequencies in their echolocation calls to navigate and locate prey, they have specialized ears and auditory systems that allow them to hear and process these high frequency sounds. While other animals like human, cheetah, porpoise and house cat would not be able to hear these ultrasonic frequencies and would not be affected by them.

Evolution- The process of evolution in populations over time that makes descendants different from their ancestors. Two types- Microevolution- Evolution can occur on a genetic level, affecting a species population. Macroevolution- Evolution on a genetic level affecting changes in traits across population.

Species is a classification of biological organisms, usually based on common characteristics. Traits, on the other hand, are individual characteristics of an organism. A species can have many different traits, but all individuals belonging to that species will share certain common characteristics that differentiate them from other species.

Charles Darwin

- English Naturalist

- Went on a voyage to the Galapagos Islands.

- Saw that varieties of finches, tortoises, and other animals lived on different islands and had specific adaptations for that island

- Developed his theory of Natural Selection to serve as the mechanism for how Evolution occurs.

Natural selection- Organisms with a "heritable" traits (adaptations) will live longer and reproduce more than others, causing changes in the population over time by acting on the traits that are beneficial.

- Survival of the Fittest.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

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.

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

Genotypic frequencies

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

Genotypes

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

Carbon sources are any natural or artificial production site of carbon and/or any chemical compounds composed of carbon, such as carbon dioxide and methane.

Carbon source: Combustion,Respiration.

A carbon sink absorbs carbon dioxide from the atmosphere.

Carbon sink: Photosyntheis,Ocean absorption,Fossilization.

1. Photosyntheis: Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis.

2. Ocean absorption: Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a impotant role in carbon cycle - absorbing carbon.

3. Fossilization: Absorb CO2.

4. Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat and CO2 in environment.

5. Respiration:  The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells and gives out CO2 in atmosphere.

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

Adaptation is an evolutionary process. Under this process an animal or plant evolves to become suitable to  live in a particular habitat. The organism undergoes many changes through natural selection, such changes takes place over generations. Although scientists were discussing adaptation before 1800s, it came to limelight only after the development of theory of natural selection by Alfred Russel and Charles Darwin.

Adaption can be of three types: Behavioral, Physiological and Structural

3. All organisms need _____ and ______ to survive, grow, and reproduce.

B. oxygen, sunlight.

4. A consumer is an organism that gets D: Matter and energy by eating other organisms as food.

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, while releasing oxygen as a byproduct. In this process, carbon dioxide and water are converted into glucose (a type of sugar) and oxygen.

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose and oxygen gas. Its equation is:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Respiration, on the other hand, is the process by which organisms convert glucose and oxygen into usable energy, releasing carbon dioxide and water as byproducts. Its equation is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
