It destroys harmful substances or worn-out cell parts is a cell organelle lysosome. it is present in the eukaryotic cell and helps the cell protect itself from the virus or other harmful molecules.

The lysosome that is present in the cell has maintained an acidic environment because of the active transport of hydrogen from the cytoplasm to the lysosome. Due to its acidic nature, it can degrade the harmful pathogens in the cells and also degrade worn out cells, such as old mitochondria, and in this way, the lysosome protects the cell.

Hence, lysosomes destroy harmful substances or worn-out cell parts.

Answer:

It is a test to check the protein's solubility.

Explanation:

Proteins have varying levels of solubility and it is necessary to carry out tests that prove in which aqueous media the proteins are more likely to have high levels of solubility. This facilitates the execution of scientific works that develop products that work with proteins.

The level of solubility of proteins depends on the distribution of the polar and nonpolar groups of this molecule.

The most common test is done by adding water and protein to a beaker. An example of this is done by adding part of egg albumin mixed with two parts of water.

Answer:

D. that has a definite volume, but no definite shape

Explanation:

There are mainly three states of matter and these are: solid, liquid and gas.

Liquid has a definite volume because its particles still remain in contact although they're moving freely. On the other hand, such free movement of the particles render it to have "no definite shape." This is the reason why liquid takes the shape of the container it is poured into.

If you pour a 500-ml liquid into a rectangular-shaped container, it will look rectangular. However, its volume of 500-ml will remain the same.

Answer:

It is important that cell membranes are semipermeable because it allows the cell to regulate the substances that enter and exit the cell. Semipermeable membranes allow certain molecules to pass through while blocking others, allowing the cell to selectively choose which substances and molecules to allow in. This helps the cell to maintain balance and control the environment inside the cell. Additionally, semipermeable membranes allow the cell to absorb nutrients and expel waste, which is essential for the cell's health and survival.

Explanation:

Plants employ the process of photosynthesis to transform water and carbon dioxide into carbohydrates and oxygen.

Light energy is absorbed by the plant during photosynthesis and transformed into chemical energy. The oxygen is released into the environment, while the water and carbon dioxide are disintegrated into their component elements.

In the plant, the sugars are kept for future use. It is possible to write the photosynthesis equation as follows:

Light energy + water + carbon dioxide →  sugars + oxygen.

Light energy → chemical energy can be used to describe the energy transformation equation.

You are on the right track, but there are some errors in your calculations and some steps missing. I will guide you through the correct calculations step by step.

First, we need to calculate the allele frequencies in the population. Let p be the frequency of the dominant allele (A1), and q be the frequency of the recessive allele (A2). We can calculate these frequencies using the formula:

p^2 + 2pq + q^2 = 1

where p^2 is the frequency of homozygous dominant individuals (RR), 2pq is the frequency of heterozygous individuals (Rr), and q^2 is the frequency of homozygous recessive individuals (rr).

Substituting the given values, we get:

0.3 + 0.4 + 0.3 = 1

So, p^2 = 0.3, 2pq = 0.4, and q^2 = 0.3.

From these values, we can calculate the allele frequencies as:

p = sqrt(p^2) = sqrt(0.3) = 0.55

q = sqrt(q^2) = sqrt(0.3) = 0.55

Next, we need to calculate the selection coefficients (s) for each genotype. The selection coefficient (s) represents the reduction in relative fitness compared to the most fit genotype. We can calculate the selection coefficients as:

s11 = 1 - w11 = 1 - 0.7/0.8 = 0.125

s12 = 1 - w12 = 1 - 1 = 0

s22 = 1 - w22 = 1 - 0.5/0.8 = 0.375

where w11, w12, and w22 are the relative fitness values for the RR, Rr, and rr genotypes, respectively.

We can then calculate the average relative fitness (w-bar) of the population as:

w-bar = p^2(1 - s11) + 2pq(1 - s12) + q^2(1 - s22)

Substituting the values, we get:

w-bar = 0.55^2(1 - 0.125) + 2(0.55)(0.45)(1 - 0) + 0.45^2(1 - 0.375) = 0.862

Next, we can calculate the expected genotype frequencies in the next generation using the formula:

p^2 = expected frequency of RR genotype

2pq = expected frequency of Rr genotype

q^2 = expected frequency of rr genotype

We can calculate these values using the following equations:

expected frequency of RR genotype = p^2(1 - s11)/w-bar

expected frequency of Rr genotype = 2pq(1 - s12)/w-bar

expected frequency of rr genotype = q^2(1 - s22)/w-bar

Substituting the values, we get:

expected frequency of RR genotype = (0.55^2)(1 - 0.125)/0.862 = 0.232

expected frequency of Rr genotype = 2(0.55)(0.45)(1 - 0)/0.862 = 0.508

expected frequency of rr genotype = (0.45^2)(1 - 0.375)/0.862 = 0.26

Finally, we can calculate the expected number of individuals of each genotype in the next generation by multiplying the expected genotype frequencies by the total population size of 100. So, the expected number of individuals of each genotype in the next

Answer:

Soil nutrient loss

Algae blooms

Pollution of water ways

Explanation:

Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.

Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.

Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.

Limited inherited behaviors exist. The parent or group can effectively educate the young how to hunt, migrate, etc. by using learnt behaviors. They therefore remain alive, procreate, and the cycle is maintained. People who have learned behaviors are therefore "selected for."

Because learned behaviors do not increase the likelihood that an individual will live and reproduce, they do not directly influence natural selection. Organisms pass on their survival strategies to their progeny as they learn to adapt to their surroundings.

Natural selection is another process that can mold behavior. The ability to learn language in humans, the wiggle dance of bees, and avian mating rituals are just a few examples of behaviors that are subject to natural selection and have genetic roots.

The sensory receptors in the vestibular sacs enable us to maintain our sense of equilibrium by detecting the movement of fluid within them and transmitting this information to the brain. This helps us to stay upright, maintain balance, and navigate through our environment.

Sensory receptors in your vestibular sacs enable you to maintain your sense of equilibrium. The vestibular sacs are situated in the inner ear and are a vital component of the vestibular system that is responsible for maintaining balance and spatial orientation. These small, fluid-filled sacs contain tiny hair cells that are sensitive to the movement of the fluid as we move around.

The vestibular sacs consist of two small pouches, the utricle and saccule. The utricle is located horizontally, and the saccule is oriented vertically. They work together with the semicircular canals to provide sensory information to the brain that is necessary to maintain our balance and spatial orientation.

When we move our head, the fluid inside the vestibular sacs moves in response to the movement, causing the tiny hair cells to bend. This bending of hair cells generates electrical impulses that are transmitted to the brain via the vestibular nerve. The brain uses this information to determine the orientation of the body and the direction of movement.

The alternate hypothesis suggests that invasive Burmese pythons are responsible for recent increases in human Everglades virus infections.

The hypothesis that invasive Burmese pythons are responsible for recent increases in human Everglades virus infections is an alternate hypothesis to the commonly accepted idea that the virus is transmitted through mosquitoes. While it is true that Burmese pythons have been introduced to the Everglades and are known carriers of certain viruses, there is currently no direct evidence linking them to human infections of Everglades virus.

In fact, studies have shown that the majority of human cases of Everglades virus occur during the rainy season when mosquito populations are at their highest. Additionally, genetic analyses of the virus have identified specific mosquito species as the primary vectors of transmission.

While it is possible that Burmese pythons could indirectly contribute to the spread of Everglades virus by altering the ecosystem and increasing the abundance of mosquito breeding sites, there is not yet enough evidence to support this hypothesis.

In conclusion, while scientists may hypothesize that invasive Burmese pythons are responsible for recent increases in human Everglades virus infections, the current data does not provide sufficient support for this alternate hypothesis.

The mechanistic organization emphasizes flexibility and is less rigid than the organic structure. This statement is false. The statement "The mechanistic organization emphasizes flexibility and is less rigid than the organic structure" is false.

Mechanistic organizations are known for their formalized and rigid structure, where communication flows in a top-down direction. They are better suited to larger companies with a more complex internal structure and greater job specialization. In contrast, organic organizations are more adaptable and flexible, which is advantageous in rapidly changing environments and dynamic situations.

The two types of organizational structures can be defined as follows: Mechanistic structure: A mechanistic organization is characterized by highly formalized and centralized structures. There is a rigid division of labor, strict hierarchical control, and formal communication channels, with an emphasis on consistency, efficiency, and stability. Mechanistic organizations are more suited for large, bureaucratic firms that have a complex internal structure and greater job specialization. Organic structure: An organic organization, on the other hand, is less formalized and hierarchical than a mechanistic organization.

It is characterized by loose or informal structures, which enable rapid and flexible communication. In an organic organization, employees have greater autonomy and are expected to be more entrepreneurial, with less reliance on formalized procedures and protocols. Organic organizations are better suited for smaller and more dynamic firms, as well as firms that are rapidly changing.
