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

Over time, California wildfires have become more frequent, intense, and destructive due to a combination of factors such as climate change, drought, and increased human activity in fire-prone areas.

The state has experienced some of its largest and deadliest wildfires in recent years, including the 2017 Wine Country fires, the 2018 Camp Fire, and the 2020 August Complex Fire. These fires have not only caused significant property damage and economic losses but also resulted in loss of life and long-term health effects for residents.

The trend of more frequent and intense wildfires is likely to continue unless effective measures are taken to address the underlying causes and prevent their occurrence.

Explanation:

The majority of organelles are found in both plant and animal cells. Cells do not have a cell wall, a big central vacuole, or plastids like chloroplasts. Plant cells, on the other hand, do.

A photosynthetic unit is a leaf. They are the plants' organs best suited and most adapted to photosynthesis for the following reasons: Chloroplasts, or cells containing chlorophyll, are found in leaves. Stomata found there aid in the gas exchange.

First, in a process known as light-dependent processes, autotrophs absorb energy from the sun. The acquired solar energy is then transformed into potential energy in the second stage, known as light-independent and dark reactions, which is present in autotrophs in chemical bonds within macromolecules.

Answer:

water molecules move according to the energy from where they are to where they're going.

Explanation:

The external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.

A cell membrane may be defined as a type of biological membrane that significantly separates and protects the interior environment of all cells with respect to the outside environment. It is semi-permeable in nature which regulates the transport of materials entering and exiting the cell.

If a cell is placed in a hypertonic solution, water will migrate out of the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Therefore, the external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.

A steroid hormone approaches its target cell, therefore the hormone will enter the nucleus and is what will happen first which is therefore denoted as option A.

This is referred to as a chemical messenger which is released directly into the bloodstream and is responsible for the control of certain metabolic reactions occurring in the cell and  an example is steroid hormone such as androgens.

In a situation whereby a steroid hormone approaches its target cell, it first passes through the plasma membrane before it then becomes adhered to the receptors which are present in the nucleus or cytoplasm.

He discovered that birds were twice as likely to eat a bright moth as a dark insect on dark tree trunks.

If the tree's bark was light, the same birds would notice the dark moth twice as frequently. This provided evidence in favor of the hypothesis that dark moths would fare better in a dark forest.

In the middle of the 1950s, Kettlewell conducted a biological experiment to investigate the peppered moth's industrial melanism's evolutionary mechanism.

The investigation revealed that birds hunt on peppered moths selectively depending on their body color in relation to their background surroundings.

Therefore, He discovered that birds were twice as likely to eat a bright moth as a dark insect on dark tree trunks.

The question is unclear, is there more to it?

I cannot answer this question without knowing the circumstances, but it is good to remember that mutualism is where both species and/or participants benefit, and parasitism is where one species benefits and the other one is harmed.

Think of mutualism like the word mutual, so when people say " the feeling is mutual" it means that both parties feel and/or express the same feelings. Parasitism should be thought of like a parasite. When one is infected or has contracted a parasite, the parasite will live off of its host body making it ill or even causing death as it drains resources from its host to benefit itself.

Anaerobic respiration is the short and quick way of producing energy, however, it produces less amount of energy than aerobic respiration and produces lactic acid as a byproduct. It takes place in the cytoplasm of the cell and working or acting muscles depend on such respiration.

Aerobic respiration is the main and important respiration process that takes place in mitochondria and it takes time to produce ATPs that are much more than anaerobic respiration. Resting muscles get energy by this type of respiration.

Proteins there are complex macromolecules that perform a great number of functions in the body, some are even part of structures in the body, one example is hair or nails. Thus they are necessary for the structure, function, and regulation of tissues and organs in the body. W

The process of protein synthesis is important because our bodies need to be able to produce proteins that are essential to our health and well-being. Hormones, enzymes, and the growth of muscles cannot be made in our bodies without protein synthesis.

Protein synthesis accounts for the majority of amino acid disposal. A specific sequence of amino acids is defined by messenger RNA, which has been transcribed from a DNA template and binds to specific molecules of transfer RNA.

The adjacent amino acids form peptide bonds. As soon as the polypeptide chain is completed, the sequence of amino acids determines the subsequent folding, post-translational amino acid modifications, and protein packaging.

Transcription rate, ribosome aggregation, and modulation of peptide synthesis rate determine the rate of protein synthesis.

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.
