When the feather is covered with oil, it causes an increase in the mass and makes them unable to fly. Yes, Natalia can clean off the feather using water. As she will dip the feather in water it can clean the feather but also remove the natural waterproofing.

What is an oil spill?

Accidentally pouring a large amount of oil onto the large water body surface is referred to as an oil spill.

As due to this, the bird feather will get into the oil and increases its mass and the appearance as it cause them to become mat and separate.

Natalia can clean the feather using water.

When she will put the feathers covered with oil in either cold or hot water will cause the removal of natural waterproofing of the feather.

Thus, these were the consequences according to the given scenario.

Explanation:

There are different types of natural selection. When one of the extremes phenotypes is being favored, directional selection is going on. Meanwhile, balancing selection increases the proportion of intermediate phenotype.

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

Since I do not have the graphs, I will set different potential scenarios

Scenario 1: More light brown individuals than brown and dark brown

Probably after the dark-colored seaweed covered the rocks, snails needed to camouflage to avoid predation. So they must have suffered a change in color from light brown to dark brown.

Since this new trait is beneficial, natural selection favored it.

So animals change from being light brown to dark brown.

The type of natural selection acting here is directional selection.

A population that is under the effects of directional selection, experiences an increase in the proportion of individuals expressing an extreme phenotype, different from the original one.

In these cases, interactions between living organisms and the environment modify in the same direction.

So, the most abundant individuals turned from being light brown to being dark brown.

After dark-colored seaweed covered the rocks, the number of dark brown individuals increased, and the light brown individuals decreased.

                                            **********************

Scenario 2: More brown individuals than light brown and dark brown

This is the same situation as before. In this case, there were more brown individuals than snails expressing extreme phenotypes.

                                            **********************

Scenario 3:

Let us suppose that the original number of individuals was higher for one of the extreme traits, either yellow or grey.

After the seaweed-covered rocks, snails needed to camouflage to avoid predation, so they changed their color from yellow or grey to brown.

In this scenario, the intermediate phenotype is being favored by natural selection over the extreme phenotypes.

Balancing selection -or Stabilizing selection-, decreases the number of individuals expressing the extreme phenotype and favors individuals that exhibit medium-range characteristics. These are the ones that get to survive. Selective pressure is against h0m0zyg0tes.

In this case, the number of individuals expressing yellow or grey shells decreases, while individuals with brown color increase.

In the attached files you will find graphs for the three scenarios.

TP53 is tumor suppressor gene that experiences the most mutation in cases of human cancer. Missense mutations, which produce completely modified p53 proteins, account for the majority of p53 mutations.

Instructions for producing the tumor protein p53 are found in the TP53 gene (or p53). This protein controls cell division by acting as a tumor suppressor, which stops cells from proliferating (growing and dividing) too quickly or uncontrolled. Every cell in the body contains the p53 protein, which binds (attaches) to DNA there. This protein is crucial in determining whether DNA damage caused by radiation, harmful compounds, or ultraviolet (UV) rays from sunlight will be repaired or the wounded cell will self-destruct (undergo apoptosis). P53 activates additional genes to repair DNA damage if it is possible to do so. This protein prevents the cell from dividing and signals apoptosis, or cell death, if the DNA cannot be repaired. P53 aids in the prevention of tumor growth by preventing the division of cells with damaged or altered DNA. The protein p53 is referred to as the "guardian of the genome" and is crucial for controlling DNA repair and cell division. According to reports, somatic TP53 gene mutation have been discovered in certain bladder cancer cases.

When a compound changes the shape of an enzyme by binding to it, and consequently the substrate cannot enter the active site, the compound is called a noncompetitive inhibitor.

Biological polymers that catalyse biochemical reactions are what are known as enzymes.

Most enzymes are proteins having catalytic properties that are essential to carry out various operations. A group of enzymes that are essential for maintaining life carry out metabolic processes and other chemical reactions within the cell.

The pancreas, small intestine, and stomach all produce digestive enzymes. The "powerhouse" of enzymes for digestion is actually the pancreas. The most vital digestive enzymes—those that liquefy fats, proteins, and carbohydrates—are produced by it.

Nitrogen is present in all of the options listed except for monosaccharides. Thus, correct option is (E).

A crucial component of biological compounds is nitrogen. Nitrogen is a component of proteins, nucleic acids (DNA and RNA), amino acids (which serve as the building blocks for proteins), and DNA. Amino acids, which make up proteins, contain nitrogen as a necessary part of their structure.

Adenine, cytosine, guanine, and thymine/uracil are nitrogenous bases that are essential for the operation of nucleic acids, including DNA. Monosaccharides, simple sugars and the fundamental unit of carbohydrates, do not, however, include nitrogen. Instead, the majority of their atoms are made up of carbon, hydrogen, and oxygen.

Scientists use historical major geological and biological events to characterise the geological time scale.

Paleontologists, archaeologists, and geologists use the fossil record to put significant occurrences and species in the right geological epoch. The geologic time scale is fundamentally based on fossils. Because these time periods are frequently identified based on the presence of animal life, the names of the majority of the aeons and eras end in zoic. Fossil remains of relatively simple organisms, like bacteria, algae, and worm-like animals, have been found in rocks formed during the Proterozoic Eon.

There are seven different types of criteria for naming skeletal muscles:

Location: Some muscles are named based on their location in the body, such as the pectoralis major (located in the chest) or the quadriceps femoris (located in the thigh).

Shape: Some muscles are named based on their shape, such as the deltoid (triangular), trapezius (trapezoidal), or orbicularis (circular).

Size: Some muscles are named based on their size, such as the gluteus maximus (largest muscle in the buttocks) or the adductor magnus (largest muscle in the inner thigh).

Direction of fibers: Some muscles are named based on the direction of their fibers, such as the rectus abdominis (fibers running vertically) or the transverse abdominis (fibers running horizontally).

Number of heads: Some muscles are named based on the number of heads or points of origin, such as the biceps brachii (two heads) or the quadriceps femoris (four heads).

Action: Some muscles are named based on their action or function, such as the flexor carpi radialis (flexes the wrist and abducts the hand) or the extensor digitorum (extends the fingers).

Origin and insertion: Some muscles are named based on their points of origin and insertion, such as the sternocleidomastoid (originating from the sternum and clavicle and inserting on the mastoid process of the skull).

The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.

The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.

Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.

Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

Recombination and independent assortment are the two events that increase genetic variation.

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

This variety of potential gametes is the result of homologous pair orientation during metaphase of meiosis I and crossing over.

CROSSING OVER: Every cell that undergoes meiosis has a unique set of places where homologues cross across and exchange genetic material. These locations are mostly picked at random. Crossovers will take place at numerous distinct places if meiosis occurs often, as it does in the ovaries and testes of humans. Recombinant chromosomes, or chromosomes where DNA fragments have been exchanged between homologues, are produced in a vast diversity as a result of this repetition.

INDEPENDENT ASSORTMENT: Another significant source of gamete variation is the random orientation of homologous pairs during metaphase of meiosis I.

Thus, by these two processes the genetic variation is maintained and thus each gamete is different from other.

David is swimming in a cold swimming pool. His scrotum is likely to be contracted or tightened.

The scrotum is the loose pouch of skin that holds the testicles. When exposed to cold temperatures, the scrotum undergoes a reflex called the cremasteric reflex, causing the scrotum to contract or tighten. This physiological response helps to bring the testicles closer to the body, reducing their exposure to the cold environment and helping to maintain optimal temperature for sperm production.

The contraction of the scrotum helps to protect the testicles and maintain their functionality by minimizing heat loss and ensuring a suitable environment for sperm development.
