After the drug has been in use, patients and doctors report that the drug is not as effective as it once was, the most likely explanation for this result is (D) Some HIV viruses have genetic variations in the RNA genome that provide resistance to the actions of the drug.

It is not always the case that a person who has been exposed to the HIV virus will eventually get AIDS. Some individuals have a natural defense against HIV infection due to their genetic makeup. Dr. Stephen O'Brien, a researcher at the National Cancer Institute in the United States, has just discovered a variant of the gene known as CCR5 gene known as a mutant that can defend against HIV infection. It's likely that the mutation first appeared in Europe, where it then spread via populations of people who had survived the bubonic plague. Plague germs are unable to enter and infect body cells because a defective gene stops them from connecting to the cellular membranes and, as a result, from entering the body. So the correct option is (D).

The correct answer is D. Igneous rock.

Igneous rocks are the most common type of rock by volume in Earth's crust. They are formed through the solidification and crystallization of molten magma or lava. Igneous rocks can be classified into two main categories: intrusive igneous rocks and extrusive igneous rocks.

Intrusive igneous rocks form beneath the Earth's surface when molten magma cools and solidifies slowly. Examples of intrusive igneous rocks include granite and diorite. These rocks make up a significant portion of the Earth's crust.

Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava erupts from volcanoes and rapidly cools and solidifies. Examples of extrusive igneous rocks include basalt and rhyolite. While these rocks may cover extensive areas on the Earth's surface, they are less voluminous compared to the intrusive igneous rocks that form beneath the surface.

Metamorphic rocks (A) are formed when existing rocks undergo changes due to high heat, pressure, or chemical processes. Sedimentary rocks (B) are formed from the accumulation and compaction of sediments over time. Divergent rock (C) and convergent rock (E) are not recognized geological terms.

Therefore, the most common type of rock by volume in Earth's crust is igneous rock (D).

Explanation:

It houses glucose, which plants use for food. The presence of starch in a leaf is reliable evidence of photosynthesis. That's because starch formation requires photosynthesis.

The phenotype is affected by mutations 1 and 2 because in the first, the complete protein is altered, and in the second, the new amino acid may cause the protein to have altered or no function.

Mutations can happen naturally or as a result of UV rays, congenital conditions, ionic radiations, or specific free radicals.

Even with the point mutation, there is no alteration to the amino acid sequence, hence the protein will not be affected.

In mutation 1, a new nucleotide is added at codon 9, changing the whole sequence of amino acids and codons in the process,  mutation frameshift.

Because a new codon was created as a result of the substitution of one nucleotide by another in mutation 2, produced a new amino acid, so Point mutation.

Therefore, in mutation 3, one nucleotide is swapped out for another, and the resulting codon codes the same amino acid as the one before it, so point mutation.

Langerhans cells are the cells of the epidermis that function as phagocytes of the immune system. They play a crucial role in the immune response by detecting and capturing foreign particles that penetrate the skin and presenting them to T cells to initiate an adaptive immune response.

The cells of the epidermis that function as phagocytes of the immune system are Langerhans cells.

The epidermis is the outermost layer of skin that serves as a barrier to protect the body from environmental threats like pathogens, UV radiation, and chemicals.

This layer is responsible for keeping the body hydrated and regulating body temperature, among other functions.The cells of the epidermis

There are four primary types of cells in the epidermis: keratinocytes, melanocytes, Merkel cells, and Langerhans cells.

Keratinocytes are the most numerous cells in the epidermis and produce the protein keratin, which gives the skin its strength and waterproofing properties.

Melanocytes produce the pigment melanin, which gives the skin its color and helps protect against UV radiation.

Merkel cells are specialized touch receptors that are involved in sensory perception.

Langerhans cells, on the other hand, are involved in the immune response.Langerhans cells

Langerhans cells are dendritic cells that are present in the epidermis and other stratified squamous epithelia of the body.

They play a crucial role in the immune response by capturing antigens and presenting them to T cells in the lymph nodes to trigger an adaptive immune response.

They act as sentinels to detect and capture antigens that penetrate the skin, including bacteria, viruses, and other pathogens. Once they capture these foreign particles, they travel to the lymph nodes to present the antigens to T cells.Langerhans cells express a variety of pattern recognition receptors that allow them to detect different types of antigens, including toll-like receptors, scavenger receptors, and lectins. These receptors enable them to recognize and capture a wide range of pathogens and other foreign particles.

Phagocytes Phagocytes are cells that can engulf and destroy foreign particles, including pathogens and dead or damaged cells. Langerhans cells are phagocytes, as they are capable of ingesting and digesting antigens that they encounter.

Once they ingest these particles, they break them down into smaller fragments and present them to T cells to initiate an immune response.

Triglycerides are used as the primary energy source by muscles during low-intensity physical activity and when the body is at rest.

The human body has three primary macronutrients, carbohydrates, proteins, and fats, that provide the necessary energy for various physical activities. Fats are stored in the body as triglycerides. They provide the most abundant energy source, primarily for low-intensity physical activities.

When the body is at rest, there is a slow but continuous rate of energy expenditure to carry out the body’s functions like breathing, heart beating, digestion, and other biological activities. During these resting periods, the triglycerides provide the majority of the energy required by the body. The consumption of triglycerides for energy production during rest can be explained by the fact that the body requires a low energy output for the maintenance of metabolic processes.

On the other hand, during high-intensity physical activity, the body requires more energy output to support the muscles' increased power. Triglycerides cannot meet this requirement, and the body switches to glucose as its primary energy source. During high-intensity physical activities, the demand for energy is high, and the triglycerides breakdown slowly; thus, glucose provides the necessary energy more efficiently.
