accurately 3 different ways that antiretroviral drugs can prevent virus formation.
Answer:
Three different ways in which antiretroviral drugs can prevent the formation of new viruses are:
Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.Enzymatic inhibition of integrase enzymes.Inhibiting entry by antagonizing CCR5 co-receptors.Explanation:
Antiretroviral drugs are those used for the treatment of human immunodeficiency virus (HIV) infection, making the effect of the virus on the host cell is less and preventing the development of AIDS.
This type of drug has been classified, according to their mechanism of action, being grouped into several families of drugs. Three different ways by which antiretroviral drugs can prevent the formation of virus are:
Inhibition of reverse transcriptase enzyme: this enzyme is a DNA polymerase capable of forming single strand viral RNA by a process that is reverse to normal DNA to RNA transcription. Its inhibition prevents the formation of viral particles in the host cell. They are divided into nucleoside analogs and non-nucleoside analogs.Enzymatic Inhibition of Integrase enzymes: this type of enzyme is contained in the virus, and is capable of causing a retrotranscribed DNA to integrate into the host cell's DNA so that viral replication occurs. Its inhibition prevents the replication process.Entry inhibitors or antagonists CCR5 co-receptors: CCr5 is a membrane protein, found on the surface of CD4 T lymphocytes, which facilitates the entry of the virus into the cell. The drug acts as a competitive inhibitor of the viral particle, preventing the entry and infection of the host cell.The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.

Illiteracy is the main cause of low quality of life
Question: Illiteracy is the main cause of low quality of life. Justify.
Answer/Explanation:
Illiteracy is the lack of knowledge, or the inability of someone to read and write. Those who do not have formal education oland are without education certificates can be considered illiterates.
Low quality of life can be said to be characterized by poor health, low standard of living, lack of comfort, inability to afford basic needs, etc.
Thus, to have high quality of life, one needs to have the financial capacity and knowledge to afford a high standard of life.
Therefore, someone who is an illiterate would either not have the right knowledge to have a high quality life nor have the financial capacity to afford one.
Therefore, illiteracy is the main cause of low quality of life.

All cells share the following common components except
Answer:
All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.

Figure 1. This figure shows the generalized structure of a prokaryotic cell.
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).
Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
Eukaryotic Cells
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.
A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions.
Cell Size
At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 2). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. Similarly, any wastes produced within a prokaryotic cell can quickly move out. However, larger eukaryotic cells have evolved different structural adaptations to enhance cellular transport. Indeed, the large size of these cells would not be possible without these adaptations. In general, cell size is limited because volume increases much more quickly than does cell surface area. As a cell becomes larger, it becomes more and more difficult for the cell to acquire sufficient materials to support the processes inside the cell, because the relative size of the surface area across which materials must be transported declines.

Figure 2. This figure shows the relative sizes of different kinds of cells and cellular components. An adult human is shown for comparison.
IN SUMMARY: COMPARING PROKARYOTIC AND EUKARYOTIC CELLS
Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. Eukaryotic cells tend to be 10 to 100 times the size of prokaryotic cells.

Describe the four primary factors in attraction and why each is important to relationship formation.
Answer:
The four primary factors in attraction are proximity, physical attractiveness, similarity, and reciprocal liking. ... The nearer two people are to one another, the more likely they are to develop a relationship.
Explanation:
The four factors in attraction are physical attractiveness, proximity, similarity, and responsiveness. Each factor governs the significant control over the relationship development.
What do you mean by Attraction?An attraction may be defined as a quality that supervises to pull others in or concoct interest in the person or thing.
Physical attractiveness is the primary factor that plays a significant role in relationship formation. Physical attractiveness leads to proximity or stabilizing closeness between one another.
Similarity overall reveals the common behavior, thoughts, and feelings of both individuals. Responsiveness determined the stability of any relationship.

Answer:
source wiki
Explanation:
Stress, either physiological or biological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. Stimuli that alter an organism's environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal axis are the two major systems that respond to stress.

Answer:
First line of defense ⇒ Includes mechanical barriers that prevent microorganisms from entering the body.
The presence of mechanical barriers such as the skin cover up the body and massively reduce the amount of microorganisms coming into the body.
Second line of defense ⇒ A complex defense that recognizes and reacts to specific organisms.
The body uses the protein presence on the organism to recognize that it is foreign as foreign cells have a different protein synthesis process than your own.
Third line of defense ⇒ Includes cells and process that help remove or neutralize organisms that have penetrated mechanical barriers.
Cells such as the Lymphocytes and Phagocytes work to neutralize the foreign organisms. Lymphocytes produce antibodies and Phagocytes ingest and neutralize them.
