Answer:
a. True
Explanation:
AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).
AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.
Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.
Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
<em>Hence, the human immunodeficiency virus (HIV) possesses a high error rate. </em>
PVC (Polyvinyl Chloride) is one of the most widely produced synthetic plastic polymer. <span>PVC produces a great deal of vapor which can cause eye irritation, headaches, dizziness and respiratory problems. When heated, PVC products can produce HCL fumes, which are toxic to humans.
</span><span>Skin contact with PVC may lead to a painful, itchy red rash. Prolonged, repeated exposure can lead to dermatosis (a skin condition affecting the face and neck). Therefore gloves must be used. If contact occurs, the affected area should be immediately washed with water.</span>
Training would usually have consent of the trainee in the situation, to bring new ideas, knowledge or practice of a skill or trade. Indoctrination is forcibly bringing ideas, practices, or concepts into an environment.
Answer:
Yes. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. ... Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent
