Answer:
Behavioral Perspective
Explanation:
The fact that "small changes are introduced in the child's environment" can be taken as a good example of behavioral perspective since the ones that work with this idea consider that evironment has an important influence in behavior. They have the conception that when interacting with a given environment an individual can develop certain attitudes and responses.
Answer:
Two 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.
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. Two different ways by which antiretroviral drugs can prevent the formation of virus are:
- <em><u>Inhibition of reverse transcriptase enzyme</u></em><em>: 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.</em>
- <em><u>Enzymatic Inhibition of Integrase enzymes</u></em><em>: 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.</em>
The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.
Answer:
Chromosomal inversion
Explanation:
Inversion is a type of mutation which occurs in the chromosome structure in which the chromosome region breaks at two points and the region between the break and rotates to 180°. The rotated region after rotation rejoins with the end of the chromosomes.
Sometimes these break occurs in the region of the gene and the inversion of the sequence of the gene proves a lethal mutation like in the case of haemophilia in humans.
Thus, Chromosomal inversion is the correct answer.
Answer:Of the more than 7,000 chemicals in tobacco smoke, at least 250 are known to be harmful, including hydrogen cyanide, carbon monoxide, and ammonia (1, 2, 5). Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer. Explanation:
The liquid part of the blood which carries red blood cells, white blood cells,and platelets is called plasma
