It will take 15 years for Della to be in the same risk of non-smoking persons in risk of cardiovascular disease. As you quit smoking, the lungs will start to purify itself, but it will take some time. On the other hand, it cannot be assured that the lungs may be totally restored, more or less it would just be clean over a period of time.

HIV can remain latent for several years and not cause any symptoms in its host. What viral reproduction cycle is occurring durin
lakkis [162]

Answer:

The lytic cycle.

Explanation:

<u>HIV is a retrovirus</u> that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.

When there is a triggering event, <u>this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery.</u> <u>Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. </u>This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.

All of the following are examples of informational social influence except:
Cerrena [4.2K]

Answer:

c. when you get to college you change the way you dress so that you "fit in" better--that is, so that people will like you more.

Explanation:

Informational social influence leads to internalization (private acceptance) of the majority opinion/behaviour i-e you actually change your attitude / belief. It is basically a difficult task , unsure of the answer, usually ambiguous , actually use others's response to form an opinion and actually believe what others say and internalize in. It is usually found in the crisis situation, when you don't know what to do and following th advice of expert. Examples include listening to fireman.

Hence in the given options, only c. when you get to college you change the way you dress so that you "fit in" better--that is, so that people will like you more. seems not to be example of Informaltiona social influence.

How would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would increase cAMP levels, which wou
dedylja [7]

Answer:It would maintain high cAMP levels and elevate glucose mobilization.

Explanation:

Gas stimulates adenylate cyclase, leading to the generation

of cAMP. This signal then leads to glucose mobilization. If cAMP phosphodiesterase were inhibited, then

cAMP levels would remain high even after the termination of the

epinephrine signal, and glucose mobilization would continue

Which of the following best describes the function of fruits? Group of answer choices
ratelena [41]

The correct answer is B. Protection and dispersal of seeds

Explanation:

In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.
