Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.

harkovskaia [24]

If given a chance to advice Mr. Smith, I would recommend him to minimize going out in the sun when it is at the peak of the morning but if not possible since he works under the sun, it would be good to put on sunblock with a highest SPF and use precautionary measures like using hats and wearing long sleeve to protect also the skin.  More water to hydrate, and vitamins for skin protection.

The pathway between the ventral tegmental area (VTA) and the _____ is critical for the addiction process because lesions to this
Airida [17]

The pathway between the ventral tegmental area (VTA) and the Nucleus Accumbens is critical for the addiction process because lesions to this pathway eliminate addiction. It is a part of the brain.

<h3>What is the nucleus accumbens?</h3>

The nucleus accumbens refers to a part of the forebrain located in the hypothalamus.

The nucleus accumbens is an interface between motivation (i.e., stimuli) and the corresponding action (response).

The nucleus accumbens is fundamental in different responses such as, for example, rewards, stressful situations, drug behavior, etc.

What single feature is primarily responsible for the variation of climate in different parts of the world?
astraxan [27]

angle of incoming sunlight

Explanation:

The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.

  • Climate is simply an extended study of weather over a long period of time.
  • The elements of weather like temperature, pressure, rainfall all conditions climate.
  • The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
  • Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
  • The polar and temperate regions receive diffused sunlight because the sun is at an angle there.
