Answer:

Mutation
If organisms choose a mate for a specific reason
People moving into or out of an area

The answer to the above question is Fatty acids.

<h3>What are Fatty acids?</h3>

A fatty acid is a carboxylic acid with an aliphatic chain that is either saturated or unsaturated. This definition applies to chemistry, particularly biochemistry. The majority of naturally occurring fatty acids have an unbranched chain with 4 to 28 carbon atoms, which is an even number. In some species, like microalgae, fatty acids make up a significant portion of the lipids (up to 70% by weight), but in other organisms, they are present as one of the three main types of esters: triglycerides, phospholipids, or cholesteryl esters rather than in their solo form. Fatty acids are crucial nutritional sources of energy for animals in any of these forms, as well as crucial cellular building blocks.

A cell has a defect in its receptor for growth factors, preventing growth factors from attaching to and signalling the cell. Bas

morpeh [17]

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.

Why are all of the pigments not visible in a typical leaf?

igor_vitrenko [27]

The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.

Explanation:

There are mainly three types of key pigments in photosynthesis. These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.

The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
