The use or expression of different subsets of genes to manufacture proteins drives the specialization of distinctive cell types
elixir [45]

According to the research, the correct option is differentiation. The expression of different subsets of genes to manufacture proteins drives the specialization of distinctive cell types and is referred to as differentiation.

<h3>What is differentiation?</h3>

It is the process by which a cell becomes another more specialized cell type that will involve morphological variations in the composition of its membrane and are produced due to a reprogramming of its gene expression.

Evolutionarily it has remained a stable process, occurring as the morphological and physiological transformation of meristematic cells into adult tissues or specialization.

Therefore, we can conclude that according to the research, the correct option is differentiation. The expression of different subsets of genes to manufacture proteins drives the specialization of distinctive cell types and is referred to as differentiation.

SCIENCE QUESTION
alexandr1967 [171]

Answer:

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Explanation:

Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.

When does the exponential growth of a population stop?
Advocard [28]

Answer:

When the population reaches its carrying capacity.

Explanation:

As a population grows, there is more competition for resources which can limit a population. There are also natural disasters that can play a role too such as disease. Another factor that is part of carrying capacity is the size of the habitat. If there is no room, then the population cannot increase.
