Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>

Answer:
Species evolve over time as a result of
- the potential for a species' population to increase.
- genetic differences in offspring due to mutation and the recombination of genes.
- a limited supply of necessary resources.
- selection by the environment of offspring that are best able to survive and reproduce.
Explanation:
NOT random mating within a species
Answer:
The correct answer will be option E (none of these lists are correct).
Explanation:
Common lymphoid progenitor cells or CLP are the cells which produces all types of lymphocytes in body which are T-lineage cells, B-lineage cells, natural killer (NK) cells and dendrite cells.
CLP differentiates into lymphocytes: CLP
↓
lymphoblast
↓
pro-lymphocyte
The pro-lymphocytes divides to form T-cell, B-cell, natural killer (NK) cells and dendrite cells.
Thus, option E none of these lists are correct is the correct answer.
Answer:
Over all growth and development cycle
Explanation:
<em>C. elegans,</em> due to its manageability, nervous system, muscle, skin gut and reproductive cycle makes it an ideal model. These nematodes are similar to human systems and lot of the research found can be applied to humans and medicine.
Apoptosis is the programmed cell death and this can be for many reasons such as repair, replace or removal of old or damaged cells. This groundbreaking research has captured the attention of scientist over the decades and many new findings are continuing to evolve.
Some phenotypes that are important in studying apoptosis are: Stress response, growth and development, tumor formation/regeneration and wound healing.
