Answer:
Limiting factor
Explanation:
In order to control the growth of the population you use Limiting factor
Answer:
Pigmented snails: A_B_; albino snails: A_bb, aaB_, aabb
This is an example of recessive epistasis. In recessive epistasis, two recessive alleles mask expression of an allele at a different locus. The 9:7 ratio observed in this question is a special case of epistasis called duplicative recessive epistasis, which means the presence of either aa or bb was sufficient to mask expression of the other gene. In this case, if snails had two copies of either allele a or allele b, pigment production was suppressed, resulting in albino individuals.
The respiratory system is the set of organs, which allows breathing, that is to say, the gaseous exchanges between the body and the environment.
The respiratory system can be easily assimilated to a bunch of grapesThe main stem of this branch of grapes is the trachea. then divides into smaller ducts called bronchi. Next, it branches into even smaller branches called bronchioles.
The grapes themselves are the alveolar sacs that are branched with the bronchioles. (each grape is an alveolar sac, the functional unit of the respiratory system).
Biological difference between females and males.
