Answer:
A constant allele frequency is maintained by populations in absence of natural selection as both the alleles for the trait impart equal survival advantage (adaptive) to the individuals under the prevailing conditions.
Explanation:
A population maintains constant allele frequencies in absence of evolutionary forces such as natural selection. This occurs when the existing allele frequencies of a gene are adaptive to the individuals. Both the alleles for a trait should be equally beneficial in terms of survival and reproductive success of the individuals under the given conditions. Therefore, both the alleles are maintained with existing frequencies.

Answer:
B) the venae cavae.
Explanation:
The lymphatic system is an organ system that consists of a network of lymphoid tissues, lymphatic vessels and organs, which perform functions such as removal of toxins and unwanted materials, as well as production of immune cells that helps primarily in fighting against infection.
Lymphatic vessels, the spleen, lymph nodes, and lymph are all part of the lymphatic system.The venae cavae are two large vessels that empty deoxygenated blood received from all parts of the body into the right atrium. They are not part of the lymphatic system.
