Answer:

trapping microorganisms

Explanation:

The primary role of the lymphatic system is to transport lymph through the body. Lymph is a fluid that contains white blood cells that fight with infection. Besides this immune function, lymphatic system has a role in fat and vitamin absorption and transportation.

Lymphatic system consists of vessels similar to blood vessels and nodes where the lymph is filtered. Lymph capillaries are closed on one side, so lymph does not circulate, but only drains to reach veins. In lymphatic system there is no such thing as a pump (only lymphatic vessels and lymph nodes).

Alja [10]

Answer:

1. 1/2

2. 1/2

3. 1/4

Explanation:

Let the allele for freckles be A or a while that of dimples be B or b.

A person without freckles but heterozygous for dimples = aaBb

A person who has freckles (whose mother has no freckles) but no dimples = Aabb

aaBb x Aabb

Offspring

4 AaBb - freckled and dimpled

4 Aabb - freckled and non dimpled

4 aaBb - non freckled and dimpled

4 aabb - non freckled and non dimpled

1. Probability that the parents will have a dimpled child = 8/16 or 1/2

2. Probability that they will have a child with freckles = 8/16 or 1/2

3. Probability that they will have a child with freckles and dimples = 4/16 or 1/4

Lerok [7]

Sterilization of animals reduces the level of circulating reproductive hormones leading to increased longevity, typically due to reduce cancer mortality. The primary aim of animal sterilization is avoiding overpopulation, but this increased longevity could be an added benefit for an individual animal.
