After their creation, lymphocytes migrate to other immune system organs, such as the where they develop more fully and are stored until needed.

Answer;

Thymus.

After their creation, lymphocytes migrate to other immune system organs, such as the thymus, where they develop more fully and are stored until needed.

Explanation;

The thymus is a specialized primary lymphoid organ of the immune system where the maturation of T-cells takes place.

T lymphocytes are formed from a common lymphoid progenitor in the bone marrow that also gives rise to B lymphocytes.

The progeny used to give rise to T cells leave the bone marrow and migrate to the Thymus where maturation of the T cells take place.

c. genetic engineering

explanation:

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
