Which endocrine gland is responsible for the release of a hormone that stimulates T-cell development and proper immune response
Mama L [17]

Answer:

The correct answer would be d. thymus.

The thymus is a specialized lymphoid organ of an immune system.

It serves as the site for training and maturation of T-lymphocytes or T cells.  

It is composed two identical lobes each containing outer region termed as cortex and inner region termed as medulla.

T-cells are first trained and selected in the cortex region via positive selection. In this, T cells which are able to bind to foreign antigens are selected and rest are degraded.

The selected T cells then move in the medulla region where they are selected by negative selection. In this, the T cells which binds to self-antigens are degraded and rest survive to become functional T cells.

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance​
ser-zykov [4K]

<u>What we already know:</u>

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

<em>So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex</em>.<em> That means that the gene codes for more than just the sex. </em>

<u>Building on that knowledge: </u>

<em>Sex-Related Inheritance</em> that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas <em>Non-Sex-Related Inheritance</em> is carried on the other thirty chromosomes that the individual also carries.

<em>Sex-Related</em> inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

<u>Vocabulary:</u>

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
