Introduction:
Adrenal gland comprises of adrenal cortex and the adrenal medulla. These secrete hormones which have different functionalities. Adrenal cortex is made of epithelial cells and adrenal medulla is made of neural cells. Zona glomerulosa, Zona fasciculate and zona reticularis are the three layers of adrenal cortex.
The cortex part of the adrenal gland is responsible for secretion of mineralocorticoids, glucocorticoids, and sex hormones. It secretes mineralocorticoids and glucocorticoids which helps regulate stress response. Adrenal medulla secretes two hormones i.e. adrenaline (epinephrine) and nor-adrenaline (nor-epinephrine). Known as adrenaline, Epinephrine is an active sympathomimetic hormone which stimulates the beta- and alpha-adrenergic systems.

Answer to Problem 1E
Solution:
Among the options given, the correct answer is option (d) medulla
Explanation of Solution
Explanation/justification for the correct answer:
The correct answer is option (d) Medulla. Zona glomerulosa, Zona fasciculate and zona reticularis are the three layers of adrenal cortex. Androgens, cortisol and aldosterone hormones are secreted by this. Another part of the adrenal gland which is made of neural cells is the adrenal medulla. This secretes hormones like epinephrine and nor-epinephrine. So, the option d. Medulla is correct answer.
Explanation for incorrect answer:
Option (a) Zona Reticularis. This is a layer of the adrenal cortex. The cortex part of the adrenal gland is responsible for secretion of stress response regulating hormones and sex hormones. Zona reticularis is the layer where Androgens are produced. Hence, it is incorrect.
Option (b) Zona fasciculate. This is a layer of the adrenal cortex. The cortex part of the adrenal gland is responsible for secretion of stress response regulating hormones and sex hormones. Zona fasciculate is the layer where glucocorticoids like cortisol are produced. Hence, it is incorrect.
Option (c) Zona glomerulosa. This is a layer of the adrenal cortex. The cortex part of the adrenal gland is responsible for the secretion of stress response regulating hormones and sex hormones. Zona glomerulosa is the layer where aldosterone is mainly produced. Hence, it is incorrect.
It is from the medulla that Epinephrine is released.

- Linkage in common bean Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population…arrow_forwardAlleles at the P locus control seed color.
