b)

The adrenal glands secrete the following hormones:mineralocorticoids,glucocorticoids , sexo steroid noradrenaline and adrenaline

The pancreas secretes insulin and glucagon

the stomach and duodenum secrete hormones related to digestion like gastrin

The testicles secrete testosterone

c)

Adrenalin is secreted during the fight or flight response, same goes for noradrenalin, mineralocorticoids are secreted when the blood pressure decreases, glucocorticoids are secreted during stress, sexo steroids are secreted during puberty

Insulin is secreted when blood sugar levels are high. Glucagon is secreted when blood sugar levels are low.

Testosterone is secreted during puberty

The hormones secreted by the stomach and duodenum are secreted during digestion.

d)Adrenaline increases the heart rate, and blood pressure. Glucocorticoids increase the blood sugar levels. Sexo steroids determine secondary sexual characteristics. Noradrenaline causes vasoconstriction. Mineralocorticoids increase the blood volume.

Glucagon increases the blood sugar level. Insulin decreases the blood sugar level.

Testosterone determines secondary sexual characteristics. The hormones secreted by the stomach and duodenum aid in digestion.

Q3. Orange juice has ample amount of simple sugars (such as fructose, glucose), which are monosaccharides. So option A. Benedict test is required here.

Q4. Incomplete information provided

Q5. You need a certain kind of food that is rich in protein and simultaneously lacks fats. Here, skimmed milk is relevant - fat has been removed from the milk although protein is still present.
