Answer 1

Q - The endocrine system -

-All the given choices are correct

Ans - All the given choices are correct

EXPLANATION - Endocrine system is a system of endocrine glands which secrete chemical called hormones directly into lymph or venous blood for transport to target tissues generally located away from the site of secretion.

Q - Not all hormones take the same amount of time to produce an effect-

-False

Ans - TRUE

EXPLANATION - Hormones are transported to the target tissue through blood .Time taken in producing an effect is variable.

Q - Epinephrine is hydrophobic -

-True

- False

Ans - FALSE

EXPLANATION - Amino acid derivatives such as epinephrine are water soluble(HYDROPHILIC).

Steroid hormones are Hydrophobic.

Q - Both __________and __________ produce hormones.

-None of the given choices.

-Cerebellum, pancreas

-Pineal gland ,Sweat glands

-Bone ,Adipose tissues

Ans - None of the given choices

Cerebellum, Sweat gland (exocrine gland) ,Bone and Adipose tissues does not produce any hormone. So, none of the above pair is correct.

Q - Hormone producing organs are-

-Slivary glands

-Adrenal gland

-Thyroid gland

-Pancreas

Ans - Hormone producing organs are Adrenal gland, Thyroid gland and Pancreas.

EXPLANATION -

* Slivary gland is an example of exocrine gland that do not produce any hormone .

* Adrenal Gland : These are paired glands located at the anterior part of kidneys.These glands secretes many kinds of hormones like Aldosterone and Cortisol.

*Thyroid Gland : Thyroid is the largest endocrine gland.Thyroxine (T4) ,tri-iodothyronine (T3) and thyrocalcitonin (TCT) are produced by thyroid gland.

*Pancreas : Pancreas is a composite (heterocrine gland) .It act as both endocrine and exocrine gland.Glucagon and Insulins are secreted by pancreas.
