1. Cushing's syndrome is caused due to prolonged exposure to inappropriately high levels of the hormone cortisol.


It is a congenital deficiency of thyroid hormones and also called congenital hypothyroidism. It occur due to decreased activity of thyroid gland.

Hypothyroidism in adults is called myxoedema It can occur due to decreased as well as increased activity of thyroid gland.


Decreased activity of thryroid gland shown in this disease is more severe and occur after hypothyroidism of cretinism.


In this way, myxoedema can be considered the adult counterpart of cretinism.


It causes stunted physical and mental growth



It causes cutaneous and dermal swelling due to accumulation of fluid



3. Usually cell division occur after DNA replication. But in case of multinucleate cells such as of coenocytic/aseptate fungi, complete cell division does not occur after replication of DNA/chromosomes resulting into multinucleate condition.



Try to find the answers of rest of the questions by yourself.
