Indicate whether below is true/false.
1. mammary glands are specialized for milk and hormone production.
2. breasts contain areolar connective tissue but little dispose tissue.
3. alveolar glands occur in lobes of mammary glands.

1. True

2. True

3. False

Explanation:

Mammary glands are made up of glandular tissue. These are meant for the secretion of milk after the newborn birth. The milk ejection is done by different hormones, especially by progesterone and prolactin.

Glandular tissue acts as both exocrine and endocrine glands. The mammary glands are a suitable example as it secretes milk which is an exocrine secretion.  The hormone progesterone and prolactin released from the mammary gland are endocrine secretions.

The mammary glands consist of a sac-like structure called alveoli.

These are group alveoli form grape-like appearance called lobules.

The alveolar sacs contain sweat glands. These are the modified sweat glands that secrete milk. It is made up of fibrous connective tissue.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
