Question

Curite a short note on
mammary and bastula​

Answer 1

☺ Good afternoon ☺

1)

mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring. Mammals get their name from the Latin word mamma, "breast". The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants

2)

The process of embryogenesis begins when an egg or ovum is fertilized by a sperm cell to form a zygote.

This zygote then undergoes mitotic division, a process that does not result in any significant growth but creates a multicellular cluster called a blastula. This process is referred to as cleavage. The blastula then develops a pore or a hole at one end, called a blastopore.
