The thin, yellowish milk secreted in the few days right after birth is rich in antibodies and immune system cells. Group of answ
Damm [24]

Answer: The statement is TRUE.

Explanation:

The thin, yellowish milk which may appear at any time from late pregnancy to few days right after birth is known as Colostrum milk.

During pregnancy, progesterone and oestrogen cause the milk glands to develop in the mother's breast. Immediately after birth, the anterior lobe of the pituitary releases a hormone, prolactin, which stimulates milk production. When the baby suckles at the mother's nipples, the milk flows out.

This first yellowish milk known as colostrum, contains all the essential nutrients that a newly born baby needs. It also provides antibodies and immune cells that protect the infant from disease. The milk is rich in protein and fats than normal milk. It is the first immune system defense they receive after birth. Therefore the above statement about the first thin yellowish milk is TRUE.

Why do viruses need hosts to reproduce
Olin [163]
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the lytic phase: new viruses are formed, self-assemble, and burst out of the host cell, killing the cell and going on to infect other cells. The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly 200 nanometers
