Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.

Answer:
The correct answer is b. Neutrophils
Explanation:
Neutrophils are the cells that first reach to the infection side and kills the bacteria. Neutrophils comprises most part of WBCs approximately 50-70% of total WBCs. Neutrophils kills the foreign bacteria by engulfing them and this process is called phagocytosis.
The engulfed bacteria is called phagosome and phagosome then fuse with lysosome making phagolysosome. Now fused lysosome secrete lytic enzymes like proteases, lipases and glycosidases which kills the engulfed bacteria by digesting them.
So neutrophils will be the first cells migrates to prevent bacterial infection in the hand of 20 year old boy who shoots his hand with nail gun.
