A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
Answer:
Explanation:A-
For Glomerular filtration rate, Increased blood volume and increased blood pressure will increase .
Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease.
B- decreases both blood flow and filtration pressure where as constricting the efferent arteriole decreases blood flow but increases filtration pressure
The fact that both can be altered allows independent regulation of both GFR and blood flow.
Answer:
The correct answer is option D. Osmosis
Explanation:
Osmosis the process in which high solute concentration molecule move to low concentration molecule through the semi-permeable membrane.
In the hypotonic solution, a cell get lysed due to solute movement into the cell whereas in a hypertonic solution cell shrink due to movement of solute out of the cell.
Thus, the correct answer is option D. Osmosis.
