Olenka [21]

This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution  would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.

Explanation:

The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.

A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.

A solution having lower concentration of solute than the cell cytoplasm is called the  hypotonic solution.

The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.

A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.

A cell placed in hypotonic solution  will undergo endosmosis of water  so it will gain water and its mass will increase.

pochemuha
In fetal circulation, the ductus venosus bypasses the liver and the ductus arteriousus bypasses the lungs. Ductus arteriosus also called ductus botalli is a blood vessel connecting the main pulmonary artery to the  proximal ascending aorta. It does allow most of the blood from right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Ductus venosus on the hand allows oxygenated blood from the placenta to bypass the liver.

  • A form of dementia that progresses is Alzheimer's disease. A condition that adversely impacts memory, thinking, and behavior is referred to as dementia. The modifications make daily life more difficult.  There are numerous possible causes of dementia, including diseases and brain traumas.  Sometimes there is no known cause. The condition is typically diagnosed in patients over the age of 65.

  • Alzheimer's disease is typically described as having an "early onset" or "younger onset" if it is discovered earlier. Alzheimer's has no known cure, but there are medications that can halt the disease's growth. Alzheimer's disease is a brain ailment that gradually impairs thinking and memory abilities as well as the capacity to do even the most basic tasks.  Additionally, psychological and behavioral changes are common in people with Alzheimer's.
