Experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patients.
Explanation:
Experiments are conducted on brain cells by first growing human embryonic stem cells in a Petri dish and then converting them to brain cells. later the Alzheimer’s disease was genetically engineered into those nerve cells through gene mutation.
When these cells are exposed to varying concentrations of salt solution, the cells with shrink or swell according to the concentration due to cellular osmosis.
The cells will undergo chemical changes due to this. The regeneration probabilities of nerve cells affected by Alzheimer’s disease can be studied by such experiments.
The answer is D. Jupiter is a gas giant meaning that it is composed of mostly gases such as hydrogen and helium. It does not have a solid surface.
Answer:
I think c
Explanation:
active transport uses energy from ATP which is not found in the nucleus. so we know it uses energy which is not it's own and ATP is not apart of the nucleus so that leaves c
<span>Transport of the water from the roots to the leaves is driven through the vascular tissue called xylem. Water gets absorbed from the soil by osmosis and it must cross several cell layers (filtration system) before entering the xylem. The method used in the upward movement of water through the xylem is determined by the cohesion-tension theory (capilarity+transpiration). The transport is passive and it occures thanks to the primary force that creates the capillary action (adhesion between the water and the surface of the xylem and cohesion between individual water molecules) movement of water. Transpiration is also an important factor in the upward water movement. Transpiration in leaves creates tension (differential pressure) and because of this tension, water is being pulled up from the roots into the leaves.</span>
<span>These organisms protect themselves from being seen from above or below with countershading. Countershading is when the top part of an animal's body is dark, and lighter underneath. This is one way some animals can protect themselves from predators. Countershading is also called Thayer's Law.</span>
