Answer:
Researchers found that chronic exposure to a stress hormone causes modifications to DNA in the brains of mice, prompting changes in gene expression. The new finding provides clues into how chronic stress might affect human behavior.
Because in that way we keep thinking about them. How can you forget something when you're thinking about it?!
The experimental group is the group you change from the normal. the fertilizer group is experimental
Answer: Transition forest
The mixture of
wildlife species in different ranges or ecosystem is known as transition
forest. The Shenandoah national park has multiple
trends such as natural regeneration of forests, forest plantation, adsoption of
agroforestry to continuing deforestation. This manifestation indicates that
there is a turnaround in land use from a period of net forest area gained to
net forest loss.
The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
