Answer:
Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.
The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.
Answer:
the answer to this question is B i believe
Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
The correct answer is C. Desert.
Desert area is likely to experience large amount of natural erosion.
Erosion occurs depending with the movement of ice, water or wind over a surface whereby it is known to occur on downward slope reason being the force of gravity.
Some of the causes of erosion include; gravity, water, and burrowing animals.
Erosion is known to occur when water or wind moves over soil, rocks, or sediment. Sometimes natural erosion benefits because it helps to have fertile soil.
Explanation:
I would change its existing soil. some trees and shrubs thrive if you replace existing soil with certain minerals and fertilizers where you plant the Bush..
in my case, we have clay soil poor 4 most plants., b4 planting outside, put fertilized soil in the hole your planting 1st, then existing soil..
