Biology

TiliK225 [7]3 years ago
7 0

Answer:

slow change

Explanation:

If the change is slow they have time to adapt. An example of a fast change is human deforestation. With their habitat suddenly removed, the organisms living there will have to find new shelter and food fast. It's likely that they'll not even be able to find anything to survive off of and die, because organisms tend to have very specific needs. For example, pandas would go extinct if bamboo was eradicated.

Freshwater fish would not be able to adapt if it was suddenly dropped into salt water. They would die. An example of a slow change would be the slow addition of salt to freshwater. Fish that are better able to survive within higher levels of salinity will be more likely to reproduce. Slowly through reproduction a new type of fish suited to salt water may be developed over several generations.

What does it mean for an environment to be isotonic?(1 point)
HACTEHA [7]

A solution to be isotonic refers to b) The concentration of solute in the environment and the concentration inside the cell are at equilibrium.

  • Isotonic solution is the solution that have equal concentration of solute on both sides of the solution separated by a membrane.
  • If a cell is kept in an isotonic solution that means the concentration of the solute inside the cell is the same as that of the outside then the movement of solvent does not occur between the cell and the external environment.
  • The osmotic pressure inside the cell and outside the cell across the semipermeable membrane of the cell becomes the same due to equal concentration of the solute on each side.

0.9% normal saline is an example of isotonic solution.

In which molecule is most of the energy of glucose stored at the end Of glycosis
fredd [130]
<span>The answer is adenosine triphosphate (ATP). Glycolysis is the metabolic pathway of glucose degradation which products are 2 molecules of pyruvate, 2 molecules of NADH, 2 molecules of ATP, hydrogen ions, and water. The free energy that is released in this process is stored in the form of ATP and NADH. However, the energy stored in ATP is greater than the energy stored in NADH. So, at the end of glycolysis, the most of the energy of glucose is stored in ATP.</span>
