HACTEHA [7]3 years ago
4 0

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.

Explain what would happen if water did not expand when freezing. How would this impact aquatic life?
Lapatulllka [165]

Explanation:

If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.

The death of the corpus luteum results in the formation of __________.
HACTEHA [7]

Answer: The correct answer would be corpus albicans.

Explanation:

After ovulation, the ovarian follicle converts into corpus hemorrhagicum. After some time, it converts into a temporary endocrine structure termed as corpus luteum. It maintains high levels of progesterone which is necessary for maintenance of uterus lining.

However, in absence of pregnancy or fertilisation, the corpus luteum starts degrading and convert into the structure termed as corpus albicans.
