The solute potential of a plant cell is -10 bar, and its pressure potential is 3. The plant cell is placed into a solution with
Nesterboy [21]

The water potential of the cell would be -7 bar and thus, water will move from the cell to the surrounding solution.

Recall that:

Water potential = pressure potential + solute potential

For the plant cell, solute potential = -10, pressure potential = 3

Water potential of the cell = 3-10

                                          = -7 bar

The water potential of the cell is -7 bar while that of the surrounding solution is -10 bar. Thus, the cell has a higher water potential than the surrounding solution.

Recall that water usually moves from the region of high to the region of low water potential. Therefore, water will move from the cell to the surrounding solution.

Describe two events that are common to both mitosis and meiosis that ensure the resulting daughter cells inherit the appropriate
Diano4ka-milaya [45]
During Mitosis and Meiosis, the both cells undergo a DNA replication process which ensures that the cells produced will have the same characteristics as the parent cell. The chromosomes then gather on the center then this is where the two cells divulge. Meiosis produces four haploids and Mitosis produces two daughter cells.

You Asked ➤ Which of the following processes begins when a star enters the main sequence?

↴ OUR CHOICES ↴

A: Nuclear fission

B: Nuclear fusion

C: Condensation of a nebula

D: Appearance of a supernova

------------------------------------------------------------------------------------

Answer ➤ B: Nuclear fusion

Explanation: When a star begins the process of being created, it is hot and dense. Really hot and dense! It begins to start fusing with helium which is the start of its main sequence called nuclear fusion.

I hope this answer is helpful to you, but please let me know if you have any other questions regarding it.
