Describe the fate of cells with or without cell walls in various "tonic" solutions (hypertonic, hypotonic, etc.).
hichkok12 [17]

Answer:

In hypertonic solutions, the cells will shrink and in hypotonic solutions the cells will fill up

Cells with cell walls will be able to control their tonicity better than cells without cell walls.

Explanation:

Cells with cell walls

  • In a hypertonic solution (high solute concentration), water will flow out of the cell into the solution until equilibrium is reached. If the solution has a high concentration of solute the cell may undergo<u> plasmolysis where the plasma membrane detaches from the cell wall.</u>
  • In a hypotonic solution: Water will flow into the cell because it has a higher solute concentration compared to the solution. This will continue until the cell is <u>turgid</u>. If more water continues to enter the cell, the cell is at risk of bursting, this takes a while because the cell wall will withstand the pressure.

Cells without cell walls

  • In a hypertonic solution: Water will diffuse out of the cell, however there is no cell wall so cell is in danger of shrinking and dying.
  • In hypotonic solution: Water will diffuse into cell,the cell will become turgid and if water keeps moving in the cell will burst because it has no cell wall to resist the pressure.

kobusy [5.1K]

Volume of the cell increases more than its surface area of the cell.

<h2>What is the relationship between the surface area and the volume?</h2>

The relationship between the surface area and the volume of a cell is that when a cell grows bigger, its internal volume enlarges and the cell membrane tends to expands but more increase occur in volume as compared to the surface area which results in the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

The surface area and the volume ratio decreases as the cell increases in size. Cells are often flattened instead of cube-shaped because a flattened cell has greater surface area than a cube-shaped cell.

During _______________, the excitement peaks as breathing, pulse, and blood pressure rates continue to increase. the plateau pha
SashulF [63]
I believe the answer is the Plateau phase of the sexual response cycle. The sexual response cycle has four stages of sexual responding described by Maters and Johnson; that is the excitement, plateau, orgasm, resolution phases. During the excitement phase, the genital areas become engorged with blood. During the orgasm phase, there are muscle contractions all over the body, further increasing breathing, pulse and blood pressure rates; and during resolution phase the body gradually returns to its unaroused state as the engorged genital blood vessels release accumulated blood.

kakasveta [241]

The human population has changed since it first appeared on earth as The b. population has generally increased, and at rates that have varied over time.

Humans, as well as other populations, have changed since their appearance on earth. Some populations became extinct as they were not able to cope with the environmental changes whereas other became more adaptable and increased in number over time.

The human population has also increased with the passage of time. However, the increase in the rate of the human population was not a stable one. At some times in the past, the population number declined due to environmental factors such as the eruption of a disease etc.

However, with the passage of time, humans have managed to adapt themselves to the changing environmental conditions and their population is increasing rapidly.

Although a part of your question is missing, you might be referring to this question:

The human population has changed in ways that are similar to other populations. How has the human population changed since it first appeared on earth?

a. The population has generally increased at a relatively constant rate

b. the population has generally increased, and at rates that have varied over time

c. The population increases rapidly until it reaches carrying capacity, where it has remained for thousands of years

d. The population increases rapidly until it reaches carrying capacity, and then decreased at a constant rate
