What is a hypertonic solution? How does it affect a red blood cell?
What is a hypotonic solution? How does it affect a red blood cell?
Answer plz!

Answers

Answer 1

Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks

Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Answer 2

An isotonic solution is one wherein the solute concentration across the semipermeable membrane is the same resulting in an equilibrium state.

They do not shrink or swell in an isotonic saline solution, i.e., 0.9% w/v solution of sodium chloride

Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.

Now, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 2% w/v. The sodium chloride concentration of 2% w/v is greater than the RBC’s sodium content and hence the solution is hypertonic. This will result in shrinkage of the RBCs known as crenation

When a solution has a lower solute concentration than the solution present across the semipermeable membrane, it is known as a hypotonic solution. As a result, when a cell is placed in a hypotonic solution, an osmotic pressure gradient forces the solvent to move into the cell in order to attain equal solute

In another situation, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 0.1 % w/v. The sodium chloride concentration of 0.1% w/v is less than the RBC’s sodium content and hence hypotonic saline. This will result in swelling and eventually bursting of the RBCs which will result in the release of hemoglobin. This is known as hemolysis which is a very dangerous situation.

During photosynthesis, plants produce _____________ and oxygen from the _____________________________ of solar energy, water, and carbon dioxide

Answers

Answer:

During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.

Explanation:

Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Which of the following is a binocular cue for depth perception?.

Answers

Where is the picture ?

A binocular cue used to assess depth between two nearby objects is called retinal disparity.

What is the binocular cue for depth perception?

The pictures that both eyes focus on to create stereopsis, or the feeling of depth, is known as binocular depth cues. Using binoculars, one may see the world in three dimensions.

Binocular depth signals can be classified as either retinal disparity or convergence. Convergence centers on a single object while using both eyes.

A binocular cue used to assess depth between two nearby objects is called retinal disparity. It accomplishes this by contrasting the various pictures from the two retinas. Because the distance between each eye is typically around two and a half inches, each eye sees different pictures.

Therefore, the retinal disparity is a binocular cue for depth perception.

What arctic animals will climate change affect? How will it affect these animals? (Site 1).

Answers

Answer: Narwhals, polar bears, and walruses will be affected the most.

Explanation:

Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.

Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.

Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?

Answers

Answer:

English is not my native language so sry if there's any grammaticaly mistake

Explanation:

cuz it changes its shape and forme u got that?!

Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

What do you mean by Lac repressor?

Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.

When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.

Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
