What three organelles work together to prevent a plant cell from bursting

when it has too much water

Answers

Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting.

The contractile vacuole and the cell wall work together to prevent a plant cell from bursting.

What is turgor pressure?

The pressure exerted by the presence of excess water on the insides of the plant cell is called the turgor pressure. It is maintained with the help of two organelles. These are the cell wall and the contractile vacuole.

The cell wall is the outermost covering of the plant cells. It provides structure and rigidity to the plant cell. When a plant cell is kept in a hypotonic solution, it swells by taking up water by osmosis. The cell wall is an enclosed structure which prevents it from bursting. This condition of the plant cell is called turgidity.

Also, the contractile vacuoles of the plant cell are able to pump out excess water from the water when it has become extremely turgid.

Therefore, the cell wall and contractile vacuoles work together to prevent the plant cell from bursting.

Answers

Answer:

The first and second hominids have a more recent common ancestor than the first and third hominids.

Explanation:

The similarity in DNA can definitely reveal us about common ancestry but it does not guarantee that the two species must be mating and reproducing. The best example to support this statement is that humans and chimpanzees  share a common ancestor and both have so much similarity in their DNA. The DNA of humans and chimpanzees is around 99% similar but still humans and chimpanzees cannot mate to produce off springs. Several attempts have been made in past to obtain fertile off springs by mating humans and chimpanzees but so far their mating has not produced any fertile off spring.

means that clear water is not

A. the density of the water
B. high specific heat capacity
C. the temperature of the water
D. ability to act as a universal solvent

Answers

Answer:

B

Explanation:

Ability of water to act as a universal solvent means that clear water is not necessarily clean water. Therefore, option (D) is correct.

What is clean water?

Clean, safe water is defined by the USGS as "water that won't hurt you if you come in touch with it." Although drinking water is often mentioned when discussing clean water, clean water is also crucial for all residential uses.

It is impossible to smell, taste, or even see the microscopic contaminants that pollute water, such as bacteria, viruses, and parasites. Therefore, just because your water is clear doesn't imply it's okay to drink.

Therefore,  due to the fact that water is a universal solvent, meaning that it is capable of dissolving a wide range of substances with relative ease clear water is not considered clean.

1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the

steps in the path below. Then, label each location with the system it represents. Finally, summarize very

briefly how the carbon atom got to that location.

Answers

Answer:

Yes.

Explanation:

Yes, everything made or modified by humans with the help of knowledge and education. Without knowledge it is impossible to made new things or modify it. Carbon move from atmosphere to the biosphere by the process of photosynthesis done by plants in order to produce their own food so for that reason the plants take carbondioxide from the atmosphere and change into food whereas in the breathing of organisms this carbon moves again to the atmosphere. Carbon also moves from atmosphere to hydrosphere by dissolved in ocean water and lakes and the volcanic eruption and acid rain causes exchange of carbon between atmosphere and geosphere.

What is the structure of DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

Deoxyribonucleic acid (DNA) is made up of the four nucleotides A, C, G, and T. These nucleotides are linked together by a backbone made up of alternating phosphate and deoxyribose sugar residues. The complementary pairs of these nitrogen-containing bases are governed by their capacity to generate hydrogen bonds.

DNA is located inside the nucleus, a specific region of the cell, in eukaryotic species.

Therefore, chromosomes are the name for this DNA that has been packed.
