describes lipids in water

Answers

Answer:

Ok

Explanation:

Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped

What is the function of the cytoplasm?​

Answers

Answer:

Thay are:

1. The cytoplasm function to support and suspend arganelles and cellular molecules.

2. The cytoplasm helps to move materials,such as hormones, around the cell and also dissolves cellular waste.

Answer:

Cytoplasm Function

One of the major functions of cytoplasm is to enable cells to maintain their turgidity, which enables the cells to hold their shape. Other functions of cytoplasm are as follows:

The jelly-like fluid of the cytoplasm is composed of salt and water and is present within the membrane of the cells and embeds all of the parts of the cells and organelles.The cytoplasm is home to many activities of the cell as it contains molecules, enzymes that are crucial in the break down of the waste.The cytoplasm also assists in metabolic activities.Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells, without cytoplasm, would deflate and substances will not permeate easily from one to the other organelle.A part of the cytoplasm, the cytosol has no organelles. Rather, the cytosol is enclosed by matrix boundaries that fill up the cell section which does not hold the organelles.

The whole cellular content of a living cell is called protoplasm. The cytoplasm, nucleus and all other living components of the cell together make up the protoplasm of a cell.

The cell walls of a plant consist mostly of cellulose, a carbohydrate, which provides a strong structure. The cell membrane gets its structure primarily from lipids, and embedded proteins allow for material transport.

Which of the following elements would be found in the LOWEST amounts in both the cell wall and cell membrane?

Answers

Answer:

The answer is Sodium (Na+)

Explanation: The cell wall of the plant cells is composed mostly of cellulose, which is a polysaccharide composed mostly of carbon, hydrogen and oxygen, and it has a linear and complex configuration. On the other hand, the cell membrane is composed of phospholipids, in the configuration of lipid bilayer. Phospholipids are molecules that have a polar head (where phosphorus is found) and a hydrophobic (lipid) tail. Carbon and hydrogen are also found in non-polar or hydrophobic tails. Sodium on the other hand is an Ion (Na +) that is mainly dissolved in water, so it is expected to find it mostly in the lumen or outside the cell. Sodium plays an important role in the transport of some substances through the cell membrane, but their amounts cannot be very high, because of being very concentrated, this can cause plasmolysis or cell destruction

How would the loss of predators contribute to deforestation in the
jungle?

Answers

Answer:

Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.

hope this is a decent answer :)
