Which of the following is a type of lipid or composed of lipids?

1 answer:

7 0

The answers are all accurate. Lipids, or substances consisting of lipids, include triglycerides, plasma membranes, cholesterol, and oils.

Lipids are substances that contain lipids, such as glycerides, plasma membranes, cholesterol, and oils.

Glycerol is esterified into three fatty acid chains with distinct lengths and contents to form lipid molecules known as triglycerides. Saturated or unsaturated fatty acid chains are the two types.

The phospholipid bilayers that makeup plasma membranes are lipids. Glycerol, a head with a phosphate connection, and two fatty acid tails make up a phospholipid. Hydrophobic interiors and hydrophilic exteriors characterize phospholipids.

In the blood, a lipid called cholesterol is carried by proteins called lipoproteins throughout the body.

Liquid lipids exist in the form of oils. Lipids share a similar chemical composition. They contain glycerol esters attached to fatty acids in the form of long-chain molecules.

As a result, we can conclude that every response is correct. Triglycerides, cholesterol, plasma membranes, and oils are lipids or lipid-containing compounds.

How do aquatic factors affect the distribution of aquatic life. Include biotic and abiotic factors. Please help. Thanks

Kisachek [45]

Answer:

In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.

Some of the abiotic factors which affect the distribution of the aquatic life are:

Amount of light: The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.

Water flow rate: Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.

Temperature: Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.

Some of the biotic factors which affect the distribution of the aquatic life are:

Predators: If there are more number of predators than the preys, then the prey diversity will have a serious threat.

Aquatic plants: There will be more aquatic biodiversity in the areas where there will be more aquatic plants.

DanielleElmas [232]

The answer is D) Electrons are transferred to ferredoxin.

Photosystem I is the part of photosynthetic light reactions. It is membrane protein complex which uses light energy to transfer electron from plastocyanin to ferredoxin.

In "simple columnar epithelium," which word describes cell shape and which word describes the number of cell layers?

dolphi86 [110]

Answer:columnar describes cell shape.

Simple describe the number of layers

Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.

Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.

The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.

Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.

Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.
