In the mouse model of malaria, the researchers injected Plasmodium-infected human red blood cells into the mice because the Plasmodium species had surface ligand proteins that bound only to cell membrane proteins of human red blood cells. Assume that the researchers noticed that some of the parasites no longer infected human red blood cells but instead infected mouse red blood cells. Predict the most likely cause of this change in the host specificity of the parasites. Plasmodium reproduces both sexually in the host vertebrate and asexually in mosquitoes. The researchers claim that the Plasmodium organisms that infect the two different types of red blood cells are likely to evolve into two separate species of Plasmodium. Based on the biological species concept, provide reasoning that would support the researchers’ claim.

Answers

Answer 1
There is a mutation in the în the genes coding the ligand. They will evolv3 separately in two host species proving the researchers right.

Explanation:

Suppose 10,000 units of energy are available at the level of the plants . How many energy units would be passed from the frog to the snake ? A 100 units 10 units C 1,000 units D 10,000 units

Answers

Answer:

10 Units

Explanation:

If you makes an energy pyramid the energy from the plant to the organisms would be

plant (10,000) --> grasshopper (1000) --> frog (100) --> snake (10) --> eagle (1)

If 10,000 units of energy are available at the level of the plants, then one can estimate that the amount of energy available at the level of the frog is 1000, and then at the level of the snake it is 100 kJ, which is in option A.

The transfer of energy between trophic levels is known as energy flow, and in an ecosystem, the primary producers, such as plants, are at the first trophic level, followed by the primary consumers, such as herbivores like the frog, at the second trophic level. The secondary consumers, such as predators like the snake, occupy the third trophic level, as here the third one is the snake, and it will get 10% of the frog.

Which quality of lipids does it demonstrate?

inability to store energy
ability to form chains of nucleotides
inability to break down in water
ability to provide structural support

Answers

Answer:

I thinks its d but not sure

Explanation:

Lipids are macromolecules composed of fatty acids. The diagram represents the inability of the lipids to break in the water. Thus, option c is correct.

What are lipids?

Lipids are said to be polymers as they are large molecules made of the monomers of the fatty acid chains and glycerol bonded together by chemical bonds. They include oils, fats, steroids, waxes, hormones, phospholipids, etc.

They are energy storage molecules along with carbohydrates and act as messengers in the form of hormones. They store energy in fat cells (adipose) for a longer period of time. They make the component of the cell membrane, blood cells, and cholesterol.

They are soluble in an organic solvent but not in water as it is a non-polar compounds with hydrophobicity and hydrophilicity. They are insoluble and remain intact in the water molecule.

Therefore, option c. the lipids do not break in the water.
