Answers

Inflammation, your skin, and macrophages are all part of the body's general immune system response to a pathogen.
General or non-specific immune response include the cells and mechanisms for defending the host from infection, but those mechanisms are not long-lasting. It includes anatomical barriers (like skin or mucose membranes),recruitment of immune cells to sites of infection, removal of pathogens by white blood cells (like macrophages)…

Biomolecules can be classified as lipids on the basis of

Answers

The question is incomplete as it does not have the options which are:

A) the presence of many hydroxyl groups and at least one carbonyl group.

B) the presence of at least one amine group and one carboxylic acid group on each molecule.

C) the physical properties of odor, color, and melting point within certain guidelines.

D) a common structure consisting of long hydrocarbon chains.

E) the physical property of solubility in nonpolar organic solvents.

Answer:

E) the physical property of solubility in nonpolar organic solvents.

Explanation:

Lipids are one of the biomolecules which are involved in the formation of various other complex molecules in the body. The structure of lipids contains a very long hydrocarbon chain which provides hydrophobic to the compound.

Since they are hydrophobic therefore cannot form bonds with the water and thus repel water. This molecule is therefore considered a non-polar molecule. These non-polar molecules are soluble in the non-polar organic solvents only.

Thus, Option-E is the correct answer.

A relationship in which one species consumes and the other is killed is known aspredation.
parasitism.
commensalism.
mutualism.

Answers

Predation

It can be explained in that way or also called Predatory/prey relationships.
Parasitism is when one is benefited and the other harmed (ie leech and human)
Commensalism is when one is benefited and the other not affected (Tree frog and rainforest tree)
Mutualism is when both are benefited (Bee eats honey and Flower is pollinated).

A relationship in which one species consumes and the other is killed is known as predation.
