ss7ja [257]3 years ago
4 0

Answer:

Epitopes.

Explanation:

Antigen: Antigens are foreign proteins that enter the host body through an infection. Antigens are generally high molecular weight proteins or polysaccharides. Viruses and bacteria contain antigen on their surface or inside the body.

Epitope: Epitope is the molecular region on the surface of the antigen which interacts with the antibody binding site on the antigen. Epitopes are capable of stimulating an immune response so, these are also known as antigenic determinants. Binding between the receptor and epitopes occurs when they both fit together like a puzzle, that event is necessary to activate B-cell production of antibodies.

Which statement best describes how artificial selection can decrease a population's biodiversity?
IrinaVladis [17]

The statement 'artificial selection decreases the rate of natural selection and change within a population' describes how artificial selection can decrease a population's biodiversity. It is a human-driven process.

<h3>Artificial selection</h3>

Artificial selection refers to the human-driven process by which different organisms (either plants or animals) are selected in order to combine desired features in offspring.

In artificial selection, organisms are mated (crossed) in order to select the progeny having desired phenotypic traits.

This process (artificial selection) leads to a decrease in natural genetic variation (biodiversity), which may have negative consequences in the successive rounds of selection.

Lunar phases are basically the different positions of the moon that we see throughout its whole cycle, from new moon to full moon, back to new moon. Eclipses, though are more rare phenomena. These occur when the sun, moon, and earth line up at a specific position.

Asteroids are usually dense bodies, with many different formations on their surface. They are also believed to be the largest source of precious metals on our planet.

Comets are bright clouds of gas surrounding a center nucleus that speed toward the sun and heat up at the same time. They contain dust, ice, carbon dioxide, and other gases. As the comet soars toward the sun, the radiation pushes dust particles back, forming the tail they are known for.

How are the plants in a desert ecosystem most likely to differ from the plants in a rain forest ecosystem?
erik [133]
Hey,

I believe this answer is A: The desert plants are likely to be better at retaining water.

Which they do, and they have to cause water is very scarce in the desert unlike the rain forest.

Desert plants likely to be larger is not proven and most plants can vary in size.

Narrower stems may have something to do with it but that goes back to they have to hold more water so this is incorrect.

Brighter flowers doesn't have anything to do with water consumption within a plant so this is incorrect as well.

Hope this helps!
