Answer:

I'd say C, The main different between cellulose, and starch is the function they preform in plants.

Explanation:

I've done some research to find that starch and cellulose do compose of different parts of the plant, and that starch repeats glucose units oriented in the same direction, while cellulose repeats glucose units 180° around the axis of the polymer backbone chain. Of course we know photosynthesis produces glucose, and oxygen from co2, light energy, and h20. Which means that they both have the same monomer. Since cellulose and starch are polymers of the monomer glucose, A can't be right. They are said to have the same size because the only difference is how the repeat of the glucose monomers are oriented differently so this does not exactly change its relative size, so B can't be right. Starch has alpha linkages while Cellulose has beta linkages. This means they have a different structure which can affect the function. Also, the function of cellulose is a Structural polysaccharide(cause it is part of the walls of the plant), while starch is a Storage polysaccharide (cause sugar=energy).

Imagine that a toxin is introduced to the body and inhibits the establishment of the proton gradient in the intermembrane space.

jarptica [38.1K]

Answer:

ATP synthase would be unable to produce ATP

Explanation:

ATP synthase depends on the proton gradient in the intermembrane space to enable it to produce ATP. As a consequence of this, the toxin will make it inactive. Oxidative phosphorylation is now inhibited in this case, as opposed to substrate-level phosphorylation.

Pyruvate is a product of glycolysis, and it will not be affected by a toxin. NADH is very important in the establishing of a proton gradient, so it is expected that it would be unable to be oxidized due to the toxin. Protons produced in the conversion of NADH to NAD+ actually establish the proton gradient. If the gradient is absent, NADH is then not likely to be oxidized.

Why do different individuals of the same species have different traits?

deff fn [24]

Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.

<h3>Variations</h3>

Organisms of the same species can have different traits due to a difference in their proteins.

Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.

Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.

In sexual reproduction two ________ sex cells come together to form a new individual.

Lelechka [254]

What happens when lakes are acidified?

Dima020 [189]

Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, crayfish and clam populations are the first to disappear, then various types of fish. Many types of plankton-minute organisms that form the basis of the lake's food chain-are also affected. As fish stocks dwindle, so do populations of loons and other water birds that feed on them. The lakes, however, do not become totally dead. Some life forms actually benefit from the increased acidity. Lake-bottom plants and mosses, for instance, thrive in acid lakes. So do blackfly larvae.
