2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr
atroni [7]

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

             NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

         Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

              That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.

1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are solub
boyakko [2]

Answer:

The correct model is D.

Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.

Explanation:

A water molecule is composed of one atom of oxygen and two atoms of hydrogen.

A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.

The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

Ryan hears a loud noise and quickly turns his eyes sideways in the direction of the sound. To accomplish this action he must use
maksim [4K]

Answer:

The correct answer is lateral rectus muscles.

Explanation:

To see what is happening in his side, or what originated the loud noise, Ryan has to use his lateral rectus muscle. Lateral rectus is one of the five extra ocular muscles that help in movement of the eye balls and help to see what is happening in and around us. It is mostly responsible for abduction, i.e. the movement of the eye balls away from the center line of the body. Defect in this muscle can result in sixth nerve palsy.

How is self-pollination similar to cross-pollination?
WINSTONCH [101]

Self-pollination occurs when the pollen from anther is deposited on the stigma of the same flower. Because cross-pollination allows for more genetic diversity, plants have developed many ways to avoid self-pollination.
