Answer:

The correct answer is - 19 ATP.

Explanation:

One molecule of dihydroxyacetone phosphate fully oxidizes and generate 19 molecules of ATP by the following stochiometry

Direct ATP- 2

ATP from NADH ( 5X3)= 15

A biologist studying a desert ecosystem observes that the population of a lizard species increases following a particularly hot,

bekas [8.4K]

Based on the description of events, being that the lizard population appears to increase as soon as the snake population decreases, it appears that the snakes prey on the lizards. This suggests that the snake is a keystone species. A keystone species is one that has a dramatic effect on maintaining the balance of an ecosystem. As soon as the snake population decreases, major changes occur to the ecosystem, such as the lizard population increasing.

Therefore, the answer is D: <span>The snake is a keystone species in the ecosystem.</span>

What do we call the process where part of the DNA is saved during replication?

Nataly_w [17]

Answer:

The process where part of the DNA is saved during replication is known as semi conservative replication.

Explanation:

During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid). When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus of a cell during the s stage of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.
