For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration grad
Vlad [161]

Answer:

The lack of ATP would slow nerve responses to generate an action potential

Explanation:

Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

Which of these are true regarding eukaryotes? (choose all that apply)
OleMash [197]

Answer:

b. During replication there is both a leading strand and a lagging strand .

c. Each replication bubble has two replication forks.

Explanation:

Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.

The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.

To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.

The discontinuously replicated strand is lagging strand while the other one is the leading strand.

DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.

The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.

Scientific information that is hundreds of years old is fact and does not change.
notsponge [240]
False

Facts are simple observations of the world, and they do not change over time until unless the theory was changed due to different research . Theories are hypotheses about what these facts mean, or how they should be understood, and they could change over time..
