For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration gradients such that a signal can be propagated down the axon of a neuron without the necessity of ATP. The system could have worked the opposite way. The neuron could have used ATP to move ions across when a signal was being propagated and then allow natural diffusion to return the ions to their respective sides of the membrane. What advantage does the organism have using ATP up front

Answers

Answer 1

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.

A genome-wide association study involves searching the genomes of many people in order to find genetic variations associated with common diseases such as cancer, asthma, and diabetes. These studies are possible because of computer databases that allow researchers to compare the genomes of people who do not have a particular condition with the genomes of people who have the condition. In order to do this type of testing, researchers need blood samples or cheek swabs from people. Obtaining these samples is necessary because blood and cheek cells contain___________

Why are recessive traits shown less than dominant traits?

Answers

Answer:

Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.

Question 1:
C. Nervous

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate B because we aren’t using the integumentary system (skin, hair).
— We can eliminate D because the respiratory doesn’t instruct any systems, it just keeps them going.

Question 2:
D. Immune, Integumentary, Circulatory

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate C because we aren’t using the muscular system (muscles).
— We can eliminate B because we aren’t using the skeletal system (bones).

Question 3:
D. None of these

BECAUSE
— We can eliminate A and C because we need the integumentary system to maintain body temperature (the integumentary system uses skin to regulate body temperature).
— We can eliminate B because we need the muscular system to maintain body temperature (the muscular system uses its ability to contract muscles to create heat).

Question 4:
B. Digestive, Circulatory, Excretory

BECAUSE
— We can eliminate A and C because we need the excretory system to digest and maintain homeostasis (to prevent damage to the body).
— We can eliminate D because B is our answer.

Question 5:
B. Reproductive, Nervous, Endocrine, Circulatory

BECAUSE
— We can immediately eliminate A, C, and D because we need the excretory system (hormones) to reproduce.

DNA polymerase only travels in the__________to________direction.

Answer:

Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.
