Answer:

The pituitary gland plays an important role in puberty and growth.

Epinephrine triggering the fight or flight response is produced by the adrenal glands which sit on top of the kidneys.

When hormone concentrations are high, the gland will produce negative feedback of the hormone.

Hope that helps.

Answer:

Per James Madison HS

Explanation:

Hormones

endocrine

pituitary

adrenal

less

prostaglandins

thyroid

Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.

What is an example of a stimulus and a response that humans exhibit? Can a similar behavior be seen in any other organisms?
Sedaia [141]
Common examples of this would be if you place your hand in extremely warm or cold water, and an immediate response of pulling out of the water or any fluid, is an example of this extreme response, other responses are what is done in everyday, like being thirsty or hungry etc.

These behaviours are shared by all organisms even the most simple ones.

  3. True
  4. False
  5. False
  6. True

Explanation:

A hypothesis is a supposition draw from data to carry an investigation or an argumentation.

1. The onion cells I looked at have a nucleus. False, even though the statement is true, is not a hypothesis because is not a supposition, it is rather an observation.

2. All onion cells have a nucleus. True, it is s a <u>valid hypothesis</u> because after the observation of 10 cells you draw a conclusion or supposition and affirm that all onion cells have a nucleus.

3. All cells have a nucleus. True, it is a<u> valid hypothesis</u> it contains a supposition derived from data observation

4. Some cells have a nucleus. False, the hypothesis is not valid because all of the observed cells contained nucleus not only some of them.

5. Only onion cells have a nucleus. False, after the observation of the different type of cells you see that they all had nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus. True, after the observation of different cells you can infer that if you look at your skin cells, they will have a nucleus.

4. A white albino rabbit lacks fur color. It carries the alleles rr. What is its
Marta_Voda [28]

Answer:

The phenotype of the rabbit is the absence of fur colour and the genotype is the alleles rr.

Explanation:

The genotype can be described as the genes which are present in an organism. Genes are made up of alleles. As the rabbit in the question carries the alleles, rr, hence it is the genotype of the white albino rabbit.

The phenotype can be described as the physical appearance that results from the particular genes present in an organism. As the white albino rabbit carries the alleles,rr, due to which it doesn't have fur, hence no fur is the phenotype of it.
