Answer:

The correct answer will be option-is secreted by the epithelial cells of both layers of the serous pericardium

Explanation:

Serous fluid is a fluid which resembles the serum of the blood in its color which is pale yellow to transparent.

The serous fluid is present in the cavities of the body organs like in heart, the fluid is present in the pericardial cavity.

The serous fluid lubricates the wall of the heart and is produced by the serous pericardial membranes. The secreted fluid gets collected between the pericardial cavity which helps slide the smooth movement of the serous layer against each other.

Thus, secreted by the epithelial cells of both layers of the serous pericardium is the correct answer.

I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?

These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".

1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU

2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L

3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B

An older adult female patient has presented with a new onset of shortness of breath, and the patient's nurse practitioner has or
Marizza181 [45]
Shortness of breath or difficulty in breathing is also called dyspnea and can be acute or chronic. It has various causes, but mainly can be caused by a problem in the heart or the lungs. Since your heart and lungs are both involved in the transportation of the oxygen to the tissues and the removal of carbon dioxide, any problems occurring to these systems can affect breathing.
B-type Natriuretic Peptide (BNP) reflect the systolic and diastolic activity of the heart and its blood levels can show any heart failure. A BNP test and can help the nurse decide whether the cause of the dyspnea is a heart failure or some respiratory problem.

In chickens, comb shape is determined by two independent genes (R and P). A walnut comb is produced when at least one dominant a
Aleksandr [31]

Answer:

Option B, Rr pp × rr Pp

Explanation:

Given

Walnut Comb is produces when  one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*

Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp

Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second  - rr P*

Single comb - two recessive alleles are present at the first and the second locus  - rrpp

Parent are rose combed and pea combed

For being rose genotype must be R* pp

and for being pea combed genotype must be rr P*

Rr pp x rr Pp

will  produce

Walnut comb  with genotype Rr Pp

Single comb  with genotype rrpp

and pea comb  with genotype rrPp

Hence, option B is correct
