Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol

Answers

In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.

Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.

Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.

In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

How can offspring be created that have a specific phenotype and genotype?

Answers

Explanation:

The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express. But when it comes to  apperences, a phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

Two women gave birth to girls in the same hospital at the same time. The nurses think they may have accidentally switched the babies' name tags and given the babies to the wrong parents. One baby, Jane, is type O blood. The other baby, Mary, it type A blood. The father in the first set of parents, the Reds, is blood type A and the mother is blood type B.The father in the second set of parents, the Greens, is blood type AB and the mother is blood type O.Which baby belongs to the Reds?

Answers

Answer:

Jane belongs to the greens

Mary belongs to the Reds

Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).

What is the ABO blood system?

The blood system is an allele system that determines the presence of antigens in the red blood cells.

In the ABO blood system, the A and B alleles are codominant, whereas the O allele is recessive and masked by A and B.

Mary is type A blood, whereas Jane is type O blood which can be due to the following allele combinations:

Reds

        A    O

B    AB  OB

O   OA  OO

Greens

        A        B

O    AO    OB

O    AO    OB

In conclusion, Mary belongs to Greens, whereas Jane belongs to Reds (it is due to the allele in the parents).

Describe the structures within cells that govern heredity, and describe where they are located. Make sure to have 5 sentences which have to be all on topic use great grammar along with great vocabulary usage.


!!PLEASE ANSWER CORRECTLY!!

Answers

Within cells, the long strands of DNA form condensed structures called chromosomes. Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes. cell nucleus
DNA is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). DNA contains the code for building and maintaining an organism.

Answer:

The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.

Explanation:

DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.
