What would decrease the amount of oxygen discharged by hemoglobin to peripheral tissues?
Marina CMI [18]

The following factors will decrease the amount of oxygen discharged by hemoglobin to peripheral tissues.

A) decreased temperature

B) increased pH

C) decreased amounts of DPG

D) increased tissue PO2

How oxygen is being transported?

About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.

What is the microscopic anatomical make-up of visceral muscles?
fiasKO [112]

Answer:

At the microscopic level of a visceral muscle cell are actin and myosin filaments. They slide past each other in an antiparallel manner to shorten the distances between their ends.  In a smooth muscle cell, the ends of chains of these functional units are attached to the cell membrane. They are several in a cell arranged in an elaborate framework. They contract together and deferentially to enable the muscle to contract as needed.

-why is respiration important for a cell?
Grace [21]
Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.

Tid-bit of info:
Cellular Respiration Formula:
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula: 
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆

The diagram below represents a flower, the reproductive structure of some plants. Most
Evgen [1.6K]

Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

<u>The structure represented by the letter A in the diagram is the stigma.</u>

The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
