Answer:

through synaptic transmission as action potential , which transmits the action potential across to synapse( neuromuscular juction ) to reach the postsynaptic end plate. the end -plate terminated on the muscles to bring response.

What are the contents of the crop?

sineoko [7]

There are two types of agricultural crop residues. Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves, and seed pods. The residue can be ploughed directly into the ground, or burned first. Good management of field residues can increase efficiency of irrigation and control of erosion. Process residues are materials left after the crop is processed into a usable resource. These residues include husks, seeds, bagasse, molasses and roots. They can be used as animal fodder and soil amendment, fertilizers and in manufacturing.

At a PO₂ of 70 mm Hg and normal temperature and pH, hemoglobin is ________% saturated with oxygen. At a PO₂ of 70 mm Hg and norm

Arturiano [62]

Answer:

D) over 90

Explanation:

As we know, hemoglobin is the protein found in red blood cells that is in charge of oxygen transportation, and the relation between the percentage of oxygen that binds to hemoglobin and the partial pressure of oxygen in the blood can be represented through the oxygen - hemoglobin dissociation curve, as shown in the attached image.

As we can see in the image, the curve has a sigmoid shape, and this is due to the allosteric interactions between the subunits of the hemoglobin, which change their conformation with each oxygen molecule that binds in order to increase even more the oxgen affinity. This curve is constantly shifting to the right and to the left depending on the conditions of the blood, like temperature, pH, partial pressure of carbon dioxide and the concentration of diphosphoglycerate (DPG).

When the PO2 is around 70 mmHg, as we can see in the curve, the hemoglobin is saturated around 90% or more, reaching a plateu in the curve where the oxygen is not binding as fast anymore, because there are almost no more free binding sites left in the hemoglobin molecule.
