How do the respiratory and circulatory depend on each other for gas exchange?
Juli2301 [7.4K]

Answer:

Explanation:

Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will

carry oxygen which is transported around the body.

denis-greek [22]

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC  -->1/16  

RRCc,  RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

Which statement most accurately explains how allosteric regulation can change an enzyme's catalytic activity? View Available Hin
Digiron [165]

Answer:

In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.

Explanation:

Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
