During photosynthesis plants need constant supply of sunlight but they produce glucose a constant supply for respiration.

Explanation:

Photosynthesis take place in 2 steps, First is light dependent and followed by the light independent phase.

The light independent reaction two important molecules are formed, they are ATP and NADH. This reaction phase takes place in the thylakoid membrane of the chloroplast in the presence of sunlight. Because of this continuous supply of sunlight is required for photosynthesis. This will be followed by Calvin-cycle or light independent reaction where glucose and Carbon dioxide are the end products.

In cellular respiration glucose is the substrate along with oxygen forms energy for various metabolic activities to take place inside the organism.

So, it is seen that product of photosynthesis is the reactant for cellular respiration.

Increased afterload physiologic change increases cardiac work but does not enhance cardiac output.

<h3>What about cardiovascular system?</h3>

Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
Blood vessels also transport waste such as carbon dioxide to be disposed.
Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
The heart, blood arteries, and blood make up the cardiovascular system.
Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.
The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.

Mastering biology Chapter 13 - Question 3 - Multiple Choice Homology is evidence of ________.

Fudgin [204]

Answer:

Homology is evidence Divergent Evolution

Explanation:

When we study DNA sequences from different species, we conclude that all the living organisms have been arise from a single common ancestor and due to homology between different species, it is also concluded that organisms now-a-days are a result of Divergent Evolution from a single common ancestor.

A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecul

hoa [83]

Answer:

Explanation:

I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
