Answer:
DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
Reproduction of new cells because if you were seriously burned the cell tissue would be dead and new cells need to grow to take the place of old cells
Answer:
More Carbon dioxide is removed from the blood and exhaled in the breath
Explanation:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.
The forms of pollution that each energy source cause include air, land, water, and even space and noise pollution.
The economy influences energy source choices by the cost efficiency consideration of choosing an energy source. There must be enough money to run the energy production and maintain the energy source.
Location influences energy source choices in such a way that different locations offer different availability of different resources.<span />
Explanation:
In a general way cells communication to each other through chemical signal which can be regarded as their language. Hormones, compounds and neurotransmitters behave like words that are spoken because they tell the cell about its environment and they also pass messages to the cells and the cell acts on the signal received. Each cells has receptors through which they detect different actions to be taken or signals that needs to be responded to, so they are always underground biological conversations.
