Answer:
A. a developing nation
Explanation:
Age pyramids are the age structure diagrams that represent the number and proportion of people at each age in a population. The base of the age pyramids represents the population in pre-reproductive age which is from 0 to 10 years. The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.
The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.
For the answer to the question above asking <span>In aerobic respiration, what is the direct source of energy that ATP synthase uses to synthesize ATP?</span><span>I think this is Proton Gradient. It is t</span><span>he product of the electron transport chain. A higher concentration of </span>protons <span>outside the inner membrane of the mitochondria than inside the membrane is the driving force behind ATP synthesis.</span>
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
Carbohydrates in size from smallest to largest is monosaccharide ( single sugar), disaccharide( two or three sugar), Polysaccharide( polymers of many sugar in large chain). Thus, polysaccharide have largest chain of itself.
<h3 /><h3>What are Carbohydrates?</h3>
Cn(H2O)n is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.
Initially the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula CH20.
In modern Era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy.
Therefore, carbohydrates in size from smallest to largest is monosaccharide ( single sugar), disaccharude( two or three sugar), Polysaccharide( polymers of many sugar in large chain). Thus, polysaccharide have largest chain of itself.

Answer:
Oxygen is required by all cells for cellular metabolism and circulating blood must be well oxygenated for maintenance of life. Carbon dioxide is a waste product of cells and must be eliminated or a serious change in pH can occur, known as acidosis.
