Answer:
If one animal's population increases, the population of animals that eat that animal might also increase. Increases in population aren't always beneficial.
Explanation:
Sometimes a population will grow too large for the environment to support. Other changes in limiting factors can cause a population to decrease.

Answer:
Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
Answer:
D. Type II alveolar cells
Explanation:
Three layers together make the diffusion membrane or respiratory membrane, which make the total thickness of less than a millimeter i.e. about 0.2 micrometer. The three layers are as follows:
1. The squamous epithelium of alveoli. There are two types of alveolar cells called type I and type II. Type I makes the exchange surface of alveolar membrane and type II cells are responsible for secreting the lung surfactant that reduces the surface tension.
2. Endothelial lining of blood capillaries. These is rich network of blood capillaries near the wall of alveoli.
3. In between the squamous epithelium and the endothelium of blood capillaries fused basement membrane is present.
Answer:
The correct option is B. Fermentation would occur at a similar rate to that of glucose.
Explanation:
Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.
