The correct answer is D
A) The simple sugars would have less energy than the complex sugars, because the molecules are smaller.
B) The simple sugars would have more available energy, because they are small molecules and are easy to break down.
C) The complex carbohydrates would produce the most energy, because they have a high C:H ration and relatively little oxygen.
D) All of the carbohydrates would produce about the same amount of energy, as they all have a large amount of oxygen atoms.
Answer:
C
Explanation:
Proteins are organic molecule in a enzyme, but amino acids are a type of protein. The answer is C.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels
Answer/ Explanation:
If an animal is more visible to predators, it is more likely to be caught and killed than an animal that is more hidden.
Therefore, in this case, light green frogs will be caught by predators more often. This reduces their likelihood of surviving to reproductive age and being able to pass their genes on to their offspring.
In contrast, frogs that are dark green will be more able to avoid predators, increasing their chance of being able to pass their genes on to offspring.
Therefore, if there are more green frogs reproducing and passing their information on to the next generation, then there will be an increased frequency of the alleles responsible for producing a dark green colour, whereas the alleles for the light green colour will reduce in frequency. This how the process of natural selection occurs.
