C AND D
The frogs have a unique way to care for their young. The males scoop up the eggs in their mouths where they are kept in the vocal sac until the tadpoles hatch. Then they are "coughed up."
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Natural Selection is the process by which the most adapted, or fittest, species survive and the least adapted, or unfit, species do not survive. An example of Natural Selection is if there are two species of birds that eat the same thing, but one of the species has a beak that makes it harder to eat the food, naturally the species that has the beak fit to eat that food will survive. The species that is not fit to eat that food will either adapt or will be unable to survive. Evolution is a species adapting to the enviornment over a period of time. There is microevolution and macroevolution.
Active transport, which occurs at the expense of energy.
