Answer:
The statement which is correct is
<em>The evolutionary fitness associated with the heritable trait of DDT resistance changed once DDT use became widespread.</em>
Explanation:
In the 1930's, the usage if insecticides was minimal. Hence, the genes for DDT resistance were absent or silent in the fruit flies at that time.
In the 1960's, the DDT resistant forms of fruit fly began occurring at this rate because they were better adapted to survive. According to Darwin, the species which are better able to adapt to the environment survive and are able to reproduce. Hence, with the passage of time the resistant forms of fruit fly will keep reproducing and increase in number.
Answer: In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time
Explanation:
usually this is the measuring device of amount of rain fall.
you can buy these, but most of the time meteorologists will have these to measure the amount of rain fall
Answer:
They would react the same as with the vinegar and hydrogen peroxide at room temperature.
Explanation:
In this experiment catalase acts as the catalyzing enzyme which decomposes hydrogen peroxide. All living things (be it frozen liver or a potato) consists of catalase. Such enzymes decompose one substance into another. Catalase enzyme helps in breaking down hydrogen peroxide into water and oxygen and also speed up the process of decomposition by providing and maintaining favorable situation. Therefore, irrespective of whether this catalase is found in the frozen liver or potato, they would react in the similar manner.
Hence, option A is correct
Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
