The fruit fly Drosophila melanogaster has an allele that confers resistance to DDT and similar insecticides, Laboratory strains
kherson [118]

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.

Which statement best describes how a catalyst can speed up a chemical reaction? A) The catalyst makes lower energy pathways avai
melamori03 [73]

Answer:

A) The catalyst makes lower energy pathways available.

Explanation:

A catalyst is a substance which speeds up a chemical reaction without itself being used in the reaction. Activation energy is the thresh hold energy which is required to initiate a chemical reaction. In the absence of catalyst, the activation energy is high therefore reactions are slower. But, presence of catalyst lowers the activation energy required to initiate the reaction as a result of which the reaction gets an alternate energy pathway to proceed which is responsible for speeding up the reaction.
