Evolution of a species could occur as a result of changes in the
victus00 [196]

Options for the question have not been provided. They are as follows:

(1) DNA in muscle cells

(2) base sequences in liver cells

(3) genes in an egg cell

(4) number of chromosomes in a fetal bone cell

Answer:

(3) genes in an egg cell

Explanation:

Evolution is the change in characteristics of a species which it develops over the time. These changes can be a result of natural selection, genetic drift, founder effect etc. They are passed from one generation to another hence the alleles for them get fixed in the population.

For evolution to occur, change should take place in germ cells. Germ cells are the one which fuse to form the organisms of next generation. If there is a change in their genes, it would also appear in next generation, unlike changes in genes of somatic cells. Since egg cell is a germ cell it is the correct answer.

Answer: C. Preying

Explanation:

A non-native species is the species which is introduced to a new ecosystem. This species is introduced intentionally or accidentally to a new ecosystem by human beings or they may enter to the ecosystem by their own.

A non-native species can be invasive which means it can compete with the native species for resources like shelter, food and mates.

According to the given situation, the Gila trouts being the native species has been affected by the non-native Rainbow trout. This may be because of the fact that non-native species can be invasive for the native species. As the species is used as mate by the non-native species and they may become the prey of non-native species. This has resulted in the extinction of the species of Gila trouts.
