Evolution of a species could occur as a result of
changes in the
(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

The correct answer would be (3) genes in an egg cell.

Evolution is the process by which genetic makeup or composition of a population gradually changes over a number of generations.

It could take place due to the number of factors such as natural selection, a mutation in germ cells, genetic drift, inbreeding et cetera.

It leads to the change in the heritable characters of a population which may or may not provide survival adaptations to the population.

As we know, only germ cells take part in the production of gametes (egg or sperm) and responsible for passing genetic material from one generation to another.

Hence, change in genes in an egg cell can pass from one generation to the next and can cause evolution.

Other cells such as muscle cells, liver cells, bone cells, et cetera are called as somatic cells which do not take part in the formation of gametes and thus they do not transfer their genetic material from parents to the offspring.

Hence, any change in the sequence of somatic cells would not result in the evolution.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
