Answer:
the fish experienced an evolutionary change because of genetic drift
Explanation:
<h2><u>Answer</u> :</h2>
The correct option is A. If a dominant allele is present, the recessive allele won’t be seen.
The dominant allele is the one which appear, and the recessive one isn't shown.
For example - If a person has 2 alleles of eye colour as B ( black ) and b ( brown ), in which black is dominant and the brown one is recessive, then the person will have black eye colour because only dominant allele shows its characteristics.

Answer:
The moon.
Explanation:
High tides and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon.
Answer:
it is complicated but you add 1+1 and get two
Answer:
The correct answer would be reproduction.
Single-celled organisms usually reproduce asexually with the help of cell division.
Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.
Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.
Unicellular organism usually divide by fission either binary or multiple.
In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.
In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.
