Answer:
The preferable option will be - 1.
1. The fish using ventral fins as "feet" will be present in increasing numbers.
Explanation:
After many years, the fish who are using ventral fins as "feet" will be present in increasing numbers because -
We know that
- These pools are temporary pools made up of rainwater. These pools do not last for longer times.
- Some fish have developed their ability to use their ventral fin as feet and can travel from one temporary pool to others.
- So, after many years, more and more fish will develop that ability to survive.
- As we all know about "the survival of the fittest" theory so some of them won't be able to make it.
- To develop their ventral fin as their real feet will take thousands of years and some genetic modification. So, that won't happen in many years.
Answer:

Explanation:
Chromosomes

Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.
