Answer:
The correct option is <u><em>A. they evolved from land mammals.</em></u>
Explanation:
The process of evolution explains how closely one organism is to another based on their common ancestors. Scientists believe that those organisms which show many similarities in their structures or functions might have evolved from a common ancestor in the past.
As in the above-mentioned question, scientists have observed that cetaceans lack gills and breath air, this is a property of land mammals. The cetaceans have fin bones which are similar to the limb bones. As limb bones are present in land mammals, hence they cetaceans and land mammals might have common ancestors in the past.

This organic compound is convert into the chemical energy or energy currency primarily, ATP during the process of glycolysis, the first stage or cycle of cellular respiration.
Thus, the correct answer is : ATP, glycolysis.
Answer:
Three types of population distribution:
Clumped.
Random.
Uniform.
Explanation:
1. Clumped:
This is the most common pattern of population dispersion.
organisms are clustered together in a group.
This may reflect the patchy distribution of resources in the environment.
2. Random:
This is a typical distribution where individuals do not interact strongly.
The organism has unpredictable distribution.
3. Uniform:
This is the typical environment where individuals compete with each other for scarce resources like water in the desert.
organisms are evenly spaced over the area they occupied.
