Answer:
The relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.
Answer:
They release energy as they degrade polymers to monomers.
Explanation:
In a catabolic pathway, complex hydrocarbons are usually broken down to their monomeric units.
This breaking down leads to the release of energy.
- Anabolic pathway leads to the build up of energy. One of such process is photosynthesis.
- The catabolic pathway breaks down compounds to simpler units in order to release energy.
The second group is the:
Option D. control group
