Answer:
The most effective experimental approach to assess the effects of elephant impact on vegetation is to assess plant responses under differences in elephant density. It is important that other factors, such as soils or habitat structure are held constant so that the only factor which varies is elephant density.

d. carbon atoms in ocean water
Explanation:
The carbon atoms in ocean water is one of the ways through which carbon is sequestered in nature.
Sequestration of carbon implies the storage of carbon either naturally or artificially for a very long time.
Carbon sequestration cuts off carbon from the normal biogeochemical cycle and stores it in natural reservoirs for a very long duration.
- In nature, carbon is sequestered a whole lot through biological and chemical activities.
- Phytoplanktons are food producers. When consumed by higher organisms, their organic materials which contains carbon can become sequestered when the consumer dies and falls to the bottom of the ocean.
- Organisms that used carbonate to manufacture their shells in the ocean also sequesters carbon.

Prokaryotes are single celled organism that lacks a membrane bound nucleus, mitochondria, or any other membrane bound organelle. Examples of prokaryotes include all single-celled organisms, most of which are bacteria. The principle ecological role of prokaryotes is to break down organic matter.
Answer:
2. Alec Jeffreys
Explanation:
'DNA fingerprinting' or DNA typing (profiling) as it is now known, was first described in 1985 by an English geneticist named Alec Jeffreys. Dr. Jeffreys found that certain regions of DNA contained DNA sequences that were repeated over and over again next to each other.
