Answer:
Explanation:
Organisms are well preserved in mud because mud has high water holding capacity. It retains water and does not allow oxygen flow which can destroy the remains of organisms. There are some microbes that preserved whose growth are enhanced in water related environment like mud.
But sand cannot retain or hold water. It drains it off and all oxygen bearing water to flow which enhance decay compared to mud. It can't preserve organisms because of the above reasons.
Answer:
B. very high genetic variation
Explanation:
Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.
This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.
Answer: Options A, B, D and E.
A. Process for initiating.
B. standard reporting format.
D. process for synthesizing the body of evidence.
E. process for finding and assessing individual studies.
Explanation:
Systematic review is a scientific process which combines findings from research using random sampling of works from different source of a particular subject and integrating them into a powerful and clinically useful report to guide practice. It is a form of paradigm that guides and aids further research in a particular field.
However, there are components to be considered in other to create a perfect resolution. Initiation of the process begins with gathering of research from different source.
Then, individual research work is also accessed to derive facts and putting up a standard report to explain the total discovery.
