Answer:
this study is clearly an observational work
Explanation:
experimental studies involve to establish direct associations between a traits and its phenotypic effects. For example, a classical experimental study would involve to map a nonsense mutation in the ACTN3 gene significantly correlated to the non-sprinting phenotype
Answer:
altitude sickness, hyperventilation and loss of appetite. Hypoxia is another problem humans may experience due to a decrease in pressure of oxygen.
Explanation:
The blood rushes to the wound and clots forming a scab
Answer:
(3) completing a data table of expected results
Explanation:
Observation and research of the available literature about the process under study are some of the tasks done before experimentation. The data table of expected results is not to be made before any research.
Research and discussion on the basic information about the enzyme under study, the search of any experiments done on the same enzyme earlier gives insight about the enzyme. This is followed by making a hypothesis and setting the experiment to test the hypothesis.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. If there is no variation, then all individuals have the same chance to survive and nothing will be particularly selected.
