this question is incomplete but I have added The Answer options to your question
a) He does not have a hypothesis.
b) He only has one group. He has not established a comparison
c) He has not measured an outcome.
d) The groups were not equal to begin with.
Answer:
b) He only has one group. He has not established a comparison
Explanation:
A randomized controlled experiment can be defined as an experiment that has two groups which it randomly assigns participants to.
These two groups are:
1.) the experimental group and
2.) The controlled group on whom the study is being performed.
Now Alberti does not have any of these groups we have listed. He performed the testing on the same people before they consumed alcohol and after they consumed alcohol. Therefore this study was not comparative in nature.
Answer:
The correct answer is A. Low energy availability
Explanation:
For an endurance athlete energy availability is very much important. An endurance athlete should eat at least 2000 calories even if he wants to lose weight.
So if an endurance athlete does not consume appropriate calories then during the performance his energy availability will be low which will affect his performance. Endurance athletes require more energy reserves in the body because they have to perform physical activity for a long time.
Therefore if an endurance athlete consumes too few calories then it will lead to a low availability of energy in his body.
Answer:
This indicates that the expression of genes depends partly on environment.
Explanation:
The case shown in the question is showing a situation where there was a genetic interaction with the environment, resulting that gene expression depends in part on the environment.
Gene and environmental interactions are revealed by penetrance and expressiveness. Penetrance is the percentage of individuals with a given gene that have a phenotype linked to this gene, such as children and parents who have the same height. In cases of penetrance, a genotype may not express the expected phenotype due to gene influences and environmental effects, as happened to the couples' children shown in the question.
