Answer: No
Explanation: It is beneficial if the animals that are disadvantageous doesn't reproduce so it doesn't discredit natural selection. The traits in which variation is occured are more suitable for organism to live and reproduce in the environment are preserved and are passed from generation to generation.
However, natural selection effects limited number of progeny.
Examples of skeletons protecting the body are, the rib cage for the heart and lungs, and the pelvis for the nerves in the lower body. Your spinal chord has bone to protect to protect the sensitive nerves inside.
Answer:
Explanation:
Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.
Therefore, the only cell that expresses GAL4 is cell C-2.
The arrangement is:
1. Construct 1 should express GAL80
2. Construct 2 should express GAL80
3. Construct 3 should express GAL4
4. Construct 4 should not be used
