Because the mutation which does not have any effect on protein code I.e. even after the mutation if the gene still codes the same protein is called silent mutation
Answer:
Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.
Explanation:
Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.
- Performing the experiment on yeast would give good results for singular-celled organisms, like <em>protozoa</em>.
- Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like <em>spiders</em>.
- Performing the experiment on zebrafish would give good results for all fish in general.
Numerous barriers can prevent sperm from reaching and fertilizing the egg, this can be that the Sperm may be defected, or lack the required number of mitochondria needed to help move the sperm. Also, if sperm had already fertilized the egg, there is a change that takes place to the membrane surrounding the egg preventing further sperm from fertilizing.
