A and B are both correct answers, however with the statement of human cloning it does not lead to increased food production through biotechnology, so the only answer would be A
Carry information from the DNA to the ribosome for protein synthesis
<span>An example of an epithelial tissue where gases are exchanged is alveolar epithelium, which can be found in the lungs. This tissue is simple epithelial tissue. This is to be expected because the cell layer needs to be thin enough for the gasses like carbon dioxide and oxygen to diffuse or pass through. Stratified epithelial tissue contains several cell layers that would impair the exchange of gasses.</span>
That would be false because rocks are sediments.
Carbon 14 has a half life of 5,730 years. Scientists measure how much carbon 14 the rock has. For objects older than 50,000 years, scientists will test the age of the things surrounding it.
