A. Twelve cells with 16 chromosomes each
Answer:
Semi-conservative
Explanation:
Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).
Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.
Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.
Guess what? they show both! (See the image for more information)
The cyanobacteria from places like volcanic pools so important for the production of oxygen in our atmosphere because oxygen slowly reacts with bacteria and r<span>elease Oxygen. Thank you for posting your question here at brainly. I hope the answer will help you. </span>
Random distribution is the probable distribution pattern of opossums.
Explanation:
The opossums are the member of low density population. They are sparsely distributed because of the low number. There are troubles for them to find a mate.
Their habitat makes them solitary as they have flexible dietary habits. they are terrestrial animals living in burrows and are nocturnal.
They have random distribution pattern. The opossums are distributed in the population as random. The mates in opossums do not have choices of mates and the environment conditions in which they live are stagnant.(having no social life). Random interaction is seen in <em>species which do not have any social bonding</em> between the species of the animals or plants.
