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)
Answer:
Competition - interaction occurs when two or more than two species depend on the same resources, sharing the same habitat and niche.
Explanation:
The Protons and Electrons are equal to the atomic number (41). And the mass number (162) <span>is equal to the sum of the number of </span>protons<span> and </span>neutrons<span> in the nucleus. So to find the number of Neutrons, just subtract 41 (number of protons) from 162 (mass). That means element X has 121 Neutrons.</span>
