The correct answer is:
D. It divides one diploid cell into four haploid cells.
Explanation:
Meiosis is a specific type of cell division that reduces the chromosome number by half, forming four haploid cells, each genetically different from the parent cell that yielded growth to them. Meiosis is a method where a single cell divides double to produce four cells comprising half the innovative amount of genetic information.
Answer:
The correct answer is B. DNA replication is semiconservative.
Explanation:
With this experiment, Messelson and Stahl determined that there was a pattern in replication that left one original strand and added a new one in each case. Therefore, after two rounds, there will be two copies with "original" information exclusively and two copies with mixed strands or hybrids.
Ecosystems need producers because they are the start of the food chain.
Producers are consumed by first consumers, the second consumers and so on.
