Sharron did an experiment where she investigated how container size affected the growth rate of maple trees what is the independent variable
<span>Copying information in DNA is efficient because although the information must be copied individually, every single DNA strand still carries the necessary information that can be used in order to copy over during the replication phase.</span>
The second one is correct. Mitosis makes only two offspring, but Meiosis makes four that can be genetically different<span />
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
