Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
Leftover radiation from the big bang is your answer hope i helped
Answer:
D and B
Explanation:
We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate. Therefore the student would need to provide warmth because its winter and water because that would satisfy the need for moisture. Hope this helps!

RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.
