Answer:
DNA replication follows semi conservative mode of replication
Explanation:
The results of Meselson and Stahl's experiments can be explained by semi conservative mode of DNA replication. According to it, the two DNA strands separate and both are used for synthesis of new DNA strands such that the new DNA molecule has one parental and one new strand.
In the experiment, originally the medium was 15N so all the DNA molecules had 15N. Later the medium was changed to 14N. In first round of replication in new medium, the two 15N strands in a DNA molecule separated and formed new strands using 14N. So all the DNA molecules had one 15N and one 14N strand.
In the second round of replication, the 15N-14N hybrid DNA molecule separated again. Now, 15N gave rise to 14N strand and 14N strand also gave rise to 14N strand such that half of the DNA molecules were 15N-14N hybrids and half were 14N-14N. Hence, researchers concluded that DNA replicated according to semi conservative mode of replication.

Answer:
A - G1 phase
B - G2 phase
C - S phase
D - Mitosis
E - Interphase
Explanation:
Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase
G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.
During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.
<span>Ecosystem is where a group of living organisms are associated with its environment factors such as minerals or any non-living elements. These organisms and it's environment are in linked with each other through the cycles of energy and flows of chemical to each of them.</span>
the flowers are generally so beautiful and attractive to attract birds and insects for helping the plant to reproduce. when the bird or insect lands on some other flower, some of the pollen spreads and pollination occurs.
