Explanation:
DNA synthesis occurs during the S phase, between the G1 and G2 phases of interphase. DNA replication is therefore complete before the mitotic phase begins.
The amount of dissolved oxygen decreases with increase in temperature.
However, in chart 1 it was observed that the amount of dissolved oxygen increases with increase in temperature.
<h3>What is the relationship between dissolved oxygen and temperature?</h3>
Dissolved oxygen is the amount of oxygen dissolved in water at a given temperature. Dissolved oxygen is important to aquatic animals for respiration.
The relationship between dissolved oxygen and temperature is that dissolved oxygen increases with decrease in temperature and vice versa.
Based on chart dissolved oxygen initially had a linear relationship with temperature. This, however is contrary to the expected results.

Explanation:
HIV virus is an RNA virus
There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.
There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.
Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.
These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
