Answer:
Double Helix
Explanation:
It is called the double helix for the signature shape that a DNA strand takes.
By using ratios. You get a punnet square and then get the ratio or even the percentage.
Answer:
B. Every point on the line is an equivalent ratio.
C. As the line goes up, the speed increases.
D. Simone can pick any ratio on the line and she will be swimming at a rate of 2 mph.
Explanation:
If the line on the graph has equivalent ratio, it shows that the Simone swim at the speed of 2 mph. If the line on the graph goes up , it means the speed of swimming increases while when the line on the graph goes down, the swimming speed decreases so maintaining the speed of 2 mph, the line have to go horizontally in straight line. If Simone can pick any ratio on the line present on the graph so she has to swimming at a rate of 2 mph.
<h3><u>Answer;</u></h3>
Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.
<h3><u>Explanation;</u></h3>
- Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
- Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.
