Rotation is the motion that causes us to see phases
Answer:
1000, 2000 and 3000.
Explanation:
The example given in the question is of a DNA with 4000 base pairs and it is being cut at 1000 pairs, 1500 pairs and 3000 pairs. So the lenghts of the segments that are cut from the original spiral are 1000, 500, 1500 and 1000 respectively. And the information that only the linear fragments are being produced is given to us in the question so the sizes of DNA expected would be 2000, 1000, 3000 and 2000 again respectively.
I hope this answer helps.
Out of the following given choices;
A. DNA accumulates mutations at a regular rate
B. known mutation rate for a gene
C. the number of differences in DNA sequences for a gene in two species
D. the same gene identified in two species
E. All answers are corrects
The answer is E. The molecular clock used rates of mutation to determine the prehistoric time when two species that share a common ancestor diverged. The benchmarks for determining the mutation rate are often fossil or archaeological dates.
<span>b.) A more biodiverse ecosystem has a higher chance of adapting to species changes.

Answer:
B. Dehydration
Explanation:
Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.
Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.
For example: RCO2H + R′OH ⇌ RCO2R′ + H2O
In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH
The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.
Hence, the correct option is B. Dehydration.
