Answer:
"Examine the list of all known species of birds and determine if any species cannot fly" would be the most reasonable answer.
Answer:
The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.
Explanation:
deoxyribose + phosphate group + thymine
Answer;
C) the amount of time that the two species have been evolving apart
Explanation;
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
- The molecular clock hypothesis states that DNA and protein sequences evolve at a rate that is relatively constant over time and among different organisms. A direct consequence of this constancy is that the genetic difference between any two species is proportional to the time since these species last shared a common ancestor.
Concerns over a global dependence on fossil fuels include environmental, economic, and social consequences.
the answer is True
Answer:
Well plants are used for the animals that cheetahs eat if the animals like zebras didn't have the plants they would not survive.
