<h2>Scientist Observing changes </h2>
If the population of the species is significantly decreasing then the species could become extinct. The decline in population is due to some factors like less immigration, aging, and decreasing fertility rates. But the most is due to less immigration which causes to decrease population. The extinction of population can be prevented by some serious actions which should be taken government.
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.
Mosses were one of the first plants to even evolve.
A divergent boundary is a place where two tectonic plates are pushed apart by the formation of new crust rising up from the mantle. At a divergent boundary you would expect to find:
Rift Valley
Mid-Ocean Ridge
Deap Sea Trench
New Oceanic Crust
According to the research, birds are uniquely classified from other organisms because they all have feathers.
<h3>What are birds?</h3>
It is an oviparous and vertebrate animal whose body is protected by plumage and which has a pair of wings generally suitable for flight.
Feathers are characteristics of the bird class thanks to these they can camouflage, regulate body temperature and identify and differentiate themselves from other groups of animals since they may have wings, beaks and legs, but none have feathers.
Therefore, we can conclude that according to the context, birds are uniquely classified from other organisms because they all have feathers.
