The environmental scientists use technology to track polar bears by radio collars to track their movements.
<h3> How can the bears be tracked? </h3>
There was an observation made by the Scientists as regards the bears in their natural habitats which made them to make of use radio collars to track their movements.
It should be noted that this collar is been design to sends signals via satellite and this is been utilized in ploting the bear's path.
However, Only female polar bears can be tracked with radio collars, hence The environmental scientists use technology to track polar bears by radio collars to track their movements.

The last one is false, the plates are almost always moving
I
assume the question asks for the number of phenotypes present.
The
phenotype is the set of visible characteristics of an individual resulting
from the interaction of its genotype. In this case, the number of phenotype is
the total number of combinations of the characteristic purple or white and
wrinkled or smooth:
<span>purple
and smooth
white and smooth
purple and wrinkled
white and wrinkled</span>
<span>So
basically there are 4 phenotypes. (ANSWER)</span>
Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.
