What additional information would assist you in determining whether polar bears and grizzlies are different species, based on th
e biological species concept? I. whether the F1 is fertile
II. whether F1 offspring are viable
III. the amount of DNA sequence divergence between polar and grizzly bears
IV. the geographic distribution of polar and grizzly bears
a. II only
b. I only
c. III and IV only
d. I and III only
e. I and II only
According to the biological species concept, a species is the population of organism in which the individual are able to interbreed with each other and also able to produce viable and fertile offspring.
Therefore here to determine whether polar bears and grizzlies are different species we have to get information that whether the F1 generation of grizzlies and polar bears is viable and able to produce their own offspring that means are F1 generation fertile. So the correct answer is e. I and II only.
I want to say individuals more so than entire populations. That being said it's because the entire populations of living things are able to evolve and move forward through slow evolution.
If
CUAGCUCGAUAUCUC is a mRNA sequence then the codes are:
CUA - Leucine
GCU - Alanine
CGA - Arginine UAU - Tyrosine
CUC – Leucine
<span>This means that the protein synthesized
during the translation is going to have a sequence LeuAlaArgTyrLeu.</span>
Answer - C Snakes periodically shed their skin in order to regrow new skin. Birds migrating to the south and bears hibernating are also a result of normal periodic transitions. However, extinction of a type of shrimp is most likely a result of a drastic change in the environment.
