Explanation:
Answer:
Option C - The sympatric salamander populations evolved their present body sizes after they became sympatric.
Explanation:
First, note the definitions of each terms.
1) Sympatric occurs when organisms especially of same species occurring in the same, or in overlapping territory, do not interbreed.
2) Allopatric occurs when organisms are NOT living in the same territory and thus unable to crossbreed.
On 1st QUESTION
The argument would be strengthened by the failure of P. cinereus and P. hoffmani to crossbreed making traits for body size to become distinct (dissimilar) in each specie.
On 2nd QUESTION
Definitely, salamanders species occurring in the territory, do not interbreed after they became sympatric, thus, making characters among same species to be increasingly different over generations.
Answer:
mL of oxygen in 
ml of blood
Explanation:
It is proven that a healthy human being has in general 
grams of hemoglobin in milliliters of blood.
It is given that -
Amount of oxygen found in 
grams of hemoglobin is equal to 
milliliters of oxygen.
Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.
mL
Answer: It leads to 4 daughter cells.
I hope this helps.
Since cells have specific functions and capabilities, unicellular organisms have less capabilities and more or less have one job. Functions are reduced with unicellular. Humans, for example who are multicellular, have functions for cell regeneration, clotting, nerves, etc and therefore have a longer list of functions that unicellular organisms like bacteria
