Answer:
Sympatric speciation
Explanation:
There may be more than one answer here, but concerning speciation, sympatric speciation can't occur because of the geographic isolation (must be living in the same environment for this to occur).

Answer:
- The geography of the continents (they fit each other, contain similar mountain ranges, etc)
- The distribution of fossils and rocks
- The locations of ancient climatic regions
Explanation:
The continental drift theory states that continents moved across geologic time, plowing through oceans and drifting to different parts of the planet. The continental drift theory is associated with Alfred Wegener, who the first in using this terminology in 1912. Some of the most important lines of evidence that support the continental drift theory are the movement of continents on tectonic plates, the presence of evolutionarily related plant and animal fossils in different continents, paleoclimate indicators (e.g., glacial striations), etc.
Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
Answer:
THYROID GLAND
Explanation:
Thyroid gland functions in metabolisms by activities of thyroid cells.This cells withdraws Iodine from metabolites and combine it with amino acid tyrosine for productions of Thyroid hormones:
ThyroxineT3,(20%)
TriiodothyronineT4(80%). This production is under the influence of Thyroid stimulating hormones,regulated by the pituitary gland,
T3 and T4 increase calorinogenesis, (liberation of heat from digestion to supply energy,and oxygen consumption of the heart.)
Deficiency of thyroid hormones are goiters, hypothyroidism, and hyperthyroidism
