Answer:
2) is chemically specific
Explanation:
Enzymes are organic catalysts which speed up or control chemical reactions in cells. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reaction. Enzyme salivary amylase found in the mouth only hydrolyses starch into maltose.
<u>Unusually cold winter</u> is a density-independent factor for a flock of Canada geese on a large lake.
Density independent factors mean that those factors/variables affect the density of the population. However, the density of the population, on the other hand, does NOT affect the variable.
Explanation:
The other factors are density-dependent except unusually cold winter. The cold is not affected by the population density of the Canadian geese. However, an increase in cold causes the population density to decrease because some individuals in the population will be unable to cope with the cold. Only individuals with traits favorable in the bitter cold survive.

Answer:
No because the tectonic plate theory says that they move but if they didn’t move then it proves it wrong.
The answer is B. A dependent variable is one that varies according to the modulated independent variable. In this case, the independent variable is A -‘The amount of Drug x given to the mice’ since it is the one that is being controlled in the experiment.
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
