Which is a density-independent factor for a flock of canada geese on a large lake?
question 7 options:

dwindling food supply

infectious virus

intestinal worms

unusually cold winter

unusually cold winter

Explanation:

Density independent factors are basically non-living things or factors that can badly influence the size of a population of living organisms. Here we are talking about the case of a  flock of Canada geese on a large lake. Things that can limit their population size irrespective of members of population's physical ability or fitness is unusually cold water, because it will equally affect all members of the population and pose serious threat for their survival.

Some other examples of Density independent factors are: pollution, Earthquake , floods, temperature etc.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

the answer is cell division : )
