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.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
