Answer:
The number of trophic level in food chain is limited because at each trophic level a large amount of energy is being utilized for the maintenance of organism and lost as heat.

Answer:
FTFT, F, FFT (in order left to right)
Explanation:
The twist allele is FT, the forked allele is F. We are told there are pure lines, so this means they are homozygous. That means the parents are FF x FTFT.
The F1 generation is both twisted and forked (as can be seen from the image), suggesting the alleles are codominant (both are expressed).
In the F2, there are three different types of flowers, 2 matching the parental and 1 matching the F1 twisted, forked, and both.
The order from left to right is twisted, forked both. We know twisted is the genotype FTFT, and forked is the genotype FF. The both phenotype would have a copy of each allele, so would be FFT
Answer:
extra calcium
Explanation:
it binds to the vesicles in the terminal axon and induces exocytosis. If there is more calcium, more neurotransmitter will be released
