Answer:
Answer is in the explanation.
Explanation:
Let's make a system of equations.
5x+10y=550
x+y=80
Now let's use elimination
-5x-5y=-400
5x+10y=550
__________
5y=150
y=30
Then subsitute 30 in for y to find x. This will leave you with x=50. You will have 50 $5 bills and 30 $10 bills. You can check by subsituting x for 50 and y for 30 in both equations to show why it is correct. Eliminating makes it easier to solve the system of equations.

Cross-pollination, or when pollen from one plant fertilizes another plant of the same produces outcrossing or outbreeding.
Explanation:
Cross pollination is the transfer of pollen from a plant's stamen to a different plant's stigma of the same species. They produces stronger plants. For example only pollen from a daisy can pollinate another daisy.
They have male and female reproductive units on separate plant. If they are on the same plant he pollen will not fertilize the female reproductive unit on the plant.
This process needs four steps pollination, germination, penetration of the ovule and fertilization. The Zygote divides to form an embryo after fertilization.
Genetic variation<span> can be caused by mutation (which can create entirely new alleles in a </span>population<span>), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).</span>
