Answer:
Two heterozygous parents have a <u>50%</u> chance of contributing one of their alleles to each offspring.
Explanation:
Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.
The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.
On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.
Answer:
Moving against the concentration gradient, or in simpler terms, moving from a low-concentration area to a high-concentration area.
Explanation:
This action uses energy, as according to entropy, the substance will move from a higher concentration to a lower concentration, and cells have to put extra energy to pump the molecules / substance up the concentration gradient.
It is mostly used to trigger chemical responses in cells, like in neuron synapses.

1. Any cone-bearing trees would release their seeds. These trees make the fires advantageous to their species by having the seeds "explode" when heat touches the cones.
2. The ashes from the burned trees would help nourish the released seeds.
3. New wildlife will begin as the baby trees develop and grow
