Energy. A solute can only move against concentration gradients using active transport which requires energy
Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.
Answer:
they give the nutrients to the primary consumers.
Explanation:
producers are like-plants that are consumed by deer/bunnies etc. All those nutrients will decrease at the upper levels at the food chain so they have to have enough nutrients to keep the animals alive and healthy. When the lion eats the deer ( it was an example) some of the nutrients and minerals that the deer ate from the plant will be consumed by the lion while its being eaten.

Wheres the picture for this
We'll make the alleles: Cc.
C is a healthy parent, and c is the cystic fibrosis (recessive).
If you make a punnett square and the parents are both Cc (healthy), then you would get CC, Cc, Cc, and cc. That cc is a 25% chance that the offspring will have that, which means there is a 25% chance the child will have cystic fibrosis.
Two healthy parents can have a child with cystic fibrosis if both the parents have the dominant allele and recessive allele, if both the parents have heterozygous alleles.
