Answer:
The main ingredient of cells is water. Water is needed to maintain homeostasis. Cells are also made up of macromolecules—nucleic acids, lipids, proteins, carbohydrates. These macromolecules help maintain a cell's structure, help cells communicate with each other, aid in energy storage, etc.
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies
:
- <em>Red eye (R) is dominant trait.
</em>
- <em>White eyes (r) is the recessive trait.
</em>
When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square
:
<em><u>Rr X Rr
</u></em>
<em>Alleles R r
</em>
<em>R RR Rr</em>
<em>r Rr rr</em>
In the offspring, the probabilities are:
- 50% heterozygous individuals Rr, with red eye phenotype.
- 25% pure dominant individuals RR, with red eyes
- 25% individuals with the recessive rr genotype, white eyes.
<u>This is the possibility of two red-eyed flies having white-eyed offspring</u>.
ocean has a large body of water (a major part of the hydrosphere) that is characteristic to or located in the region adjacent to either side of the equator while rain forests are luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall as it creates a major difference in ocean zones and rain forests.Oceans are areas of salty water that fill enormous basins on the Earth’s surface.Both are governed by cycles, ranging from seasonal to multi-year. Both contain an array of plants and animals that are dependent upon that ecosystem. And both produce vast quantities of a resource vital to life on earth: fresh water evaporated from the oceans, and fresh oxygen from the trees and greenery in the rain forest.The ocean floor is like a rain forest, because feces and dead animals rain from the sky. These two are both great examples of biodiversity

Explanation:
Osmosis is about the diffusion of water in and out of cells, so the answer is D.
Because if there's not a lot of a species it's likely to go extinct
