Identical twins are formed from one fertilized egg, but fraternal twins form from two different fertilized eggs. Apply your knowledge of mitosis and meiosis to explain the genetic differences between identical and fraternal twins.

Identical twins share the exact same DNA while fraternal twins do not.

Explanation:

Mitosis is the type of cell division that results in 2 individual cells that have the exact genetic material.

Meiosis is the division of reproductive cells, eggs and sperms, which results in new cells with half the amount of genetic material and that makes them unique.

Identical twins are twins developed from a single egg that has been fertilized with a single sperm, meaning they have the same DNA.

Fraternal twins are twins from two different eggs that have been fertilized by two different sperms and grow in the womb at the same time with no additional cell division. So they have different DNA's.

I hope this answer helps.

q: compare the parts of a cell and the cell as a whole to another common nonliving system (i.e., a car, a city,

a:

comparing this to the inside of a food building/company.

plasma membrane - building's walls

all cells are surrounded by a plasma membrane, which protects the cell from its environment, keeping toxic substances out of the cell. it regulates which molecules are allowed to enter and exit the cell.

nucleus - the big boss

regulates all cell activity such as cellular metabolism, and growth in addition to storing and maintaining the cell's dna for transcription and replication. determines what proteins to make.

cytoplasm - working areas

contains the organelles; site of most cell activity

endoplasmic reticulum - engineer's work area

the place where ribosomes do their working activity.

ribosomes - engineers

builds the proteins.

golgi apparatus - pickup truck drivers

prepares proteins for use or export.

lysosomes -   investigators

responsible for breaking down and absorbing materials taken in by the cell.

cytoskeleton - renovators

maintains cell shape.

mitochondria/chloroplasts - materials scientist

transforms one form of energy into another.

The answer is c : ) hope this answered your question!
