Aman who carries an x-linked allele will pass it on to: 1) all of his daughters 2) half of his daughters 3) all of his sons 4) half of his sons 5) all of his children

1. All of his daughters.

Explanation:

A man has only one X chromosome, and it is paired to a Y chromosome, so during meiosis, his gametes (sperm cells) will either have an X or a Y chromosome. This chromosome defines the sex of the offspring in humans, so if his child gets an X chromosome, it will be a girl. If a Y, then it will be a boy. So no boys will get any alleles linked to the X chromosome, but all girls will.

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

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.

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.

contains the organelles; site of most cell activity

the place where ribosomes do their working activity.

builds the proteins.

prepares proteins for use or export.

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