Which statement describes the chromosome theory of inheritance?
Alleles for specific traits are carried on a particular chromosome.
The traits of offspring are unrelated to the traits of the parents.
Parents pass their genes on to offspring on chromosomes.
Offspring inherit two copies of each gene from each parent.
Which statement describes an offspring’s chromosomes?

Each parent gives a full copy of chromosomes to the offspring.
One chromosome in each pair comes from each parent.
The father gives all of his chromosomes to the offspring.

To answer the questions:
1. Which statement describes the chromosome theory of inheritance?
The correct statement is: Parents pass their genes on to offspring on chromosomes. This is known as the chromosome theory of inheritance, which states that genes are located on chromosomes and are passed from parents to offspring during reproduction.
2. Which statement describes an offspring's chromosomes?
The correct statement is: One chromosome in each pair comes from each parent. Offspring inherit a set of chromosomes, with one chromosome coming from each parent to form a pair of homologous chromosomes.
3. Which nitrogen base is found only in RNA and not DNA?
The correct answer is: Uracil. RNA contains four nitrogen bases: adenine (A), cytosine (C), guanine (G), and uracil (U). Uracil replaces thymine (T) found in DNA.
4. Chromosomes carry what from parent to offspring?
The correct answer is: Genes. Chromosomes contain genes, which are segments of DNA that code for specific traits and are passed from parents to their offspring during reproduction.
5. Where does protein synthesis take place?
The correct answer is: On the ribosomes in the cytoplasm of the cell. Protein synthesis occurs on ribosomes, which are located in the cytoplasm of the cell. The instructions for protein synthesis are encoded in the DNA and transcribed into RNA, which then moves out of the nucleus and onto the ribosomes where the actual synthesis of proteins occurs.
