1. eukaryotic genomes consist of:

a) circular dna

1. human body cells contain how many chromosomes?

a) 23
b) 46
c) 92
d) 8

1. somatic cells are described as:

a) haploid
b) diploid
c) polyploid
d) triploid

1. gametes contain:

a) two sets of chromosomes
b) no chromosomes
c) one set of chromosomes
d) 46 chromosomes

1. homologous chromosomes are:

a) identical
b) different lengths
c) matched pairs with the same genes
d) rna molecules

1. a gene is:

a) a bundle of proteins
b) a functional unit of chromosomes
c) a type of rna
d) only in prokaryotes

1. the cell cycle consists of:

a) mitosis only

Explanation:

• Question 8: Eukaryotic genomes have multiple linear chromosomes. Prokaryotes have circular DNA. RNA is not the main component of genomes in this context.
• Question 9: Human body (somatic) cells are diploid. The diploid number of chromosomes in humans is 46 (23 pairs).
• Question 10: Somatic cells are diploid (have two sets of chromosomes). Haploid cells have one set (like gametes), polyploid has more than two, and triploid is a specific case of polyploidy.
• Question 11: Gametes (sperm and egg) are haploid, so they contain one set of chromosomes.
• Question 12: Homologous chromosomes are matched pairs (one from each parent) with the same genes (but may have different alleles). They are not identical (unless in a clone - like situation for a specific gene due to mutation etc., but generally not). They are not RNA molecules.
• Question 13: A gene is a functional unit of chromosomes (a segment of DNA that codes for a product - usually a protein). It is not a bundle of proteins, not just RNA, and is present in both prokaryotes and eukaryotes.
• Question 14: The cell cycle consists of interphase (where the cell grows and replicates DNA) and mitosis (cell division). So it's not just mitosis.

Answer:

1. C. Several linear chromosomes
2. B. 46
3. B. Diploid
4. C. One set of chromosomes
5. C. Matched pairs with the same genes
6. B. A functional unit of chromosomes
7. (Since the options for 14 are incomplete in the user - provided text, but if we assume the full options, the cell cycle has interphase and mitosis. If we consider the given options, the cell cycle is more than just mitosis. But as per the given options, if there was an option with interphase and mitosis, that would be correct. Since it's not fully shown, but based on the partial options, we know it's not just mitosis. However, if we assume the intended answer from basic knowledge - the cell cycle has interphase and mitosis. But with the given options, if we consider the most correct among the shown (assuming the user might have cut off), but strictly based on the given options for 14: The cell cycle is more complex than just mitosis. But if we have to choose from the given (assuming no other options), but the proper answer is that the cell cycle has interphase and mitosis. But as per the given options in the problem (even if cut - off), we know A is incorrect as the cell cycle is not just mitosis. But without full options, we can't give a proper multiple - choice. But if we assume the intended knowledge - the cell cycle has interphase (G1, S, G2) and mitosis (M phase). But since the options are cut - off, we can't give a proper multiple - choice. However, if we consider the basic fact for 14: The cell cycle is not just mitosis. But if we have to pick from the given (assuming no other options), but this is a bit of an issue. But for the other questions:
8. C
9. B
10. B
11. C
12. C
13. B
