For everyone who loves science,here are some minor difficult question that I bet you can't answer.

Just so you know this is my 7th GRADE STUDY GUIDE! Yes I need help. Yes my teacher needs help,but I still love her and she's still my favorite teacher.
1. State the role of DNA in heredity.
2. Describe the contribution of Watson and Crick to the study of the DNA molecule.
3. Label a DNA subunit (nucleotide). Include deoxyribose sugar,phosphate group,and nitrogen base.
4. List the four nitrogen bases found in the DNA molecule.
5. List four nitrogen bases found in a RNA molecule.
6. Compare the base pairing rules in DNA molecule with the base pairing rules involving a RNA molecule.
7. Compare and contrast a DNA and RNA molecule.
8. LOL,Define Gene(So easy)
9. Identify DNA as the material that makes up chromosomes.
10. State the functions of chromosomes/DNA correctly using terms "trait" and "proteins.
11. Correctly relate the terms DNA,gene,and chromosomes.
12. Give examples of non-reproductive (body)cells.
13. Give examples of reproductive cells(gametes or eggs or sperm).
14. Compare the number of chromosomes in a non-reproductive/body cell and a reproductive cell/gamete.
15. Compare and contrast the terms diploid and haploid.
16. Relate the terms diploid and haploid to non-reproductive and reproductive cells.
17. Identify the types of cells that undergo mitosis(non-reproductive), the outcome of mitosis(including the number of cells and chromosome number[diploid or haploid] of cells), and the phases of mitosis.
18. State the purpose of meiosis using the terms "chromosomes" and "reproductive cell or gamete".
19. Give a simple overview of the steps of meiosis.
20. Compare and give examples of the following pairs of terms: genotype and phenotype; homozygous and heterozygous; dominant and recessive.
21. State the Law of Independent Assortment and give an example of its application.

1.i know it has like the blueprints for things??
2.they made the first dna model and presented it to the world
3.i dont really get the question but some subunits are sugar, nucleotides, amino acids
4, 5(their the same question) didnt learn
6.didnt learn
7.one of them makes ribosomes
8.didnt learn (not easy for me)
9.dont get the question
and the rest i didnt learn and im in 7th grade too well prob learn it farther in the book
and just so you dont think im a total idiot i aced the tests on that ch
in ch.1 we barely scratched the surface of DNA
and then the beginning of ch.2 (were on the last sec.) we did subunits and a tiny bit of DNA and RNA
1 thing i did learn about DNA and RNA is what they stand for and how to spell it
DNA - deoxyribonucleic acid RNA- ribonucleic acid
prob cuz we have a quiz after each sec and then the ch. test
we also were doing some labs with the microscopes which takes a couple of days
but i like it cuz its like a review after each sec. so i know the whole ch. better
