I have a few science questions that I need help with. Can anyone help?

Question

1) Explain the process of passing on chromosomes and the duplication of DNA.

2) What are the stages of Mitosis in the correct order?
(The stages are metaphase, telophase, prophase, and anaphase)

3) Hemoglobin picks up __________.
A) carbon dioxide
B) wastes
C) nutrients
D) oxygen

4) What percentage does one chromosome make up in a human?
Hint: Humans have 46 chromosomes.

A) 5.2% B) 3.8% C) 1% D) 2.2%

5) If an organism's sex cell contains 8 chromosomes, how many chromosomes are in the body cells of that organism?

A) 8 B) 16 C) 32 D) 64


Please answer as many as you can or tell me how to find the answer, like a website or something.

6) How does the body work like a system? Include details about cells, tissues, and organs and how they are related.

Answer 1

1. Look up mitosis on wikipedia. The explanation is too long to include here.
2. See above.
3. Oxygen.
4. 1/46 = 2.2%.
5. The number they are looking for is 16.

Answer 2

1)
2)
3) D
4) D (1/46)
5)B (8 x 2 = 16) cuz the sex cell only has half the chromosome

Answer 3

2. Prophase, anaphase, metaphase, telophase ( I thinkk)

5. B 16

Answer 4

The best way to tell you to find the answers is to use your textbook. I'm assuming, of course, that this is part of a homework assignment for a biology class. So, get your book, READ the chapters, and then you will be able to answer the questions.
