Biology

Question 1

What does ADN stand for

Answer 1

Acidedesocyribonucleique

Question 2

What form is ADN in and what are the structure of it

Answer 2

Double helice and sugar and phospahts

Question 3

What are the 4 bases of ADN, what goes with what, and where can you find ADN

Answer 3

Adenine, Thymine, Guanine, Cytosine
Adenine et Thymine
Cytosine et Guanine
The noyau

Question 4

What do the genes of ADN make

Answer 4

protein

Question 5

Name the 4 phases of mitose

Answer 5

Prophase, metaphase, anaphase, telophase

Question 6

What happens in prophase

Answer 6

They chromosones replicate themselves, the chromosones scramble, and the noyau dissapers

Question 7

What is reproduction asexuee

Answer 7

It is when you and only you make a copy of yourself. It uses mitose and makes an exact copy of itself, so there is no genetic variation.

Question 8

What happens in anaphase

Answer 8

The chromosones separate in opposite poles.

Question 9

Name the 5 types of reproduction asexuee

Answer 9

Funny babies say frig math
Fragmentation/regerneration, bourgeonnement, spores, fision binaire, meristemes

Question 10

What happens in metaphase

Answer 10

The chromosones doubles (they’re in the form of an x) form a line.

Question 11

What happens in telophase

Answer 11

The new noyaus start to form, and cytoscinese starts to happen.

Question 12

Name the stages of meisose

Answer 12

Prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, telophase 2.

Question 13

What happens in prophase 1 of meiose?

Answer 13

The chromosones do “enjambement” and find their homolouge

Question 14

What is the difference between mitose et meiose?

Answer 14

Mitose is used to make an exact copy of a cell, while meiose is used for genetic variety. Mitose is used for reproduction asexuee, but meisose is used for reproduction sexuee. Mitose creates 2 new cells somatiques, but meisose creates 4 new celles gametes. Finally, mitose uses diploides while meiose uses haploides.

Question 15

What is the diffence between male and female gametes?

Answer 15

Female gametes there is just 2 big eggs, while male gametes make 4 little sperms.

Question 16

What is reproduction sexuee?

Answer 16

It is how humans are made. For it, you need a male and a female, it uses meioses. The avantages of it is it creates genetic variety, but the negatives are, it is slow, takes a lot of energy, and you need a partner
