MEIOSIS. Questions
A) Describe what occurs between step 1 and 2.
B) What is the end product of meiosis I?
C) What is the end product of meiosis II?
D)Look at the cells in step 4. Are they all the same?
E) What will the cells in step 4 mature to become?
Answer:
A. DNA replication
B. Two haploid daughter cells
C. Four haploid daughter cells
D. No, they are not the same
E. Gametes
Explanation:
A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.
B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.
C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.
D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.
E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.

Explanation:
Akira creates a reaction without a catalyst, then repeats the reaction with a catalyst.
Answer:
Akira turns in a written lab report to his science teacher. ... Akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowered the activation energy needed to start the reaction.
