Accepted Answer

### Question 1
# Brief Explanations:
Mitosis produces two daughter nuclei identical to the original and each other. Meiosis produces non - identical daughter cells, synapsis is pairing in meiosis, and fertilization is fusion of gametes.
# Answer:
d. mitosis

### Question 2
# Brief Explanations:
During mitosis and meiosis, double - stranded chromosomes attach to spindle fibers at the centromeres. Centrioles are part of the centrosome, centrosomes organize spindle fibers, and chromatids are parts of a chromosome.
# Answer:
b. centromeres

### Question 3
# Brief Explanations:
Meiosis is involved in sexual reproduction (produces gametes). Budding, vegetative propagation, and binary fission are asexual reproduction methods.
# Answer:
a. sexual reproduction

### Question 4
# Brief Explanations:
Synapsis is the pairing of homologous chromosomes during meiosis. Synthesis is DNA replication, linkage is related to gene inheritance, and fertilization is gamete fusion.
# Answer:
b. synapsis

### Question 5
# Brief Explanations:
Disjunction in meiosis is the separation of homologous chromosomes. Duplication occurs in interphase, tetrads form during synapsis, and crossing over is exchange of genetic material.
# Answer:
b. homologous chromosomes are separated

### Question 6
# Brief Explanations:
Gametes (sperm/egg) are haploid and have unpaired chromosomes. Body cells, fertilized eggs (zygotes), are diploid with paired chromosomes.
# Answer:
c. gametes

### Question 7
# Brief Explanations:
Fertilization (fusion of gametes) restores the diploid chromosome number. Meiosis reduces chromosome number, eating is for nutrition, and reduction division is meiosis.
# Answer:
a. fertilization

### Question 8
# Brief Explanations:
In frog ovary, a primary egg cell undergoing meiosis produces one active gamete (egg) and polar bodies. Sperm production produces four active gametes, and zygote is formed after fertilization.
# Answer:
a. one active gamete

### Question 9
# Brief Explanations:
Human eggs (in ovaries) and sperm (in testes) develop in gonads. Sperm have locomotion adaptations (eggs don't), eggs have more cytoplasm, and sperm are produced in larger numbers than eggs.
# Answer:
a. develop in specialized organs called gonads
