Question

  1. by which process are two daughter nuclei formed that are identical to each other and to the original nucleus?

a) meiosis
\t\t\t\t\t\t\t\t\t\t\tc) fertilization
b) synapsis
\t\t\t\t\t\t\t\t\t\t\td) mitosis

  1. during both mitosis & meiosis, double - stranded chromosomes are attached to the spindle fibers at the

a) centrioles
\t\t\t\t\t\t\t\t\t\t\tc) centrosomes
b) centromeres
\t\t\t\t\t\t\t\t\t\t\td) chromatids

  1. the process of meiosis is most closely associated with:

a) sexual reproduction
\t\t\t\t\t\t\t\t\t\t\tc) vegetative propagation
b) budding
\t\t\t\t\t\t\t\t\t\t\td) binary fission

  1. the pairing of homologous chromosomes during meiotic cell division is known as

a) synthesis
\t\t\t\t\t\t\t\t\t\t\tc) linkage
b) synapsis
\t\t\t\t\t\t\t\t\t\t\td) fertilization

  1. as a result of disjunction during meiotic cell division:

a) duplicate chromosome are produced
\t\t\t\t\t\t\t\t\t\t\tc) tetrads are formed
b) homologous chromosomes are separated
\t\t\t\t\t\t\t\t\t\t\td) crossing over occurs

  1. chromosomes do not normally occur in pairs in:

a) body cells
\t\t\t\t\t\t\t\t\t\t\tc) gametes
b) fertilized eggs
\t\t\t\t\t\t\t\t\t\t\td) zygotes

  1. the diploid number of chromosomes is restored by:

a) fertilization
\t\t\t\t\t\t\t\t\t\t\tc) eating
b) meiosis
\t\t\t\t\t\t\t\t\t\t\td) reduction division

  1. in the ovary of a frog, each primary egg cell that undergoes meiosis will probably

a) one active gamete
\t\t\t\t\t\t\t\t\t\t\tc) one gamete and one zygote
b) three active gametes
\t\t\t\t\t\t\t\t\t\t\td) four active gametes

  1. human eggs and sperm are similar in that both:

a) develop in specialized organs called gonads
b) have adaptations for locomotion
c) have the same relative amount of cytoplasm
d) are produced in approximately the same numbers

Explanation:

Response
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.

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.

Brief Explanations

Meiosis is involved in sexual reproduction (produces gametes). Budding, vegetative propagation, and binary fission are asexual reproduction methods.

Answer:

d. mitosis
