,Question 7: Genetic inheritance is being studied in a certain
species of plant in which orange flower color (O) is dominant to
white (o) and round leaf shape (S) is dominant to oval (s). A
true-breeding orange-flowered, round-leaved male plant (Plant A) is
mated with a true-breeding white-flowered, oval-leaved female plant
(Plant B) to produce dihybrid offspring plant (Plant C). Assuming
normal Mendelian genetics and independent inheritance of these
two traits, which gametes might be produced by Plant C?
A. OoSs
B. OS
C. oS
D. Both OS and oS
E. Both OoSs and OS
Answer:
Both OS and oS

divides?
A. The cytoplasm divides into four parts
B. Gene mutation

, C. Cancer
D. DNA replication
Answer:
DNA replication


Question 10: The division of the cytoplasm following mitosis to
form two new cells is called?
A. Mitosis
B. Cytokinesis
C. Cancer
D. Tumor supression
Answer:
Cytokinesis


Question 11: Which of the following is the correct order of events in
mitosis?
A. - Sister chromatids line up at the metaphase plate. The kinetochore
becomes attached to the mitotic spindle. The nucleus reforms and the
cell divides. Cohesin proteins break down and the sister chromatids
separate.
B. - The kinetochore becomes attached to the mitotic spindle.
Cohesin proteins break down and the sister chromatids separate.
Sister chromatids line up at the metaphase plate. The nucleus
reforms and the cell divides.
C. - The kinetochore becomes attached to the cohesin proteins. Sister
chromatids line up at the metaphase plate. The kinetochore breaks
down and the sister chromatids separate. The nucleus reforms and
the cell divides.
D. - The kinetochore becomes attached to the mitotic spindle. Sister
chromatids line up at the metaphase plate. Cohesin proteins break
