SDSU Bio-101 Exam 2 Questions With All Correct
Answers A+ Solution Guide
The type of cell division associated with the growth of an organism is called - ANSWER>>mitosis
Sexual reproduction results in many benefits for a population, but not without some
inconvenience; for example, - ANSWER>>- each participant must locate an appropriate mate.
- the time and effort required for finding a mate may mean that short-term benefits for survival
are missed.
- sexual reproduction requires special cells to occur.
Mature nerve cells, which don't undergo cell division, usually do not exit ____________ of the
cell cycle. - ANSWER>>G0 phase
Sister chromatids detach from one another and become visibly separated in mitosis during -
ANSWER>>anaphase
Human somatic cells are - ANSWER>>diploid
In what ways does a somatic cell differ from a gamete? - ANSWER>>- Somatic cells are diploid
(2n), whereas gametes are haploid (n).
- Somatic cells are created by mitosis, whereas gametes are created by meiosis.
- Somatic cells can differentiate into many cell types, whereas only two types of gametes exist.

chromosome number by half during meiosis.
An unreplicated chromosome contains - ANSWER>>a single molecule of DNA combined with a
large number of proteins.
, After a single cell undergoes meiosis, how many new cells will be produced? - ANSWER>>4
Cancers are groups of cells that divide rapidly and uncontrollably. Thus cancer cells probably -
ANSWER>>have a relatively short interphase.
By the time a cell enters meiosis II, it has - ANSWER>>become haploid.
