A lab is given a tissue sample to examine. In this tissue sample it appears that cells have abnormal chromosome counts and form cell masses. In addition, the cells are still dividing after more than 50 cell divisions. Which of the following might account for this cell behavior?
Mitosis
Meiosis
Cancer
Crossing Over

A cloned animal has a diploid chromosome number of 24. What is the diploid chromosomes number of the animal cell that was used to produce the cloned animal?
6
12
18
24

Which of the following would be an example of asexual reproduction?Required to answer.
A single celled eukaryotic cell (for example an amoeba) divides in half to form two amoebas
A beetle transfers pollen from one flower to another.
Earthworms exchange sperm packets
Corals release eggs and sperm into the ocean.

Prophase of Meiosis 1 is a unique phase in which synapsis occurs. In synapsis, homologous chromosomes come together as pairs. They form a tetrad consisting of four chromatids. Because they exist as tetrads
The chromosome number can increase
The chromosome number can decrease
Homologous chromosomes are identical
Homologous chromosomes can exchange genes

In meiosis, cell/s become cells at the end of its two phases
Two haploid; four diploid
Four haploid; two diploid
One diploid; four haploid
Four diploid, two haploid

Cancer is often characterized by tumors. Which would most likely trigger the formation of a tumor?Required to answer.
A parasite that both lived and reproduced within the human body
A mutation in a gene that codes for a protein regulating cell division
A change in the DNA sequence of a gene that codes for skin coloration
A bacterial infection that caused inflammation and swelling in body tissues

Cancer cells are body cells that do not function properly, leading to abnormal growth. Which process does not function normally in cancer cells?
Osmosis
Cell cycle
Photosynthesis
Cellular Respiration

The cell cycle is a repeating sequence of cellular growth and division during the life of an organism. Which of the following is NOT a true statement concerning cell division of body/somatic cells?
Cells divide in a process called meiosis
Cells divide in order to maintain homeostasis
Cells divide when the parent cell gets too big
d. Cells divide in order to repair themselves when damaged

Construction workers attach ropes and pulleys to wooden timbers on an old bridge. They use the rope and pulley system to move the timbers away from each other, in order to dismantle the bridge. Which stage of mitosis is similar to this way of dismantling a bridge?
Anaphase
Metaphase
Prophase
Telophase

As part of the cell cycle, a cell produces new daughter cells that are identical to the original cell. During which phase are the two daughter cells physically separated?Required to answer.
Cytokinesis
Synthesis Phase
First growth phase
Second growth phase

During meiosis, homologous chromosomes line up next to each other. If one arm of a chromatid crosses over the arm of another chromatid, what results?
The creation of an additional sex cell
The independent assortment of genetic material
A possible change in the offspring cell’s functionality
Additional variation in the DNA combination of each sex cell formed.
