<span>A normal, typical and functional cell undergoes cell cycle in normal fashion and eventually reaches apoptosis. Yet cancer cells fail to display just some of these characteristics.

<span>A. They do not exhibit contact inhibitors
B. They lack specialization
<span>C. They have abnormal chromosomes </span>
<span>D. They fail to undergo apoptosis
</span></span>The cycle cycle; mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells.
Answer:
Regulation of intake is governed by thirst receptors that pick up signals of dehydration and return the body to a rehydrated state.
Explanation:
The state of hydration in someone's body is given by the plasma osmolarity values (the ratio of solutes to water in blood plasma). After regular activities that involve the loss of water, such as urination and sweating, happen, the blood begins to concentrate and the osmoreceptors located in the hypothalamus are triggered to generate a response that leads to water intake.
The repeating stages a cell experiences, including cell division, compose the cell cycle.
Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.
Interphase can be subdivided into:
• G1 phase characterized by the growth of the cell
• S where DNA replication occur
• G2 phase final preparation for mitosis.
Mitotic or M phase consists of:
• Prophase-condensation of chromosomes and mitotic spindle formation
• Metaphase-alignment of the chromosomes
• Anaphase- Sister chromatids are pulled apart by the mitotic spindle
• Telophase-each pole of the cell contain full set of chromosomes.
Two new cells are formed after cytokinesis.
Answer:
Right handed,right handed,positive,left handed, negative,negative
Explanation:
In a circular bacterial chromosome the structure of DNA is a right handed double helix.
if DNA is twisted in the right handed direction,it becomes overwound. overwinding results in positive supercoiling.
If the DNA is twisted in the left handed direction it becomes underwound. Underwinding result negative supercoiling.
one effect of negative supercoiling in bacterial chromosome is to promote separation of the two strands of DNA in the double helix.
