Answer:
C. Changes that convert light energy into chemical energy stored in carbohydrates
Explanation:
Just had this question on a bio assignment.
Answer:
interphase before mitosis
Explanation:
The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
So it is the very last stage!
The scientist should notice that the cancer cells have a <u>higher</u> rate of cell division and have a <u>lower</u> response to inhibiting factors. Cell groups that are cancerous should have a <u>lower</u> percent of cells in interphase than noncancerous cells.
Explanation:
The general characteristics of cancerous cells are defined by the ‘hallmarks of cancer’ like ‘enable replicative immortality, activate invasion and metastasis, resist cell death, evade growth suppressors’ etc. All these facts prove that they grow and divide at a higher rate and undergo uncontrollable mitotic cell division leading to proliferative invasion.
The cancerous cells also show low or no response to inhibiting factors like growth suppressors like p53, cyclins and other anti-tumor drugs.
The number of cancer cells in interphase is lower than noncancerous cells because interphase is a phase of cell growth, development and differentiation. Cancer cells undergo uncontrollable mitosis and more time is spent after the interphase to facilitate rapid cell division rather than growth or development.
