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.
Answer:
Population loss of small animals, forced migration of some populations and loss of habitat
Explanation:
The human sperm and eggs contain 23 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is called meiosis. It is used to produce cells for repair and asexual reproduction. Gametes do contain different genetic information to each other and to the parent cell.
Answer:
<em>The correct options are A) They move to another environment.</em>
<em>B) They risk dying out.</em>
Explanation:
According to natural selection, only those organisms are able to live and survive in an environment which can adapt to the changes in an environment. Such organisms reproduce and pass on their characteristics to their offsprings.
Organisms which are not able to adapt to changes in an environment either migrate to other places or die as they are not able to survive by the changes being made.
