Answer:
a.They evade the normal controls that trigger programmed cell death.
Explanation:
Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.
Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.
Answer:
Phagocytosis in the inflammatory response
Explanation:
In the given question, the person is injured and is bleeding. This injury initiates the inflammatory response, a type of immune response to the injured site.
This inflammatory response recruits the defensive cells flowing in the blood called white blood cells to the injured site.
The white blood cells interact with these foreign bodies and may help eliminate foreign material.
One of the mechanism by this response is the phagocytosis which occurs when the monocyte WBC interact with the pathogen and engulf and degrade it.
Thus, Phagocytosis in the inflammatory response is correct.
It is because Prokaryotic cells has a unicellular structure compared to Eukaryotic cells which has a Multicellular structure.
Answer:
Protozoa are single-celled eukaryotes
Explanation:
Eukaroytes are organisms whose cells have nuclei
