What specific type of bacteria reproduces through binary fission every hour. If there are three bacteria cells to begin with how many bacterial cells will there be in five hours?
32
Name a type of cell found in human blood that uses phagocytosis for capturing and destroying bacteria?
Blood cells use phagocytosis for capturing and destroying bacteria. More specifically, white blood cells. They fight off infection and bacteria.
What is the main requirement for a chemotherapeutic drug to treat cancer cells?
A chemotherapeutic drug used to treat cancer must be more toxic to cancer cells (at least, to the cancer cells of the specific type of cancer which it is intended to treat) than it is to the healthy cells of the body. Otherwise, you could only kill the cancer by also killing the patient.
What cell is cancer made of?
Cancer isn't really a specific cell it is just the inability for some cells to stop reproducing.
What are the similarities between specific and non specific immune responses?
Both involve white blood cells Both responses have means of killing invading cells like bacteria or parasites
How can gamma waves benefie people?
They are used to kill cancer cells , and also harmful bacteria in food and on surgical instruments.
What is your body fighting in disease?
An infection caused by a virus or a bacteria or in the case of cancer, cells of your own body that have gone rogue.
Four of the five cells listed - viruses cells - MHC markers - cancer cells - bacteria - dead cells - are targets of the immune system - Select the exception?
MHC markers- which are proteins that present or "show" antigens like bacteria to other immune cells. Instead of being targets, they are helper proteins of the immune system.
White blood cells that attact and destory bacteria are called?
Leukocytes that attack foreign molecules (including bacteria) include Eosinophils, basophils, neutrophils, and monocytes. These cells participate in "non-specific" immune responses, meaning they aim for any and all foreign materials, not just one specific one. If those non-specific cells don't succeed, the lymphocytes, which target specific microbial cells, will reinforce the others to kill the microbial invader. Specifically, here is what each does to aid in the destruction of bacteria: 1. Neutrophils - phagocytic (cell eaters). 2. Basophils - produce histamine (inflammation) and heparin (clotting). 3. Eosinophils - reduce inflammation (in allergic reactions). 4. Lymphocytes - immunities and specific defenses. 5. Monocytes - the biggest cell, becomes a phagocyte during infections (macrophage).
What cells primarily target cancer cells?
Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include: Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells. Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens. Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer. Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer. Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells. Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells. These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
2 cell types that have no hayflick limit?
- Bacteria, because their chromosomes doesn't have telomeres- Cancer cell, because the telomerasegene in DNA is expressed and makes the cancerous cells almost immortal- Stem cells (for the same reason)- Germline(for the same reason)
Can your own immune system kill a small amount of cancer?
No, it can't, not to my knowledge anyway. cancer is a mutation of healthy cells into cancerous cells. its not a virus or bacteria that is foreign to the body. it is a mutation of your body. I may be remembering my info wrong though
