How are cancer cells able to get nutrients away from your healthy cells?
chubhunter [2.5K]
<span>well this is an interesting question and i would say it may depend on what type of cancer cells you are growing and what type of "normal" cells your growing. One possibility is that cell fusion events may occur between your cancer cells and normal cells, thus creating a few options 1 - making the normal cell cancerous, 2 - making the cancer cell that fused with the normal cell not cancerous anymore. 3 - either way the fused cell will have a different genotype and hence be a different cell.</span>

When a baby is born, the zygote has become about _____ billion cells.
valentinak56 [21]

Answer:

<em>When a baby is born, the zygote has become about </em><em><u>26 </u></em><em>billion cells</em>

Explanation:

Cell: Cell is defined as the structural and functional unit of living thing. I.e The cell is the simplest and the basic unit of life. All living things are made of cell.

Zygote: A zygote is a single cell formed from the union of a male cell called sperm and a female cell called egg.

What is prophase, meta phase and anaphase labled under?
DedPeter [7]

Answer:

Technically Mitosis and Meiosis

Explanation:

Mitosis is the spliting of <em>Body Cells.</em> Mitosis goes through 4 phases that are easy to remember as PMAT. Mitosis starts with Interphase then moves to Prophase, Metaphase, Anaphase, and Telephase. These steps also occur in Meiosis. However Meiosis goes through these step twice. If you need further explaination of mitosis and meiosis I recomend the amoeba sisters.

Hope this helps!!

Select the five major mechanisms of antimicrobial resistance. Check All That Apply
Rudik [331]

Answer:

All the given statements are correct except b.

Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.

It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.

There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:

  1. Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
  2. Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
  3. Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of  para-aminobenzoic acid (PABA).
  4. Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
  5. Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
