Cancer cells are rogue clones. List and describe three mutations that allow these cells to escape the normal restrictions placed
Amanda [17]
<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.

In simple staining with a basic dye, do the gram-positive and gram-negative bacteria differ in retaining color?
Dmitriy789 [7]

Answer:

The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.

Explanation:

Stainings is a reagent or dye used to stain microscope specimens so as to make some structures visible.

Peptidogycan is a derivative polymer of glycan and peptides found in bacterial cell walls and varies in compositional concentration from species to species.

Cell wall- A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls). The cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and protecting the cell from damage.

There different types of staining techniques and classification based on the aim of the experiment and here is a few;

The etymology is from Gram + positive, is named after Dan ish bacteriologist Hans Christian Gram, who invented the Gram staining technique.

Used in bacteriology , bacteria that stains dark blue or violet after Gram staining, due to large quantities of peptidoglycan in the cell wall are gram positive.

And gram-negative bacteria is one that is not stained violet by Gram's method.

A spore is thick resistant particle produced by a bacterium or protist to survive in harsh or unfavorable conditions.

Spore staining (malachite green) however can be used to differentiate sporulating bacteria species.

The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.

A stickleback fish will attack a fish model as long as the model has red coloring. What animal behavior idea is manifested by th
GalinKa [24]

Answer:

Sign stimulus

Explanation:

Sign stimulus is a stimulus that will always produce the same behavioral response of an organism. In this case, red coloring is a sign stimulus for the fish attack which is its behavioral response.

This type of innate behavior is called  Fixed Action Pattern (FAP) because it is always the same (there is usually no variants in the behavioral response actions). If the model is colored differently, there is no behavioral response (attack).
