Which is used to calculate standard deviation, X stands for ______ value.

Biology
1 answer:
andreev551 [17]3 years ago
3 0

Answer:

X is the quantity value

Explanation:

To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.

1. An enzyme is considered a(n) ____ because it speeds up a chemical reaction without being used up.2. In a catalyzed reaction,
Zepler [3.9K]

Answer:

(1)Catalyst, (2) substrate, (3) active site, (4)activation energy, (5)induced fit, (6)cofactor, (7)denature

Explanation:

An example of an enzyme is carbonic anhydrase. It catalyzes the reversible reaction between water and carbon dioxide, in the body, to form carbonic acid. This reaction would normally be very slow but is sped up in the body. This allows the body to regulate the pH of the blood and also helps gets rid of carbon dioxide from the tissues.

emmasim [6.3K]
The cell wall is what gives plant cells their shape. The cell wall, not to be confused with the cell membrane, is a rigid structure made up of long cellulose fibers, branching hemicellulose fibers, and pectin. The fluid pressure inside the cell also contributes somewhat to their shape.

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.
