Answer:

<h2>Gram staining is a technique used to differentiate between Gram-positive and Gram-negative bacteria.</h2>

Explanation:

Gram stain color the bacteria either red or violet depending on whether they are Gram positive or Gram negative. Gram positive  bacteria have thick cell wall containing peptidoglycan compared to Gram negative bacteria which have thin cell wall. Due to this Gram positive bacteria stains purple by crystal violet. So, slide containing <em>S. pyogenes</em> with purple violet indicates that it is a Gram positive bacteria.

Imagine a species with three loci thought to be on the same chromosome. The recombination rate between locus A and locus B is 35
Vesnalui [34]

Answer:

<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%. </h2>

Explanation:

As given,

Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.

Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.

Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%

A-----C ----------B

A---C= 2%

A----B= 35%

B---C= 33%

So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.

If the locus C is as,   A---35---B--33----C ;   A-----B------C

A-----B= 35%

B------C= 33%

A-----C= 33+35= 68%

As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.

How are the hydrogen bonds in water responsible for many of the molecules unique characteristics?
DiKsa [7]

Hydrogen bonds exhibit the stronger intermolecular force, and water is a polar molecule, so the hydrogen bonding create strong forces which take more energy to break (causing the surface tension of water), and due to the polarity water molecules “stick” to one another which causes the edges to rise up in a tube, forming a meniscus
