Why doesnt plants and bacteria expand when it reaches water

Biology
1 answer:
kap26 [50]3 years ago
5 0

When the plants and bacteria reach water, they get into a hypotonic solution means, the concentration of solutes is greater inside the cell than outside of it. When the plant and bacteria are placed in water, they take up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell become turgid. Turgidity means the cells are swollen and hard. The increase in pressure makes the cell rigid. This is why they do not expand and burst.

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%.

Triangle ABC is an equilateral triangle with side lengths labeled a, b, and c. Triangle A B C is an equilateral triangle. The le
kirill115 [55]

Answer:

One-half b c sine (60 degrees)

One-half a squared sine (60 degrees)

StartFraction a b sine (60 degrees) Over 2 EndFraction

Explanation:

The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.

From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.

∴ the three options that defines the expressions that represent the are of triangle ABC are:

One-half b c sine (60 degrees)  

i.e \frac{1}{2}bcsin60^{0}

One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.

i.e \frac{1}{2}a^{2}sin60^{0}

StartFraction a b sine (60 degrees) Over 2 EndFraction

i.e \frac{absin60^{0}}{2}
