A very thin slice is removed from a peanut and treated with Sudan III, another indicator that turns red in the presence of a lipid. Then the same slice is treated with Biurets reagent. When the peanut is examined under a microscope, little patches of red and blue-violet can be seen. What conclusions can be drawn from this examination? Why would you expect this result?

Answers

Answer 1

Answer:

Little patches

Explanation:

blue- violet

Answer 2

Little patches and blue- violet.

What is Little patches?

Sudan III is a bis(azo) chemical that has a 4-[(2 methylphenyl)diazenyl]phenyldiazenyl group replaced at position 1 of the 2-naphthol ring. a fat-soluble dye that can stain some protein-bound lipids in paraffin sections and is mostly used to show triglycerides in frozen sections.

It functions as a histology dye, a fluorochrome, and a carcinogen. It belongs to the class of azobenzenes, is a bis(azo) chemical, and is a naphthol. It is similar to a 2-naphthol in terms of function.

"It certainly does not mean, as many writers have assumed, that the lipid in question belongs to the carbohydrate-containing glycolipid (cerebroside) group.

Therefore, Little patches and blue- violet.

Due to newly formed land.

Explanation:

Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation.

how do infrared waves, uv waves,and microwaves affect us

Answers

Answer:

Here is your answer

Explanation:

Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.

UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.

Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn.  But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.

A myelin sheath
B. axon terminals
C. cell body
D. axon

Answers

Answer:

Myelin sheath

Explanation:

Increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

What is Impulse?

The Impulse may be characterized as an electrical signal that can be transmitted along a nerve fiber in response to an external or internal stimulus.

The Myelin sheath increases the rate of nerve impulses. This is because it insulates the part of axons and reduces the chances of any disturbance in between due to the assemblage of voltage-gated sodium channels.

Therefore, increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

11. In which of the following examples will water move into the cells of the large intestine from the outside environment by the process of osmosis?​

Answers

Osmosis occurs in the large intestine to transfer water from the feces into the neighboring cells.

What is the process of osmosis?​

Water is transported across cell membranes through diffusion and osmosis. The body reabsorbs absorbable solutes and electrolytes from meals (namely salt, potassium, and chloride ions).

The total solute concentrations and the permeabilities of the solutes in relation to water define the effective osmolality of a biological fluid, the large intestine to transfer water from the feces into the neighboring cells.

Water molecules move by osmosis across the cell membrane from a lower solute concentration to a higher solute concentration.

Therefore, osmosis, a kind of diffusion, is how water enters and exits the cell's large intestine to transfer water from the feces.
