Answer:

Infrared

Explanation:

To calculate the wavelength if the electromagnetic radiation, we must use the following formula:

c = f × λ

where c is the speed of the wave (in this case it's the speed of light, which is 3 × $10^{8}$ m/s) , f is the frequency and λ is the wavelength.

Using this formula, all we have to do is plug in our values and rearrange for the answer:

c = f × λ

3 × $10^{8}$ = 5.00 x $10^{12}$ Hz × λ

λ = 3 × $10^{8}$ /5.00 x $10^{12}$

λ = 6.00 × $10^{-5}$ m = 6.00 × $10^{4}$ nm

Now that we know the wavelength we can figure out which kind of electromagnetic radiation this is.

6.00 × $10^{4}$ nm falls in the range of infrared radiation. We know this either from memorizing the values of the wavelengths or looking up a reference.

A fish is removed from a contaminated lake. You determine that a particular toxin (X) is present in its cells at concentration X

netineya [11]

The level of toxins in the fish's cell is equivalent to the level of toxins in the water. Therefore, in order to reduce the toxins further, we should replace the now contaminated water with clean water. After the level of toxins in the fish's cell stops reducing, we replace the water with clean water once again.

Explain what a glycosolation reaction is

AVprozaik [17]

Answer:

The glycosylation reaction or glycoside formation is an organic reaction in which the hemiacetal group of cyclists ketoses or aldoses turns into acetals, named glycosides. Reaction in the attached picture.

Explanation:

Carbohydrates can be found in an open-chain form or a cyclic form. For the second one, the carbonyl group of the aldehyde could react with the alcohol group of the molecule to form the cycle. As shown in the attached picture, the alcohol group of this cyclic form could react with an alcohol (like methanol) in acidic conditions to form an acetal. These compounds are stable at neutral and acidic conditions, but they hydrolyze at basic conditions. This reaction produces both acetals anomers (α and β) because the attack of the nucleophile (alcohol) could be from both sides. However, the most stable anomer will predominate.
