Answer:

Use a series dilution

Explanation:

The rationale behind the experiment is that the different substances absorb light at different wavelengths. To prepare an absorption spectrum for a purified solution of b-carotene dissolved in acetone, firstly, the \beta -carotene needs to be diluted enough to reach the light spec in the 20 tube. This will be done through a series of serial dilutions of a known concentration of the chlorophyll component. The bankmill will consist of acetone only and 1 blank will be needed. The range of the wavelength would be in the range of 400 - 700 nm. So, the intervals of 20 nm will suffice. Then, the OD for each wavelength will be used to determine the adsorption.

Scene: A savvy investor has a mix of stocks and bonds in their investment portfolio. Why would it be a good idea to mix stocks a
Komok [63]

Answer:

Explanation:

It wouldn't now, unless you are very wealthy. Interest rates are very low and you would have to go into the junk bond market to get any kind of decent return. But Junk Bonds are or can be very unstable and you get a high return for a very chancy situation.

I think I know what the question wants you to understand. You need something that will provide with income. You just don't want to deal with bonds. There are stocks around that pay dividends; they are very conservative and if they go down, that will be the least of your problems.

You can then devote your resources to capital gains or pure stocks: no interest payments, but the stock itself goes up. There is a whole different tax system for capital gains.

You should also get some gold or silver as insurance.

Since you have asked about stocks and bonds, I have not said anything about cryptos. That's an option, but you have to be very knowledgeable because those things can be an investment nightmare.
