Explain how it is possible to have thousands of different protiens when there are only 20
solmaris [256]
This is possible because proteins are created from different combinations of amino-acids. While we only have 20 different kinds of aminoacids, these 20 kinds can create thousands of combinations that we can observe in our bodies and bodies of other mammals as well as other organisms.

Somebody explain this in short?
Olenka [21]

significant digits are certain digits that give detail in a number

ex. in the number 400 it is the 4 because it tells you how many hundreds are in the number, in the number 49.92 it would be all of them because they all help understand the number

Do you get it?

A plant biologist is asked to develop strawberry plants with larger, sweeter berries. Through selective breeding, the biologist
frutty [35]

Answer: Clonal progagation

Explanation:

Clonal propagation involves the production of identical individual without the fusion of germ cells. It can be multiplication through stem and other plants part such as leaves.

Strawberry as a fruits can be multiplied using the stems thus preventing the germ cells from genetic recombination that could lead to the formation of entirely new plants. It does not involve the union of male and female germ cells.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions
Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
