Where are hydrogen bonds located in the nucleotides?
Answer:
A chemical bond between the phosphate group of one nucleotide and the sugar of a neighboring nucleotide holds the backbone together. Chemical bonds (hydrogen bonds) between the bases that are across from one another hold the two strands of the double helix together.

how do indicators help to observe things that are too small to see
Indicators are substances which possess measurable and observable characteristic which can be used to depict a the acidic or alkaline nature of a substance.
Indicators may be natural, those which exists naturally in nature such as litmus or turmeric.
Indicators such as Phenopthalein or Methyl orange are artifical indicators as they are obtained through laboratory preparation.
Blue litmus paper turns red when dipped into an acid while Red litmus turns blue when in contacts with a base.
Hence, indicators helps to know when a change in pH value of solution occurs.

Indicators change color in the presence of certain substances, which can be used to identify and quantify those substances.
An indicator is a chemical compound that changes color in the presence of another substance. This property of indicators can be used to observe things that are too small to see, such as individual cells or bacteria.
For example, the indicator litmus paper is red in acidic solutions and blue in basic solutions. This means that by dipping a piece of litmus paper into a solution, you can determine whether the solution is acidic or basic.
Another example of an indicator is the dye methylene blue. Methylene blue is colorless in acidic solutions, but it turns blue in basic solutions. This means that by adding a drop of methylene blue to a solution, you can determine whether the solution is acidic or basic.
Indicators can also be used to quantify the concentration of a substance in a solution. For example, the indicator phenolphthalein is colorless in acidic solutions, but it turns pink in basic solutions. The deeper the pink color, the more basic the solution is. This means that by measuring the intensity of the pink color, you can determine the concentration of the base in the solution.
Indicators are a valuable tool for observing things that are too small to see. They can be used to identify and quantify different substances in solutions.
Here are some additional details about how indicators work:
Indicators work by changing their structure in the presence of certain substances. This change in structure causes the indicator to change color.The color change of an indicator is reversible. This means that the indicator will return to its original color when the substance that caused the color change is removed.The color change of an indicator is specific to the substance that caused it. This means that a particular indicator will only change color in the presence of one specific substance.Indicators are a versatile tool that can be used in a variety of applications. They are used in laboratories to identify and quantify different substances in solutions. They are also used in everyday products, such as litmus paper and pH test strips.
