A good topic idea that could be used can be about ecosystems. Such as how geographic area, plants, animals, weather and landscape make up the types of organisms in that specific ecosystem.
Answer:
No
Explanation:
Matter can not be created or destroyed it can only change form. For example two Oxygen atoms can react with one hydrogen atom to form water but the oxygen and hydrogen is not destroyed,
The DNA of the samples is isolated, and then the mapping is carried out, which is done by equipment called "DNA Sequencers". With this, it is possible to compare the genomes and conclude to whom the hair belongs.
<h3>DNA in the hair?</h3>
In the case of hair, researchers can rely on these two types of DNA (nuclear and mitochondrial). However, according to the Easy-DNA Laboratory, a hair that is cut, unfortunately, does not contain any valid DNA nucleus. However, when the hair still contains the hair bulb (hair root) it is possible to extract the nuclear DNA, because in that region we have thousands of hair forming cells (keratinocytes).
With this information, we can conclude that the DNA can be analyzed and compared, arriving at who committed the bank robbery.

The answer is 99.
Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.
