Explanation:
This process is known as nucleosynthesis. But the universe was still too dense and hot for electrons to join these nuclei and form stable atoms. That's a busy first second. Next we'll find out what happened over the next 13 billion years.
DNA fingerprinting is far more conclusive because it is solid proof. It has evidence that a certain person was at a certain place at a particular time frame. Although most criminals do get asked to use the polygraph test, testing guilt I guess, measures only their heart rate. Which in a normal view many regular people would be nervous. There has been countless reports where murders can pass a polygraph test, but then be convicted of a crime due to proof of evidence from fingerprints. Humans are emotional beings, some can crack easily while some won't (through interrogation). So that's why it's key investigations use science to back up their crimes rather that try to measure someone's guilt.
I hope this answered your question!
Answer:
an amino group and an R group
"Each of the 20 amino acids has a central carbon atom with four covalent bonds. These bonds link the carbon atom to an amino group ( NH2 ), a carboxyl group ( COOH ), a hydrogen atom, and an R group. The R group can be a carbon side chain, a hydrogen atom, or a functional group. " -------- from my textbook.
Explanation:
The molecular formula of an organic compound indicates the number of atoms of each element that make up a molecule of the substance and the proportion between them.
<h3>What is the molecular formula?</h3>
The molecular formula indicates the actual number of atoms of each type of chemical element that appears in the molecule. For example, the molecular formula for water is H2O, which means that in every water molecule there are two hydrogen atoms bonded to one oxygen atom.
With this information, we can conclude that the number of atoms of each element that make up a molecule of the substance and the proportion between them is called molecular formula
