The student should make sure that the instrument she will be using to measure the pH of the water is valid.

Validity is concerned with an object's goal is able to measure the intended object.
<span> With this conclusion validity, our data gathered and presented are considered a reasonable one. It is the most important types of validity. As what is said, by having conclusion validity, your data will be undoubtedly least considered since it is labelled as statistical and well-studied.

Why is insertion/deletion of three bases less deleterious than insertion/deletion of one or two bases.
Ede4ka [16]

Answer:

Explanation:

Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.

If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.

However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.

Alex Ar [27]

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.

<h3>What is carbon dioxide?</h3>

Carbon dioxide is one of the gases that cycle around in the universe. It is an integral part of the carbon cycle. The carbon cycle is a model that depicts the movement of carbon in the ecosystem.

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.
