1. A disease cause by a very small genetic change. Most cases result from the deleting of three bases in a gene for a protein called cystic fibrosis transmembrane changes which in a gene's DNA sequence can change proteins by altering their amino acid sequences which may affect one's phenotype.

<span>Severe
Several methods to assess the severity of psoriasis are available including Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA) for psoriasis, and the National Psoriasis Foundation Psoriasis Score (NPF-PS). In terms of body surface area, psoriasis is generally classified as mild when it affects less than 5% of the body, moderate when it affects 5-10%, and severe for >10%. Based on PASI, which includes a rating or score for the surface area of the body affected by psoriasis, the "Area Score" would be 2.

The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
<h3>What is an hypothesis?</h3>
Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.
An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.
According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.
The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
