To determine:
The difference between observation, inference and skepticism.
Introduction:
Science is a systematic study which builds and organizes knowledge in the form of testable explanations. It is the application of knowledge for understanding the various phenomenon by following a systematic methodology. The methodology involves observation, classification, using numbers, measurement. The various methods employed for reasoning are universal in nature.

Explanation of Solution
Observation: The observation can be defined as something that is experienced by a person. For example, if a person can touch, feel, smell, see hear, calculate and experiment of something, the experience of the person will be referred to as observation.
The inference can be defined as an idea, which is deduced from reasoning and evidences are present for the belief. and reasoning. It is an educated guess.
The skepticism is a belief that is not supported by the evidences, nor it is an educated guess. It is a popular belief which is followed or practiced for long time by a group of people or an individual.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
