Which of the following is not an essential part of anatomical position?
- a. feet together
- b. feet flat on the floor
- c. palms forward
- d. mouth closed
- e. arms down to the sides

Introduction:
The anatomical positions are important in identifying the location of body parts. Based on the anatomical position, it is called as posterior, ventral, anterior, dorsal, superior, medial, inferior, proximal, and so on.
Answer to Problem 1TYR
Correct answer:
Keeping the mouth close is not considered as anatomical position. Therefore, option dis correct.
Explanation of Solution
Justify reasons for the correct statement:
When the mouth is closed, it makes a voluntary movement and it could not be taken as an anatomical position. Anatomical position should be of involuntary movement.
Option (d) is given as, “mouth closed”.
While standing in an anatomical position, one must open the mouth a little wider.
Hence, option (d)is correct.
Justify reasons for the incorrect statements:
Option (a) is given as, “feet together”.
While standing in anatomical position, the knees should touch each other on the lateral side and feet should be together by touching at the ankles. Hence, it is a wrong answer
Option (b) is given as, “feet flat on the floor”.
In anatomical position, while standing upright, the feet should be flat on the floor by touching each other at the ankles. Hence, it is a wrong answer.
Option (c) is given as, “palms forward”.
While standing upright in anatomical position, elbow should touch the adjacent of the torsoand the palms should be facing forward with fingers open.Hence, it is a wrong answer.
Option (e) is given as, “arms down to side”.
While standing in anatomical position, the arms should be touching the sides of the torso and it should be let freely down with palms facing forward. Hence, it is a wrong answer.
Hence, options (a), (b), (c), and (e) are incorrect.
In anatomical position, all the body parts must be able to identify easily.

- 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.
