The author supports the statement by explaining the different theories about yawning, this includes theories and some that are still studied.
The author states that scientists have not yet reached any consensus regarding theories about why humans yawn and argue this claim by explaining the following theories about yawning:
- In Antiquity: Hippocrates' Yawning Theory focused on the respiratory system by hypothesizing that yawning precedes fever and is a way of removing polluted air from the lungs.
- In the seventeenth and eighteenth centuries: Most theories focused on the circulatory system. These theories posited that yawning causes an increase in blood pressure, heart rate, and oxygen in the blood.
- Today: Dr. Robert Provine, in 2005 stated that yawning is associated with changing a state of behavior.
- Gallup in 2008 proposed that yawning is related to a way of cooling the brain's temperature.
- In 2011, Dr. Andrew Gallup and Omar Tonsi Eldakar stated that yawning is related to the outside temperature, that is, when the temperature is warm, the body yawns less frequently.
According to the above, it can be inferred that scientists have not reached a consensus on yawning because all have raised different theories to explain its function.

Answer:
percent
Explanation:
Dystrophia myotonica protein kinase gene, DMPK is a kind of autosomal dominant mutation. Since this disease is autosomal, it is not affected by the sex chromosome. Out of total 23 chromosome pairs in human being, 22 are autosomal chromosome while one pair is sex chromosome. Also autosomal dominant means that the mutated gene is a dominant gene that is found in the non sex chromosomes.
Thus, only one mutated allele is required to pass on the mutation through the families hierarchy.
Thus, the mutation rate of the DMPK gene is
%
Answer:
the answer is selective permeability
Explanation:
A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar).
