Answer:
8. T= d/s = 139/13 = 11.1 seconds (rounded to 1dp)
9. d= sxt = 3 x 15 = 45m
10. d= sxt = 2.5 x 5 = 12.5m
Explanation:
Answer:
This question lacks options, the options are:
A. The sequence of DNA determines the structure of lipids, which produce phenotypes.
B. The sequence of DNA determines the structure of proteins, which produce phenotypes.
C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.
D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.
The answer is B.
Explanation:
DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.
An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.
For an individual to have the behavioral expression of the disorder pku, the individual must inherit a recessive combination of alleles and be exposed to phenylalanine in the diet.
What is pku?
A rare genetic condition known as phenylketonuria, or PKU, causes the body to accumulate phenylalanine, an amino acid. The phenylalanine hydroxylase (PAH) gene is altered in PKU. The enzyme required to degrade phenylalanine is produced in part because to this gene.
When a person with PKU consumes protein-containing foods or aspartame, an artificial sweetener, a dangerous buildup of phenylalanine can occur because this person lacks the enzyme required to break down phenylalanine. This may ultimately result in severe health issues.
