The first thing to do is activate
EMS. Use cool or cold water to cool the burn for 10 minutes as soon as
possible. ( Do not use ice or frozen compress.) Early cooling will minimize the
depth of injury and decrease pain. Remove jewelry near the affected area. Cover
the injury with dry, clean pad loosely
to protect it. Do not give food or drink to injured person. Keep him comfortable
until EMS arrives and takes over.
Ii thinks they get there energy from proteins
Answer: A. scalp hairs grow constantly throughout life.
Explanation:
Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".
The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.
Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).
Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.
Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
Answer:
A and D
Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.
If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:
- Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
- The normal synthetase might be present but not in an adequate amount.
