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".
With ideal environmental factors, bacteria are able to reproduce at a very rapid pace.
<h3>Bacterial reproduction</h3>
Bacteria reproduce mainly by a single cell dividing into two, given the right condition. In order words, they reproduced by binary fission.
When environmental conditions are optimum, a typical bacterial cell can divide every 4 to 20 minutes depending on the species.
The time can become longer with sub-optimal environmental conditions.
