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:
8A
Explanation:
I= Q/t, where
I= current (A)
Q= charge (C)
t= time (s)
First convert the time from minutes to seconds.
1 minute= 60 seconds
2 minutes= 2×60= 120 seconds
Using the formula,
I= 960÷120
I= 8A
48 because the formula for work is w=f•d so when you plug f and d in its 12 times 4, giving you 48.
Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.
