Answer:
Increased global temperatures, leading to a 20% reduction in rainfall
Explanation:
According to this question, forest fires are becoming rampant in tropical rainforests. Although this occurrence is natural, tropical rainforests do not typically undergo this natural process due to the average yearly amount of rainfall. This means that the high amount of rainfall in tropical rainforests help prevent or reduce the high cases of forest fire incidence.
However, the recent increased occurrence of tropical rainforest fires is most likely attributed to an INCREASE IN GLOBAL TEMPERATURES, LEADING TO A 20% REDUCTION IN RAINFALL. This is because an increase in the global atmospheric temperature causes the reduction of the amount of rainfall, which naturally helps curb the occurrence of forest fires.
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".
