Answer:
Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.
Nocturnal Behavior
These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves. They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more. In one year, a 100-bat colony can drink the blood of 25 cows.
During the darkest part of the night, common vampire bats emerge to hunt. Sleeping cattle and horses are their usual victims, but they have been known to feed on people as well. The bats drink their victim's blood for about 30 minutes. They don't remove enough blood to harm their host, but their bites can cause nasty infections and disease.
Hunting for Blood
Vampire bats strike their victims from the ground. They land near their prey and approach it on all fours. The bats have few teeth because of their liquid diet, but those they have are razor sharp. Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin. After putting the bite on an animal, the vampire bat laps up the flowing blood with its tongue. Its saliva prevents the blood from clotting.
Young vampire bats feed not on blood but on milk. They cling tightly to their mothers, even in flight, and consume nothing but her milk for about three months.
The common vampire bat is found in the tropics of Mexico, Central America, and South America.

Explanation:
The correct answer is Option B: 3%.
In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.
<h3>What is doubling time?</h3>
- The doubling time is the time taken by a population to double in its size.
- This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
- There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
- Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
- Here, Doubling time= 23.3 years.
- Growth rate= 70/23.3= 3%
