Answer:

If I were to choose a plant or animal which is interesting, I'd choose the "cactus."

Explanation:

A "cactus" is truly a splendid plant owing to its ability to survive in the desert or periods of drought. Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.

One of these threats is the "over-collection of cacti." Due to its versatile use, the cactus is often sold as an ornamental plant.
Another threat is the number of pests, such as snails and slugs, that attacks it yearly. It is a delicious food for mealy bugs, red spider mites, gnats, flies, etc.
People often misunderstand the cactus' water level needs. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.

What evidence can be examined when determining common ancestry amongst hominids?

mars1129 [50]

We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.

Complete Question

There were 100 new cases of syphilis last year in a given population of 100,000 people. At that time, 500 people in this population already had syphilis. The incidence of syphilis in this population is __________.

a. 100 per 100,000

b. 500 per 100,000

c. 1000 per 100,000

d. 5000 per 100,000

Answer:

a. 100 per 100,000

Explanation:

Incidence rate of a population can be defined as the rate at which an disease occurs in a population.

The incidence of a population is calculated as

The number of new cases ÷ The population of the people

From the above question,

The number of new cases = 100

The population of the people = 100,000

The incidence = 100 ÷ 100,000

The incidence of syphilis in the population is 100 per 100,000
