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

If a particular cell is known to be round and incapable of producing its own food, which one of these organelles would you assum

UNO [17]

If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:

CENTRAL VACUOLE
plasma membrane
cell wall
chloroplast

The correct answer as to which of the organelles the cell must have would be the plasma membrane.

central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
All cell types have plasma membrane.

Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.

Describe the digestive process?

babunello [35]

Explanation:

Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.

Which water pollutants can lead to excessive growth of water weeds

pychu [463]

Answer: Water pollution also affects the ecosystem – it can cause a phenomenon called eutrophication. This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.
