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
Answer:
100 per 100,000
Explanation:
B. ribosomes
C. mitochondria
Answer:
Option B, Ribosomes
Explanation:
Ribosome exists in both free state and also as a membrane bound organelle. Thus, ribosomes is found in both the eukaryotic and prokaryotic cells as it is an essential component that facilitates the translation of RNA and formation of protein.
Golgi apparatus and mitochondria are membrane-bound organelles and all membrane-bound organelles are found in eukaryotes only. Prokaryotes do not have membrane-bound organelles
Thus, option B is correct
B) it gets more direct sunlight.
C) the Earth is closer to the Sun.
D) it is tilted away from the Sun.
Answer:
Option (B)
Explanation:
When the tilt of the earth is towards the sun, then it is called summer in the northern hemisphere. In this position, the sunlight is directly over the earth, as a result of which it absorbs more amount of heat. Spring is the season that starts from about 21st March to 21st of June or it can be considered as the season that exists between the summer and winter. Here, a high amount of sunlight is absorbed due to which the temperature eventually rises.
This is the reason why the northern hemisphere is relatively warmer during the spring season than in winter.
Hence, the correct answer is option (B).
