A construction company recently filled in a local pond to build new houses. Duringthe following weeks, a local scientist noticed a decline in the mosquito population in
the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?
A. a three-month case study observing the behavior of animals that depend on
mosquitoes for food
B. a survey asking residents about their observations of the local mosquito
population
C. a collection device in the area that counts the number of mosquitoes caught
weekly
D. a controlled lab experiment with mosquitoes that limits watercolor the
experimental group

Answer 1
Answer:

Answer: (C.) a collection device in the area that counts the number of mosquitoes caught

weekly

Explanation: I took the test :D
Answer 2
Answer:

Final answer:

The most suitable research method for measuring a change in the mosquito population due to construction would be 'a collection device in the area that counts the number of mosquitoes caught weekly'. This method provides quantifiable, reliable data over the three-month study period.

Explanation:

To thoroughly study the change in the local mosquito population due to the construction, the most suitable research method for the scientist would be to use 'a collection device in the area that counts the number of mosquitoes caught weekly' (option C). This method would provide direct, quantifiable data about the mosquito population, showing changes on a weekly basis over the three-month study period.

A case study (option A) would not provide direct data about the mosquito population. Instead, it would provide indirect observations through the behavior changes of animals that prey on mosquitoes. Similarly, a survey (option B) relies on residents' subjective observations, which may not be reliable or accurate. Finally, a controlled lab experiment (option D) does not account for the plethora of variables present in a natural environment, thus limiting its effectiveness in this situation.

How many double bonds are in an alkane?

Answers

None
Alkanes only have single bonds

Final answer:

Alkanes are hydrocarbons with only single bonds between the carbon atoms, therefore, they do not contain any double bonds.

Explanation:

In chemistry, an alkane is a type of hydrocarbon where all of the carbon-carbon bonds are single bonds, meaning they share just one pair of electrons. Double bonds share two pairs of electrons and are typically found in alkenes, a different type of hydrocarbon. Therefore, an alkane does not have any double bonds.
