Answer:

b. grasshopper effect

Explanation:

Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.

When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.

According to natural selection process, the trend that will occur is that the number of organisms with harmful characteristics will decrease  while organisms with neutral or beneficial traits will increase in the plant population

<h3>What is natural selection?</h3>

Natural selection is the process by which organisms with favorable features and characteristics that enable them to adapt to their environment survive while those with unfavorable traits die off.

In a changing environment, it will be observed that the organisms with the most favorable traits will be the most dominant in the environment.

Therefore, for the Year 5 and Year 10, the most likely trend that will occur is that the organisms with harmful characteristics will be decreasing in the plant population while organisms with neutral or beneficial traits will likely be increasing in number.

Amiraneli [1.4K]

According to the question, the amount of the drug administered is 250 milligram (mg). The available dose of the drug is 250 mg per 1.5 mL (milligram). So, for the administration of the 250 mg drug, 1.5 mL of the available drug concentration should be used.

We need to determine the amount of the drug must be drawn in cc (cubic centimeter).

1mL = 1cc

As

1.5 mL = 1.5 cc

So, the amount to be drawn is 1.5 cc.
