Answer:

(Answers may vary.)

There are two classes of soil remediation: in-situ and ex-situ.

In in-situ remediation, there is no excavation of the contaminated soil. This remediation is an economical way of cleaning up. However, it takes a long time for the treatment to be effective. In addition, the treatment is not uniform because of variability within soil and difficulty in monitoring remediation progress.

Ex-situ remediation involves excavating a contaminated area. In this method, the soil is either treated on the same site or transported to a remote site for cleaning. This type of remediation is complex and expensive, but very effective. It involves the following:

homogenization of the contaminated soil before treatment

monitoring to ensure that the soil is cleaned to the required level

Read the following scenarios carefully and explain how natural selection will occur in each.
IrinaK [193]

Answer:

The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.

Explanation:

Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.

In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.
