Options for the question have not been given. They are as follows:

type of soil

type of plants

exposure to sunlight

method for measuring the growth

Answer:

exposure to sunlight

Explanation:

A scientific experiment has an experimental group and a control group. Control group is included to omit any error in results due to the factors other than the variable factor. Experimental group is the one exposed to different levels of the variable factor.

Here, Carlo wants to determine the the effect of day length on plants' growth. The test variable here is thus the duration of sunlight. In experimental group, this duration will be changed to determine its effect. In control group it will be kept constant so that results from other factors can be excluded from the observed experimental result.

Answer:

c. The flea beetle can become an invasive species

Explanation:

An invasive species is a non-native species that is introduced to the population (for example by humans). Because they are non-native, they can disrupt the 'natural order' of things. I.e., they can change the function of the ecosystem, which develops naturally to result in a harmony.

In this example, the leafy surge is a good example of an invasive species, it was accidentally introduced and has grown out of control, damaging the range land. In an attempt to control this, we deliberately introduced <em>another non-native species</em>.

This is in an attempt to fix the original mistake. If it works, then great! But if the flea beetles don't actually eat the leafy spurge, and they reproduce so quickly... it means we have introduced an additional species that could also disrupt the ecosystems. This could then mean that the flea beetle becomes an invasive species.
