Answer:
B. Herbicides
Explanation:
Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.
Mowing, net barriers and inspections are mechanical controls.
Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.
The use of herbicides is a chemical control of plants that grow where they are not wanted.

The Complex nth Roots Theorem with any nonzero complex number has exactly n ∈ N distinct nth roots.
<h3>
What is a non-zero complex number?</h3>
This is the quantity which does not equal zero is said to be nonzero. A real nonzero number must be either positive or negative, and a complex nonzero number can have either real or imaginary part nonzero.
The roots lie on a circle of radius centered at the origin and spaced out evenly by angles of 2π/n.

The distance of the object from the mirror is 3cm.
To calculate the distance of the object from the mirror, we make use of the mirror formula
<h3>Mirror formula</h3>
- 1/f = (1/u)+(1/v)............ Equation 1
Where:
- f = Focal length of the mirror
- v = image distance
- u = object distance.
Using the real is positive convention,
Given:
Substitute these values into equation 1 and solve for u
- 1/5 = (-1/10)+(1/u)
- 1/5+(1/10) = 1/u
- 1/u = (2+1)/10
- 1/u = 3/10
- u = 10/3
- u = 3.33
- u = 3 cm
Hence, The distance of the object from the mirror is 3cm.
