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.
Answer:
Example of Chemical Control of Non-native species.
B) Herbicides
Explanation:
In the given options, all of them are can be used to remove or control non-native species. but among them only Herbicides is the chemical solution to control non-native species.
Herbicides are chemicals that are used to kill unwanted plants, which can be taken as non-native species.
Some of the herbicides kill the unwanted plants while leaving the desired crops unharmed, some interfere with the growth of such species while some kill all the plant material with which they come in contact with

Which is a disaccharide
Answer:
Sucrose
Explanation:
Sucrose is a dissaccharide that is made up of glucose and fructose
Antonio's toy boat is bobbing in the water next to a dock. Antonio starts his stopwatch, and measures the vertical distance from the dock to the height of the boat's mast, which varies in a periodic way that can be modeled approximately by a trigonometric function.
The vertical distance from the dock to the boat's mast reaches its highest value of -27cm every 3 seconds. The first time it reaches its highest point is after 1.3 seconds. Its lowest value is -44cm.
Find the formula of the trigonometric function that models the vertical height H between the dock and the boat's mast t seconds after Antonio starts his stopwatch. Define the function using radians.
What is the vertical distance 2.5 seconds after Antonio starts his stopwatch? Round your answer, if necessary, to two decimal places.
Answer:
Formula of the function is found:
[tex]H(t) = 8.5cos(\frac{2\pi}{3}(t-1.3))-35.5[/tex]
For t= 2.5s , vertical distance is:
H(2.5) = +42.38cm , H(2.5) = -42.38cm
Explanation:
General form of trigonometric function H(t) is given by:
[tex]H(t)=Acos(B(t-C))+D[/tex]
Where
A = Amplitude
Period = 3s = 2π/B
B = 2π/3
C = Phase shift = 1.3s
D = Vertical Shift
Find A (Amplitude):
Amplitude = (highest value - lowest value)/2
Amplitude = (-27-(-44))/2
Amplitude = (-27+44)/2
Amplitude = 8.5
Find D (Vertical Shift)
Vertical shift can be found by finding midpoint
Midpoint = (highest value + lowest value)/2
Midpoint = (-27-44)/2
Midpoint = -35.5
Substitute the values of A,B,C,D in the general form of trigonometric function.[tex]H(t)=Acos(B(t-C)) +D[/tex][tex]H(t) = 8.5cos(\frac{2\pi}{3}(t-1.3))-35.5[/tex]
which is the formula of the function
For t = 2.5s[tex]H(2.5)=8.5cos(\frac{2\pi}{3}(2.5-1.3))-35.5 \\H(2.5)= +42.38 {cm} ,H(2.5)=-42.38cm[/tex]
