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.
During osmosis, a statement which correctly describes the movement of water across a selectively permeable membrane is: 3. Either of these descriptions is correct and equivalent.
<h3>What is osmosis?</h3>
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a selectively or permeable membrane from a region of high concentration to a region of lower concentration.
This ultimately implies that, the process of osmosis can be illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
In conclusion, the movement of water of from high water concentration to low water concentration and from low solute concentration to high solute concentration are statements which correctly describes the movement of water across a selectively permeable membrane during osmosis.

Complete Question:
Which of the answer choices correctly describes the movement of water across a selectively permeable membrane during osmosis.
1. The water will move from high water concentration to low water concentration.
2. The water will move from low solute concentration to high solute concentration.
3. Either of these descriptions is correct and equivalent.
The distance in miles from P to Q is 12 miles
<h3>Distances and speed</h3>
Let the distance from P to Q be "d"
Since the formula for calculating speed is expressed as:
For the distance of P to Q
40 = d/t
d = 40t
If he drives back at an average speed of 45mph and 2 mintes less, then;
45 = d/t - 0.033
d = 45 (t - 0.033)
Equating both distances
40t = 45(t - 0.033)
40t = 45t - 1.485
-5t = -1.485
t = 0.297
Get the distance from P to Q:
d = 40(0.297)
d = 11.88 miles
Hence the distance in miles from P to Q is 12 miles

Cutting at an angle increases the surface area where water can be absorbed, allowing the flower to thrive.
