Answer:
3+9 = 12
Explanation:
A <em>"counterexample" </em>is an example that shows the falseness of a statement.
Among the choices above,<em> 3+9 = 12</em> is the ideal counterexample. Its sum is an even integer (12); however, its addends are odd integers (3 and 9). So, this goes against the statement above.
The<u> first choice</u> (6+10 = 16) is clearly not a counterexample, but an example of the statement. The <u>second choic</u>e (14+9=23) is not a counterexample because its product is an odd integer, not an even integer. The statement is referring to the condition of an even integer for an answer.

The answer is - adiabatic lapse rate.
Adiabatic lapse rate refers to the rate at which the air expansion cools. For the dry air it has the value of 9.8 degrees per kilometer. When the air that is saturated starts rising and cools, the process of condensation of water vapor begins, releasing latent heat in the process.
Answer: Based on the provided information, the chemical will help the black walnut trees compete with plants growing nearby By suppressing the growth of the other plants.
What are non toxic chemicals?
Non toxic chemicals can be regarded as these chemicals that are not harmful to the plant.
According to this question, we were informed about Black walnut trees that produce a nontoxic chemical that becomes highly toxic when it is exposed to air or soil.
As a result of this we can see that the growth of other plants will be affected as a result of the chemical by the first plant.
Therefore, option B is correct.
