B) because pesticide salesman need to make more money
C) because plants begin to eat the pesticides
D) because the explosive growth of the human population places increased demands on current farmers
Answer:
Why do humans need more potent pesticides over time?
because the target population soon develops a resistance to the chemical
Explanation:
Over time when pest are exposed to pesticides to much, at a point in time they will develop resistance which calls for change of pesticides application.
Answer:
A. Because the target population soon develops a resistance to the chemical
Explanation:
I believe this is the correct answer here because it would be similar to how humans develop tolerance for medicine and illicit drugs; over time, we would need more and more of the drug to achieve the same result. It is also logical. B and C are definitely not correct nor are they logical, and D is not logical either; human population growth does not influence current farmers that much, and even if it did, humans would not need a higher quality of pesticide, just a higher quantity.
B) It is based on European measurement standards.
C) It is the only scientific measurement system.
D) It is based on the wavelength of krypton-86 radiation.
Answer:
The answer is:
A) Its measures are based on divisions that are powers of ten.
Explanation:
The explanation for why this is the answer is that it is true and obvious that the metric measurement system relies on certain divisions and prefixes that are based on the powers of ten such as "centi-" or "milli-". In short, the metric measurement system's basis is being able to have it's measures somewhat "altered" or "adjusted" by these particular prefixes to fit the item or subject or object being measured.
yes it is very true, if that's your question
B a star
C a nebula
D the sun
E the force of gravity
Answer: Option 'B' is correct.
Explanation:
All the iron molecules that are in your body were originally created by a star.
During a star supernova, a very large amount of energy and neutrons are released by stars which allows heavier elements to be produced.
And when there is explosion of star occurs, those elements are found which is used to make DNA and DNA contains large amount of iron molecules.
Hence, Option 'B' is correct.
I think the answer is B - a star! Hope this helps!
