1.)When evaluation was first processed which of the following was used as evidence to suport the idea (1 point)
a.)observations of nature****
b.)laboratory experiments
c.)extensive fossil collections
b.)genetic sequence
2.)a farmer sprays insecticide on his crops and notices that the insect pest problems disappear. a year later he tries the same insecticide only to find that he did not achieve the same result. the insect population shows resistance to the insecticide. This is an example of acting on a population to change its characteristics. this is an example of____
idk number 2 and i really need help
but my answer for #1 is a mrs.sue please help
suspect you mean evolution on which case I would vote for a) with Darwin
genetic adaptation http://grapes.msu.edu/integrated_pest_management/how_pesticide_resistance_develops
For question 1, you correctly identified the answer as a.) observations of nature. Observations of nature were initially used as evidence to support the idea of evaluation.
To understand why this is the correct answer, let's break down the other options:
b.) laboratory experiments: While laboratory experiments are valuable in evaluating hypotheses, they were not the initial evidence used to support the idea of evaluation. Observations of nature preceded the use of laboratory experiments.
c.) extensive fossil collections: Fossil collections provide insights into the history of life, but they were not the primary evidence used to support the idea of evaluation. Again, observations of nature were more foundational.
d.) genetic sequence: Genetic sequencing is a modern tool that was not available when evaluation was first established, so it could not have been used as evidence at that time.
Moving on to question 2, we are presented with a scenario where a farmer sprays insecticide on his crops and initially observes a positive outcome, but a year later, the insect population shows resistance to the insecticide. This is an example of acting on a population to change its characteristics.
The phenomenon described here is known as insecticide resistance. Insecticide resistance occurs when a population of insects evolves or develops the ability to survive exposure to a particular chemical insecticide. This is a specific form of natural selection where the individuals within a population with genetic variations that make them less susceptible to the insecticide are more likely to survive and reproduce. Over time, the resistant individuals become more prevalent in the population, reducing the effectiveness of the insecticide.
So, the answer to question 2 is: insecticide resistance.
