Answer:
Genetic mutation.
Explanation:
Insects may grow used to the effects of pesticides over time (natural selection), causing their genetics to be stronger than the pesticides, while eagles (having nothing to do with pesticides, because they typically live in the air) would be affected because the presence of the chemicals are new to its genetics.
Answer:
Bugs have evolved over time to be immune.
Explanation:
Through the process of natural selection, insects will become immune to the effects of chemical spray, while an eagle that hasn't ever been exposed to such chemicals would be harmed significantly more.

Add a few toy houses in various places along the riverbank in your model. Your houses should be on top
of the sand, and directly on the river's edge. Describe what happens to the houses over time as the water
flows through the river. Based on your observation, describe the negative impact erosion can have on
human settlements around rivers.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.

If an organism's DNA contains 33% adenine nucleotides and 17% guanine nucleotides, what percentage of its DNA is composed of cytosine nucleotides
A DNA with 33% adenine and 17% guanine nucleotides respectively will contain 17% cytosine.
Purine to Pyrimidine ratio in DNAAccording to Chargaff's rule, the ratio of purine to pyrimidine bases in DNA is constant.
Since adenine always pairs with thymine and guanine always pairs with cytosine, adenine to thymine and guanine to cytosine ratios would be constant as well.
Thus, if a DNA contains 17% guanine, it will also contain 17% cytosine.
