Answer:
Explanation:
Lipids also come from foods, most commonly in the form of cholesterol or triglycerides. Certain kinds of essential lipids are often present in vegetable oils and legumes, as well as the cell membranes of just about every living thing.
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
