He wondered, Does the position of the pot determine the growth of the stem?<span>
He hypothesized that the plant’s stem grows perpendicular to the soil.
</span><span>To test his hypothesis, Brian placed the pot horizontally. He checked the plant after two weeks.
</span>
<span>Brian observed that a plant’s stem grows against gravity.
</span><span>On analysis, Brian found that the plant grew parallel to the soil. He modified the hypothesis, and then retested the experiment.
</span><span>Brian communicated the results to his science class.</span>
I'd go with A. can interact to influence a trait, such as eye color
In this question, there are no options given to choose from. So i would answer this question based on my knowledge. The most likely cause of the observed variation is adaptation and evolution. The birds of that island adapted to the food source and then they evolved as per the requirement of the place and food source.
The answer is most likely c
Answer:
C. The trout population decreases as oxygen levels decrease.
Explanation:
We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.
The other options are incorrect because we can actually see that for...
A; the population of whitefish actually decreases as oxygen levels also decrease.
B; the population of carp actually increases significantly as sewage levels increase.
D; the walleye population actually also decreases overall as sewage levels increase.
