A class of biology students conducted an experiment on ants. Each group was randomly assigned 20 ants. Each ant was placed halfw

ay between food located down a dark-colored path and food located down a bright-colored path.
Five of the groups find that the ants choose the bright path more often. Three groups find that the ants prefer the dark path and two groups find no preference among their ants.
A student who hypothesized that ants are attracted to bright colors found that this hypothesis was supported by his group's data.
How is the student’s conclusion an example of bias?

Answer:

Because the repetition of the experiment yields different results when they are realized by distinct groups of students .

Explanation:

The students needs to repeat the experiment and increase the value of n (sample size) in order to obtain statistically significant results and thus confirm the working hypothesis.

<span>Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity. -------- Let's take a look at each option and consider them in light of our knowledge. 1. These compounds will combine into larger molecules as they interact in the nitrogen cycle and become food for fish and other animals, increasing biodiversity. * This has some problems. Yes, the fertilizers will cause an increase in the food supply, but that doesn't spontaneously cause an increase in biodiversity. The only way to increase the biodiversity is to introduce new organisms. And this isn't such a mechanism. I won't pick this choice. 2. The water cycle will remove excess fertilizer naturally through evaporation, with no impact on biodiversity. * There's some issues here as well. Think about how much fertilizer runoff is considered a pollution issue. If this option were true, then we wouldn't be seeing so many news articles complaining about fertilizer running causing pollution problems. So this answer isn't any good either. 3. Nitrogenous compounds will be recycled into carbon compounds to create new organisms and increase biodiversity. * Still running into the "spontaneous increase in biodiversity" issue here. How would more carbon compounds suddenly increase the biodiversity? This answer isn't any good either. 4. Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity. * This is a real problem. Some might think that "Algae is a plant. Plants produce oxygen. Why would more algae cause the oxygen supply to decrease?" Well, the answer is pretty simple. Individual algae cells don't live very long. So you have a log of algae being produced. Releasing oxygen to the air, and then dying. And the dead algae then proceeds to decay, which does consume dissolved oxygen in the water. Which does cause the death of fish and other animals that are dependent upon that dissolved oxygen. And that does reduce the biodiversity in the area. So this is a reasonable and correct answer.</span>

Alika [10]

I inferred you are referring to Violet instead.

<u>Answer:</u>

<u>she chews "Gobstoppers" which are not meant for chewing.</u>

Explanation:

Remember, it all started when Violet entered the inventing room and she began to show an interest in gobstoppers, believing them to be similar to gum, even though they were not meant for chewing.

After ignoring the warning from Wonka, she begins chewing the gum which leads her body to swell.

Alysha wants to test the effect of different materials on the melting rate of ice. She finds the initial mass of four pieces of
Tanzania [10]

Answer:

In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.

Explanation:

During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.

In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.

olasank [31]

According to the theory proposed by Harry Hess, what causes continents to move?

The correct answer is : seafloor spreading.

Earlier, in 1912 Alfred Wegener produced evidence that the continents are in motion but this idea was shelved as he could not explain what forces the continents to move. So, almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.
