In this task, you’ll record the direction of a compass as it’s placed at different points around a magnet. The investigation will try to answer the question, Do two magnets create magnetic force fields that allow them to interact without touching?
Part D :
How might someone dispute the results of this investigation? How might you counter the argument?

Answers

Answer 1

Answer:

It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.

There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.

For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.

So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.

A conservation biologist is working to protect elephant seal populations. Elephant have a classic type I survivorship curve with very low levels of juvenile mortality and high survivorship rate. They insist that reducing threats to adults is more important than protective juveniles. Are they correct

Answers

Answer:

Elephants and Classic Type I Survivorship Curve

The conservation biologist is correct.

Explanation:

Classic type 1 survivorship curve means that mortality of elephants increases as they age, and their fecundity (or fertility) decreases as they age.  Therefore, reducing the threats to adults should be more important than protecting the younger elephants.  The younger elephants have higher rates of survival and fecundity than their older parents.

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.

Answers

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Which of the following statements are true about a healthy individual without Prader-Willi or Angelman syndrome? ( Choose two answers)
a. Maternal and paternal copies of SNRPN are expressed at the same level in heart cells.
b. The maternal and paternal copies of UBE3A are differentially expressed in bone cells.
c. The maternal copy of SNRPN has DNA methylation at its promoter in liver cells.
d. Expression of the paternal copy of UBE3A is silenced in neurons.

Answers

Answer:

The correct answer is - A and D.

Explanation:

Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.

It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.

ANOVA is a technique that permits the comparison of the equality of means for multiple populations. Thus, 3 means could be compared and a determination of whether or not one of the means is significantly different from others can be made. This technique is extremely useful, but, as is always the case, the application requires a firm understanding of models assumptions. Consider the following scenario. A meticulously determined random sample of 200 observations is taken from a very large population. This data divides into 4 groups or factor levels, and a numerical measure for each observation is recorded. The population distribution of the measure appears to be slightly skewed positive. The 4 groups have the following number of observations 30, 100, 15 and 55. Which of the following statements leads to the greatest concern in using ANOVA as an analytical technique.
a. Unequal sample sizes among groups can seriously affect the power of the test.
b. Slightly skewed positive distribution of population measures seriously affect the power of the test.
c. In this scenario, I should be concerned about whether the data has been gathered in a biased fashion.
d. Four is not a sufficient number of groups into which to divide the data.

Answer:

Gandhi, was a leader in India who worked to end British rule. He led India to independence and inspired many to non-violent forms of protest and resistance. He fought to end poverty, worked to expand women's right to vote, and built bridges between ethnic and religious groups. Like Thoreau, he lived simply, owned very little, and ate a vegetarian diet. In India, Gandhi's form of protest was called the "non-cooperation movement." He urged Indians to boycott British education systems and leave government jobs. The movement was very popular, and in part to stop its spread, the British controlled government arrested him. After a few years, he was released and became active in politics again. He inspired many to follow him on marches to protest various taxes. On one such march, thousands followed him 240 miles over 24 days to the sea to protest a salt tax. This march set the example of non-violent resistance to the government that others in the country followed. Eventually India won independence from Britain, in large part because of Gandhi work.Gandhi's model of resistance and reform was creative, appealing, and successful. As a result, Dr. Martin Luther King looked to Gandhi when the time came to find a way to resist segregation in the South. The lunch counter protests, famous for the passive response to anger, and even violence, aimed to end the separation enforced by laws in some regions of the South. King also organized walks, marches, and bus rides that were meant to bring attention to the issues facing African Americans. These forms of protest were directly modeled on Gandhi's, but King took them straight to the source of oppression. Where Gandhi's protests created awareness and built momentum, King's protests were in the face of great hatred and fear. The passive, non-violent protests were ultimately effective, mainly because the passive response to violence cast the opposition as brutes. However, change came slowly and at the cost of many lives. King remained committed to peaceful protest, however, until his death. King learned from Gandhi, expanding on what worked, applying old techniques to a new problem. Gandhi owed his philosophy, in part, to a New England poet who loved the woods.Based on the bolded paragraph, which line shows the success of Gandhi work? Eventually India won independence from Britain, in large part because of Gandhi work.
