Onion roots are treated with a protein. The control group is compared to the treated group. The number of cells found at each phase of mitosis is determined. Calculate chi-square and explain what this means as it relates to the null hypothesis. Note the P-value at 0.5 = 3.84.

Answers

Answer 1

Interphase: (450 – 467)^2 = 289 /467 .618

Mitosis: (159 – 170)^2 = 121/170 = .711

Chi square = 1.329

The null hypothesis would be: if treated with the protein, the onion root remains the same. Based on the chi-square value of 1.329, this value is less than the critical value of 3.84. This means we can accept the null hypothesis. In other words, the untreated cells are no different from the treated cells regardless of which phase of mitosis you are viewing.

Answer 2

Answer:

Sample Response:

Chi-square = StartFraction (o minus e) Superscript 2 Over e EndFraction

Interphase: (450 – 467)2 = 289 /467 .618

Mitosis: (159 – 170)2 = 121/170 = .711

Chi square = 1.329

The null hypothesis would be: if treated with the protein, the onion root remains the same. Based on the chi-square value of 1.329, this value is less than the critical value of 3.84. This means we can accept the null hypothesis. In other words, the untreated cells are no different from the treated cells regardless of which phase of mitosis you are viewing.

What three notes (in solfege) make up the TONIC TRIAD in a major key?

Answers

Answer:

The A major scale is A, B, C#, D, E, F#, G#. The second note is B, so that's the root of the supertonic ("above the tonic") triad. A triad built on B and using the above scale notes would come out as B, D, F# (remember that a third covers three note names, so B to D makes a third and D to F# makes another).

What is: 5g + 3( -4 + 4g) = 1 - g

Answers

Answer:

Let’s start by using:

Parenthesis
Exponent(s)
Multiplication
Division
Addition
Subtraction

Parenthesis always come first, and since we do have parenthesis in this equation, we need do what’s inside the parenthesis first!

First, write out the entire equation.
5g + 3(-4 + 4g) = 1 - g

Next, follow the PEMDAS rule(s) and you should eventually get the full, correct answer.

Now, do keep in mind that in order to do what’s in the parenthesis you may have to multiply, *cough, cough*, divide, add, etc. first!

People have had both positive and negative reactions to Angela's Ashes. Why do you think people have reacted so strongly to McCourt's memoir? Identify three topics or subjects you anticipate you will find detailed within the pages of this piece.

Answers

Answer:

Because his memories present very strong and impacting concepts, but controversial at the same time.

Explanation:

Angela's Ashes is a book that tells the memories of McCourt during his childhood and adolescence. His memories depict very strong and uncomfortable situations to be experienced, such as negligent parents, depression, alcoholism, extreme poverty, exploitation, sexual experiences, poor self-esteem, among others.

The experiences lived by McCourt are not comfortable to be read. Some people think that this is a positive point of the book's narrative, because it shows how dirty and uncomfortable human life is. However, many people criticize this type of narrative, because they claim that it is exaggerated and that it suffers from suffering. In addition, many people, like McCourt's mother, claim that these memories are false and fanciful, which increases the discrepancy of opinion among readers.

Who is an tutor?

A tutor is someone who provides individual or small group instruction. Tutoring's goal is to help students help themselves, or to assist or guide them to the point where they are an independent learner and no longer require a tutor.

Learning is a process that frequently involves failed attempts. Learning and problem solving necessitate a period of sorting through facts and options in order to achieve success.

Therefore, when using a tutor, a student may not learn in the first sessions, but will slowly start learning the lesson.

What happened in the 1980's with environmental laws and regulations because some people claimed that the laws and regulations were hurting the economy?

Answers

Answer:

James Carter enacted strict laws that limited the exploitation of natural resources, limited the use of non-renewable energies and increased the size of environmental reserves.

Explanation:

In the early 1980s James Carter turned his administration over to a policy with a strong environmental bias. He started by hiring influential environmentalists to hold some government positions, in addition to asking them for constant advice on nature, its exploitation and the degradation that could occur.

As a result, he enacted numerous laws that exercised serious environmental protection regulations, limiting their exploitation, the use of non-renewable energy, the burning of fossil fuels, in addition to doubling the areas of environmental reserves and areas of environmental protection. This had a bad effect on businessmen, who claimed that these regulations reduced the factors of production necessary for the manufacture of goods and services and, therefore, hurt the economy.

The need for legal action to address the grave inconveniences that might result from the labor shortages described in the passage most likely resulted from

Answers

Answer:

The agrarian nature of medieval European economies and their reliance on coerced labor.

Explanation:

The passage is a letter from King Edward III of England which was written in the year 1351. He stated in the letter that the nation was just recovering from a pestilence that had debilitating effects. The farmers who were mostly slaves were refusing to work unless they were given increased wages.

King Edward addressed this problem which caused "grave inconveniences" by stating in his letter that all slaves must be forced to return to their masters and that they were to be paid the wages agreed upon five years ago. He also stated that whoever refused to abide by this rule was to be confined to jail.

The need for legal action to address the grave inconveniences mostly resulted from the refusal of workmen to attend to their masters except they received more payments.

According to the passage,  the King of England acknowledged the labor shortage. The labor shortage was a result of the death of a lot of the workforce.

The grave consequences as used by the King means that the nation might be in trouble due to lack of workforce, especially the plowmen.

Explain how the landscape can modify climate.

Answers

Climate is heavily modified by the landscape. Where there are large mountain ranges, wind is deflected upwards causing rain on the windward side and a rain shadow on the leeward side. The biome that results from this is considerably different from the one that may have appeared with no wind deflection. Large expanses of ocean and flat land also change the climate by modifying air temperatures and the amount of rainfall.

Which best defines the relationship between short and long term goals?

Answers

Answer:

Short term goals are objectives set to be accomplished in less than one year. They are plans that will be fulfilled shortly. Short term goals are easy and less costly to achieve. Long term goals take longer than one year to accomplish. They require planning in terms of finances and management.

Long term goals are usually split into several smaller milestones for successful implementation and monitoring. For example,  owning a home is a long term goal. This objective can be split into several short steps. One of the steps will be saving for the deposit. These several steps are short term goals. Achievement of these short term goals will lead to the achievement of the long term goals. In other words, Long-term goals are split into short term objectives for better management and accomplishment.
