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.
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 is current sitution for he UK in regard to Brexit?
Answer:
Immediately after Brexit day - on 31 January - the UK went into a transition period with the EU. This was to give both sides breathing space to agree the new arrangements.
During transition the UK is still following EU rules and trading in the same way as before. However, the UK is no longer part of the EU's political institutions - so there are now no British MEPs in the European Parliament.
This transition period will last until 31 December 2020, when the new EU-UK relationship will begin. The deadline for extending the transition has now passed.

3 reasons forensic investigators need good observation skills.
Answer:
Forensic investigators look through a crime scene, finding physical evidence of a crime (blood, weapons, ect.) and therefore, need good observational skills to find these items. In addition to finding this evidence, more observations are required to determine what they mean in the crime. These same skills will also be needed to observe how these items correlate with the suspects to the crime, such as a finger print matching one of the suspects.
Explanation:
I googled what a forensic investigator was, and went off of that :|
The ability to recognize how these materials relate to the suspects in the crime, such as when a fingerprint matches one of the suspects.
As defined by the legal requirements of admissible evidence and criminal procedure, forensic science, also known as criminalistics, is the application of science to criminal and civil laws, primarily—on the criminal side—during the criminal inquiry.
To locate tangible evidence of a crime (blood, weapons, etc.), forensic investigators search through a crime scene.
To do this, they must have good observational abilities. More observations must be made in order to interpret them in the context of the crime in addition to finding this evidence.
The ability to recognize how these materials relate to the suspects in the crime, such as when a fingerprint matches one of the suspects, will also be required.
Thus, the ability to recognize how these materials relate to the suspects in the crime, such as when a fingerprint matches one of the suspects.

The recommended daily intake of vitamin C is 60. mg per day and there are 70. mg of vitamin C per 100. g of oranges. If the average orange has a mass of 85 g, how many oranges would you have to eat each day to meet this daily requirement? Round your answer to a whole number.
Answer:
1
Explanation:
1 orange = 85 g
x oranges = 100 g
100 *1 = 85x
x = 100 / 85 = 1.764 oranges.
1.764 oranges = 70 mg vit C
x oranges = 60 mg
1.764 * 60 = 70 x
70.588 mg = 70 x
x = 70.588/70 = 1.0084

Write a paragraph of at least 250 words analyzing the rhetorical strategies Goodall uses to develop her argument.
Jane Goodall wrote a very valuable article called "I Acknowledge mine" where she argues about exploiting animals and the need to ensure respect for animal rights. In this article Goodall condemns the practice of using chimpanzees in bio-scientific research, as well as emphasizing the importance of the human race in maintaining the safety and well-being of animals.
To present the argument efficiently Goodall makes use of the rhetorical strategic ethos, pathos and logos. She uses pathos when she shows the suffering these animals go through, when they are used to promote scientific advancement from which they will not usurp, even going so far as to die in the process. In this way, it appeals to people's emotions so that they have empathy for the cause of the chimpanzees.
She uses ethos, showing that we, as rational human beings capable of distinguishing the correct from the incorrect situations, must impose ourselves and demand that biomedical companies respect animal rights and not use them in irresponsible ways that cause pain and suffering to they. In this way, it appeals to the ethical values of readers.
Finally, she uses the logos, showing that the chimpanzees are alive and as such deserve to be treated with dignity, since they feel pain, fear, anguish, among other feelings. In addition, it shows that it is logical for human beings to test biomedical advances that will benefit them only.

The speed of sound in air is about 343 meters/second. What is this in mph? (1 mile is approximately 1609 meters.) Round answer to the tenth, one number after the decimal point. Be sure to include the units or your answer will be wrong. Use standard abbreviations for the units. *
Answer:
767.4 miles/hour
Explanation:
To solve this problem, there are two main conversions you need to do. You need to convert from meters to miles and from seconds to hours. To do the conversions, you need to know the conversion factors. In the problem, they give you that 1 mile is equal to 1,609 meters and you likely know that there are 60 seconds in a minute and 60 minutes in an hour. Using this information, we can set up conversion factors that will take us from 343 meters/second to miles/hour. When setting up the problem, you need to make sure that the units that you do not want CANCEL OUT. The units that you want to end up with should not cancel out.
[tex]\frac{343 meters}{1 second}[/tex] × [tex]\frac{1 mile}{1609 meters}[/tex] × [tex]\frac{60 seconds}{1 minute}[/tex] × [tex]\frac{60 minutes }{1 hour}[/tex] = 767.4 miles/hour

Which of the following statements about biodiversity is not true? a)changes to biodiversity never occur naturally b)changes to biodiversity can lead to a decrease in ecosystem stability c)changes to biodiversity can positively and negatively affect on an ecosystem d)changes to biodiversity can lead to an increase in ecosystem stability
Answer:
A
Explanation:
The incorrect statement is changes to biodiversity never occur naturally. The correct option is A.
What is biodiversity?The variety of animals, plants, fungi, and even microscopic species like bacteria that make up our natural world are all examples of biodiversity.
These various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life. The systems that sustain all life on Earth, including humans, depend on biodiversity.
We cannot have the healthy ecosystems that we depend on to give us the air we breathe and the food we consume without a diverse variety of animals, plants, and microorganisms.
There are indications that climate change is having an impact on biodiversity, and pressure is being placed on species that are already in danger due to other human activities by changes in rainfall patterns, harsh weather, and ocean acidification.
Thus, the correct option is A.

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.
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.
