5. Which sample contains the least number of atoms?
A. 2 mol of NaCl
B. 2 mol of NH3
C. 1 mol of CH3COOH
D. 1 mol of H20

A is the correct answer. Why?

Answers

Answer 1
Because every other sample has at least two different elements and each of them contain more than one atom of the named elements. Also, the moles they are measured in make them increase in number too.

Hope this helps!!

Frantz Fanon said this.

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

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.

Laurie is measuring the temperature in her back
yard. At 4 P.M. she measures –8 degrees Celsius.
For the next 2 hours, the temperature decreases by
3 degrees Celsius per hour. What is the temperature
at 6 P.M., in degrees Celsius?

Answers

Answer:

The temperature at 6 P.M. is -14°C

Explanation:

The temperature at 4 P.M. = -8 degrees Celsius

The duration over which the temperature decreases by 3 degrees = 2 hours

The total decrease in temperature = 2 × 3 = -6°C

There the temperature change after 2 hours = -8°C -6°C = -14°C

The time change after 2 hours = 4 P.M. + 2 hours = 6 P.M.

Therefore, the temperature time after 2 hours = 6 P.M.

Which gives;

The temperature at 6 P.M. = -14°C.

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

Answers

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.

Write a paragraph of at least 250 words analyzing the rhetorical strategies Goodall uses to develop her argument.

Answers

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.
