Phoebe knit a hat for a friend. She started with 197 meters of yarn. When she finished, she had 8,200 centimeters of yarn left over. How much yarn did Phoebe use to knit the hat?
Answer: 115 meters
Explanation:
From the question, we are informed that Phoebe knit a hat for a friend and that she started with 197 meters of yarn but when she finished, she had 8,200 centimeters of yarn left over.
First, we have to understand that 100 centimeters equals 1 metre. Therefore, 8200 centimeters of yarn is the same as 8200/100 = 82 meters of yarn.
The yarn that Phoebe use to knit the hat will be:
= 197 meters - 82 meters
= 115 meters
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.
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.

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.

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?
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.
