Peter conducted the investigation below to find the energy contained in a peanut. If the burning peanut raised 20 g of water from 18°C to 22°C, how much energy did it contain? Use the equation E = m × c × ΔT to find your answer. Assume that c (the specific heat capacity of water) is 4181 J/kg. Give your answer to two decimal places.
Answer:
334.48
Explanation:
delta T = 4 degrees
m = 20 grams of water
c = 4.181 J / gram
E = 20 * 4.181 * 4
E = 334.48 Joules
Remember to change c to Joules / gram
4181 j / kg * 1 kg / 1000 grams = 4.181 j / gram
Which three of the following choices are examples of commons ?

C. The night sky
DD. A neighbor's swimming pool
E. State parks
Answer:
A, C, and E

Personal computers and a neighbor's swimming pool are not examples of commons as the computers are owned by an individual or an organization, whereas the neighbor's pool is also a private property that cannot be accessed by others.
Thus, the correct answers are clean air, night sky, and state parks.

The statement "The DNA condenses and the nuclear membrane breaks" occurs during prophase.
What is prophase?In the beginning stage of mitosis and meiosis known as prophase there are different level of activity. This is when the DNA becomes more condensed the protective nuclear membrane. The mitotic spindle starts to form.
In prophase the DNA undergoes condensation, while simultaneously the nuclear membrane disintegrates. This enables the formation of the spindle. Allows for the movement of chromosomes, within the cell.
