<span>Kwang Jeon observed that Amoeba had been attacked by a bacterial infection, and lots of the Amoeba had
died. However, some survived and continued to reproduce. After investigating the remaining
Amoeba and their offspring, he noticed they were very healthy. He thought maybe they were able to
fight off the bacteria, but instead, he found they were still infected with the bacteria but were not
dying. The bacteria were no longer making the Amoeba sick. Then, he killed off the bacteria using
antibiotics and was surprised to see that the Amoeba also died. It seemed the Amoeba and bacteria
had formed a relationship in which they both needed each other to survive. After researching, Jeon
found that the bacteria made a protein that the Amoeba needed to survive. </span>
Answer:
saturated
Explanation:
It is not dense enough to be supersaturated.
Answer:
A
Explanation:
Protons are the ones which give rise to different elements, hence different elements have different chemical properties. Therefore, the two atoms must have different proton numbers.
The relative atomic mass of an atom is determined by the mass of the neutrons and the protons. The mass of the electrons are not included due to their negligible mass (1/1840).
Hence, due to the different proton masses, the masses of the neutrons will also differ to ensure that both atoms have the same relative atomic mass.

Answer:
b. 2-4
Explanation:
Look at the slope of the line, between 0-2 and 4-6 the slope is only 10, but between 2-4 the slope is 20, so that's when the temperature is changing the fastest. In the same time it took for the water to increase by 20 degrees between 0-2 and 4-6, the temperature of the water increased by 40 degrees between 2-4 so that's when the change is the fastest.
