Sarah is testing how quickly saltwater freezes. She adds saltwater to one ice tray and plain water to another ice tray. She places each tray in the freezer and records the time when each one starts to freeze. What treament did she do?. . A.Salt. B.Water. C.Freezer. D.Ice tray

Answers

Answer 1

Answer: The correct answer is A. Salt

That is because all of the conditions and the ingredients are the same. The one thing that makes the difference is the salt, which if removed, would cause everything to be the same. If she knows at how much regular water freezes, she can easily see how salt impacted the difference.

Answer 2

Answer:

Can you provide an example for both fission and fusion

Answers

fission energy is gained by splitting apart heavy atoms fusion is combining light atoms

Nuclear fusion differs from nuclear fission because nuclear fusion reactions(1) form heavier isotopes from lighter isotopes
(2) form lighter isotopes from heavier isotopes
(3) convert mass to energy
(4) convert energy to mass

Answers

Nuclear fusion is the forceful collision of two nuclei to make a larger one
So the answer is (1)
(2) Would be nuclear fission
For (3) and (4), you can't convert energy from anything that isn't another form of energy, and you can't convert it in to anything that isn't another from of energy

Nuclear fusion differs from nuclear fission because nuclear fusion reactions. Nuclear fusion forms heavier isotopes from lighter isotopes. Nuclear fission forms lighter isotopes from heavier isotopes. therefore, the correct options are option 1,2.

Nuclear fission gets a nuclear process in which the atom's nucleus is divided into smaller nuclei by being blasted with low-energy neutrons. In this process, a large quantity of energy is released. Nuclear fission processes are employed for nuclear power reactors due to their simplicity and high energy output. When multiple atoms unite to produce one heavier nucleus, the process is known as nuclear fusion. In comparison to the energy produced throughout the nuclear fission reaction, a tremendous quantity of energy is released during this process.

Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?

Answers

To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.

True or False: Plants don't have brains, but they still adapt to their environments.

Answers

True, Plants don't have brains, but they still adapt to their environments.

What is adaptation?

Adaptation is a process where they are changing their nature to suit the environment.

We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.

Hence, plants have no brains, but they still adapt.
