Density = mass / volume
D = 550 / 25
D = 22 g/mL
hope this helps!
The hypothesis of this experiment is as follows: IF detergent A is used to wash, THEN the clothes will be cleaner.
HYPOTHESIS:
- Hypothesis is commonly referred to as an educated guess. It is a critical part of the scientific method.

Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
Answer:
Statements 1 and 2 are correct.
Explanation:
The microenvironment around a amino acid residue can impact its pKa value according with the Born effect. If there is a positively charged environment, like in the second option, the pKa value will decrease, just as it happens in the histidine residue. So the correct answers are 1 and 2.
