hail
rain
snow
all of the above
Precipitation includes all forms of atmospheric water vapor that falls under gravity, including hail, rain, and snow.
In meteorology, precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. This includes forms such as rain, snow, and hail. So, the answer to your question - Precipitation includes hail, rain, snow, or all of the above - is indeed, all of the above.

Answer:
The correct answer is - This is an example of halo effect.
Explanation:
Halo effect is considered to be a cognitive bias in which we judge a person based on his behavior and character and make an impression in our mind about that person that the person is nice, good or bad.
So it this case students have got a bad impression of Dr. Weldon because she does not accept late assignments, tells students "be on time or don't come to class," and at least two students got no credit on the term paper because they turned it in a day late.
So when evaluation time comes, students tend to give Dr. Weldon far lower marks because of the halo effect.
Answer:
The Halo Effect.
Explanation:
She seems nicer, kids like her better. That's basically what it sums up to.
Hope this helps. :)
2. The DNA fragment has a lower molecular weight.
3. The DNA fragment has a higher positive charge.
4. The DNA fragment has a higher negative charge.
Explanation:
Boom, here are the correct answers:
- 1. The DNA fragment has a higher molecular weight. (heavier molecules move slower through the gel)
- 3. The DNA fragment has a higher positive charge. (more charge = more interaction with the electrical field)
- 4. The DNA fragment has a higher negative charge. (again, more charge = slower movement)
- 2 is FALSE! Lower molecular weight DNA fragments move faster through the gel, so the fragment that traveled less far in the gel actually has a higher molecular weight.
The DNA fragment that traveled less far has a higher molecular weight.
The DNA fragment that traveled less far in the gel has a higher molecular weight. Gel electrophoresis separates DNA fragments based on their size, with larger fragments traveling a shorter distance. Therefore, option 1 is correct.

Ans.
Chlorophyll b is a green colored, accessory photosynthetic pigment that helps in the process of photosynthesis by collecting enegry. It traps solar energy and transfers it to the chlorophyll a.
Chlorophyll b absorbs red and blue light of electromagnetic spectrum, which ranges from 650-680 and 450-480 nano meter. The light primarily absorbed by the chlorophyll b is blue light.
Thus, the correct answer is 'blue light.'
Answer:
Chitin
Explanation:
Chitin is a natural biopolymer that is made of the N-acetylglucosamine, modified glucose.
Chitin is an important polymer mainly for the fungi and the arthropod insects as it is present in the cell wall of the fungi and the exoskeleton of the insects.
The chitin provides a protective function to this organism that the digestive enzymes cannot degrade this chitin but only the symbiotic bacteria can digest eat therefore they are sometimes avoided to be eaten.
Thus, chitin is the correct answer.
Answer:
Option A, most closely related to mammals
Explanation:
Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.
All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other
Hence, option A is correct
