In the atom, which particles are in constant motion around the nucleus?

Biology
1 answer:
scoundrel [369]3 years ago
5 0

Answer:

Electrons

Explanation:

According to the modern atomic theory, atoms are made-up of smaller subatomic particles in the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positively electrical charge and the neutrons have no charge. The electrons have a negative electrical charge and are able to move around the nucleus. An atom usually contains an equal number of positively charged protons and negatively charged electrons. This makes the atom itself electrically neutral. The electrons exist at different energy levels, called shells, around the nucleus where they revolve freely in a constant motion.

Inessa05 [86]

Answer:

The correct answer is cell organelles.

Explanation:

A unique membrane-bound composition, which is found inside the eukaryotic cell's cytoplasm, that is, in plants and animal cells is termed as cell organelle. Some of the examples of cell organelles found within the cells of eukaryotes are endoplasmic reticulum, Golgi complex, mitochondria, chloroplast, etc.  

All these organelles play an essential function for the proper functioning of the cell, like chloroplasts found in plants play an essential role in the process of photosynthesis, and mitochondria both in plants and animals are regarded as the powerhouse of the cell.

What amino acids do trypsin and chymotrypsin cut at?
Vikentia [17]

Answer:

Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.

Explanation:

Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.

Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.

Valentin [98]

Answer:

1) you're going to have to flip the coins (or fake numbers) for the experimental trials.

2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.

When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.

|(100-50)| ÷ 50 = 50÷50 = 1.00

So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.

Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:

|(4-5)| ÷ 5 = 1÷5 = 0.20

So increasing the # flips DECREASES the deviation value!!

Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip
