Answer: Xenon
Explanation:
if you look on the periodic table of elements, youll notice that the only element with 54 protons is Xenon. Hope this helps!!
Protons are the positive charged subatomic particle that lies with the neutron in the nucleus of the atom.
The unknown element with 54 protons will be Xenon.
It is because Xenon is the only element in the periodic table having 54 protons. Element has the same number of protons and electrons therefore Xenon is the element that will have 54 protons.
It belongs to the noble gas group because the outer shell is a filled valence shell that is stable and less reactive compared to other elements.
Therefore it will be less reactive compared to the element having 30 protons.
The elements having similar properties as Xenon will be helium, neon, argon etc because they have the same group in the periodic table.

Why is growth and reproduction of a cell cycle?
Answer:
In addition, a larger cell is less efficient in moving nutrients and waste materials across the cell membrane. - Asexual reproduction is the production of genetically identical offspring from a single parent. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.

B enzymes
C fatty acids
D hormones
Answer:
Question 1 :
Ans - C
Explain - Binomial system is made up of Genus (Capital letter) and species (small letter).
# order needs to be correct, Genus
species
Question 2 :
Ans - B
Explain - Meat contain protein where enzymes break down protein into amino acids.
Question 3 :
Ans - B
Explain - Enzyme is a biological catalyst where they speed up chemical reaction.
1. The correct way of naming an organism using the binomial system is Ranunculus acris.
2. When an enzyme is added to meat, amino acids are produced.
3. Enzymes ensures that metabolic reactions take place effectively.
What is binomial system?"Binomial system/nomenclature is the biological system of naming the organisms in which the name is composed of two terms, where, the first term indicates the genus and the second term indicates the species of the organism."The first letter of genus should be in capitals.The species name should be in small letters.What is an enzyme?Enzymes are biological catalyst that increases the rate of metabolic reactions.What are amino acids?"Amino acids are molecules that combine to form proteins."Meat is abundant in protein and when protein digestive enzymes are added it breaks down into its simpler form i.e., amino acids.
Hence the correct answers are: 1. C. Ranunculus acris, 2. B. an enzyme and 3. B. enzymes.
