The correct answer is: There are 20 primary teeth, and by 24 months of age most children have all 20.
Primary teeth also known as deciduous teeth, milk teeth, are the first set of temporary teeth in the growth development of humans. They develop during the embryonic stage of development, become visible in the mouth during infancy (erupt) and usually get replaced by permanent teeth around age six (the first tooth). The primary teeth consist of 4 central incisors (one in each quadrant), 4 lateral incisors, 4 canines, 4 first molars, and 4 secondary molars.
Is this a bunch of typos or did you put this question in a different language?
Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
The nuclear equation that represents the fusion of two H-2 atoms to form He-3 and one neutron is
In a nuclear reaction the nuclides are represented with the chemical symbol preceded by a superscript that represents the mass number (number of protons plus neutrons) and a subscript that represents the atomic number (number of protons).
<h3>What is a Nuclear reaction ?</h3>
A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Answer:
Mutation
Explanation:
I believe it is a mutation. A mutation is when the DNA is copied with a small mistake. Ex: AGCC => AGGC
Then, after a mutation, the DNA isn’t exactly identical because of this mistake in the DNA after copied.
I hope this helped! Happy Thanksgiving! GOBBLE GOBBLE!
