Answer:

Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.

Explanation:

Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.

The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.

The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.

There are 8 valence electrons in its outer shell, thus:

  • Ar is not very reactive, as it does not require electron sharing in atomic bonding.
  • It shows low conductivity, as there are no free electrons

kirill115 [55]
Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.

Which of the following is NOT the result of a mutation in the DNA sequence of an organism?
Mama L [17]

DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.

Explanation:

Mutation is the process

It is caused by certain chemicals called mutagens or by environmental factors.

In mutation the nucleotide get change which eventually changes the protein product.

In  mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.

A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.

In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
