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
The definition of transformation in bacteria is described by the first statement: transformation is the assimilation of external dna into the bacterial cell. In a more elaborate sense, transformation is described by the altering of the cell as a result of the uptake or intentional incorporation of dna from an external source. It is one of the three processes for horizontal gene transfer. The other two are transduction (infection of a phage), and conjugation (transfer of dna between two bacterial cells that are directly in contact).
Answer:
hmm..unethical i would say..
Explanation:
Hi this would be called lethargy and stupor.
Hope this helps you.
Answer: C) density-dependent inhibition
Explanation: When density is high. cell division is inhibited. Density-dependent inhibition occurs when cells grow to a limit and the density of the area is high, growth becomes inhibited as a result of competition for nutrients, space and growth factors. When such arises, the cells get a notification to stop division.
