The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
Answer:
Explanation:
Landscape of of a place includes features and what the environment is made of, it could be a pictorial view.
Ocean landscape gives a view of ocean, its features and environment.
Ocean floor landscape helps to know the huge and long underwater mountain chains that results in earthquake which is due to volcanic activities.
Its helps to view mountains in the ocean floor
Ocean landscape gives a beautiful imaging of nature and it features
It passes across information using the features around the landscape.
Landscape gives information about a place and its an advantage.
They are saying that every theory can eventually be changed a bit due to further research. It does not mean the theory is bad, just that it can become better.
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
