The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />

-Is it possible to give nature and have shelter on other planets?
-What caused the global-warming?
-How can plane's fly?
Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
Answer:
A rare disease that causes damage to the cell's ribosomes will have as a direct effect the inability to perform protein synthesis.
Explanation:
Ribosomes are cellular organelles formed by proteins and a type of RNA called ribosomal RNA, whose function is to translate the genetic code of the mRNA codon sequence and convert it into amino acids. This implies the first step for protein synthesis to occur.
<em><u>If a rare disease could structurally or functionally affect the ribosomes, the translation of mRNA into amino acids could not occur, so protein synthesis in the cell would not be possible</u></em>.
The consequences of the lack of protein synthesis involve severe consequences on the structure and function of a living organism.
Answer:
sensory neurons
Explanation:
Sensory neurons carry nerve impulses from sense organs and internal organs to the central nervous system.
