<u>Answer</u>:

5 neutrons  are in the isotope lithium-8

<u>Explanation</u>:

In the periodic table, lithium being the third element, its atomic number will be 3. i.e. it has 3 protons.  

The atomic number = proton number

i.e. 3,

again we know that Mass number - proton number = neutron number.

In the given case it is, 8-3=5

In isotope 8 mass number will be 8, so as in isotope 7 it will be 7.

being a 3rd element in the periodic table its K shell contains 2 electron and L shell has 1 electron.

Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.
avanturin [10]
Lets see both procedures:
<span>Mitosis is a process of cell duplication during which one cell gives rise to two genetically identical daughter cells. Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell. Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and mibranes. Meiosis is useful for sexual reproduction of organisms. I hope this can help greatly</span>
