Answer:

Hydrogen.

Explanation:

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.

Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.

However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.

<em>Hence, Hydrogen is an element which does not want to have eight valence electrons. </em>

Explanation:

  • Protein is the building block of our body. It forms the body tissue and even acts as a fuel source.
  • But protein found in antibodies are slightly different in their function. In antibodies, protein develops the immunity power that shields our body from the external antigens that may cause dysfunction in our body.
  • These antibodies drags out any antigens attacking our body systems.

Bezzdna [24]

Answer:

Generation of ATP in muscle cells.

Explanation:

Mitochonria is the power house of the cells, in this organelle of cell the biochemical process of respiration and generation of energy occurs. Energy produces in the form of ATP.

Mitochonrial DNA coded for specific protein complexes which are responsible for the process of electron transport chain and ATP synthase. If in the mitochondrial genes mutation occurs it will affect the production of ATP (energy) in muscle cells.
