The atomic number of an element gives the element it's identity. This is also known as the number of protons within an element. If you have the number of protons but don't know the element's atomic mass, add the protons and neutrons to get the mass number.
I hope this helped!
Explanation:
when in equilibrium condition the total sum of anti clockwise moment is equal to the sum of clock wise moment
Answer:
The answer is: phospholipid molecules
Explanation:
The plasma membrane of a cell is consists of a lipid bilayer. This lipid bilayer, also known as the phospholipid bilayer, is a polar membrane composed of two layers of lipid molecules, usually amphipathic phospholipid molecules.
The amphipathic phospholipid molecules have a hydrophilic phosphate head on the exterior and a hydrophobic tail consisting of fatty acid chain on the interior of the membrane.

Homeostasis also refers to the process in which an organism maintains balance of things such as body temperature, water levels and salt levels. Many chemical reactions happen in order maintain homeostasis. Hormones must be made by breaking other molecules. ... Muscles need to produce heat in order to warm the body.
Answer:
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
Explanation:
The reaction :
Balancing of reaction in an acidic medium:
Step 1: Balance the atoms in the reaction:
Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;
Step 3: Balance the hydrogen atom by adding hydrogen ions on the side where water is absent:
Step 4: Now balance charge by adding electrons on the side where more positive charge is present
