Answer:
Atoms are made up of particles called protons, neutrons, and electrons, which are ... Within the main group elements ( Groups 1-2, 13-18), there are some general ... (via loss of electrons), the ion is positively charged and is called a cation.

Answer:
1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases
2) To hold the genetic info for the cell
3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus
4) To bring amino acids to the ribosomes to help build a protein
5) A chain of amino acids held together by peptide bonds
6) Ribosomes
7) Because those are the bases that are complementary in DNA so they must be equal
8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made
9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
 
        
             
        
        
        
In a membrane, the tail of the phospholipids in one monolayer face the tail of the phospholipids in the other monolayer.

What is cell membrane?</h3>
- The cell membrane is a biological membrane that separates and protects the inside of all cells from the outside environment. 
- It is also known as the plasma membrane (PM), cytoplasmic membrane or plasmalemma (extracellular space). 
- The cell membrane consists of a lipid bilayer, which is made up of two layers of phospholipids interwoven with cholesterol (a lipid component) to maintain  proper membrane fluidity  at different temperatures. 
- Furthermore, membranes are composed of membrane proteins, such as those that cannot be separated across the membrane and function as membrane transporters, and peripheral proteins that simply attach to the  outer membrane of the cell and function as membrane transporters. enzymes to help the cell interact with its environment. 
- The integrated glycolipids of the outer lipid layer perform a similar function.
