It has not. Evolution is not a process that can happen to individual organisms; it's change that happens to a species over many generations.
Amino acids are the monomers that make up proteins. Amino acids are made of a carboxyl group (Carbon, Oxygen, Hydrogen), an amino group (Nitrogen and two Hydrogen), and finally an R group which differs in each amino acid. That R group is what makes each amino acid different! They can also act as enzymes. Essentially enzymes act as biological catalysts and control the functions of the cell and build cells.
Answer:
The correct answer is A. 3O₂ + 2Al → 2AlO₃
Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.
For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.
Mass of oxygen = 16 x 3 = 48 AMU
Mass of aluminium = 2 x 27 = 54 AMU
Total molecular mass of the reactants = 102 AMU
Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.
Hence, the total mass of the matter remains the same.
Answer:
Ginkgos and Cycads
Explanation:
Gymnosperm plants such as Ginkgos and Cycads have flagellated sperm.
<span>The statement is a hypothesis rather than a theory because it depends on the volume of the rainfall on sand dunes increases, therefore, there will be a result or conclusion that the erosion of the sand dunes will also increase.</span>
