Answer: Both formulas identify the specific atoms in a particular compound. However, a structural formula also shows how the atoms in a compound are bonded together.
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Structural formula is the formula which depicts the actual number of atoms of each element present in the compound by showing the bonding between the atoms.
Lewis structures show the valence electrons around each atom present in the compound.
The difference between cytoplasm and cellcytoplasm is jelly like fluid part of the protoplasm
Plants use their stomata to take in Carbon dioxide and take out oxygen during photosynthesis. It's how they "breathe" if that makes it more understandable.
One evolutionary explanation for why lizards living in the same part of the habitat would have similar characteristics is adaptation. It is a function or structure that is very common in lizards and other animals. If the lizards are leaving in a same part of habitat they will have the same characteristics which they will adapt coming from the same habitat.
Answer:
C) The amount of A is always equivalent to T, and C to G
Explanation:
Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A), Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
