Answer:
B: volcanic activity
D: fossil fuel consumption
Explanation:
Fossil fuel consumption and volcanic activity are the two factors that has a great influenced on the global temperatures. Fossil fuel consumption is a human activity and volcanic activity both releases carbondioxide gas while burning. This carbondioxide gas is a greenhouse gas which block the reflected solar radiation and leads to increase in the surface temperature of the earth.
Genetic structure, which is inherited by the parents.
A child's eye and hair color are determined by its parents that pass on the genes for red, blonde, brown, black, curly, straight hair, etc, etc.

Answer: B
WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.
