Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.

Answer:
I do not know if I am entirely right, so please tell me if I am wrong.
1. Sulfur Dioxide
2. Condensation of chemicals in the atmosphere
3. Acid Precipitation
4. Acidic Water
Explanation:
Sulfur Dioxide is coming out of the factory. (A).
The chemicals are condensation in the clouds (B).
Its raining acid rain(C)
Acidic Water because rain goes everywhere(D)
It would affect marine life BUT it does not say it affects marine life on the tile.
Fat is less soluble in water compared to phospholipids.
This is because, fat is made up of three molecules of fatty acids which are not polar in nature at all, thus they mixed very poorly with water.
Phospholipids on the other hand has its molecules divided into two distinct regions, the head and the tail region. The head region is hydrophillic and it is polar in nature, that is, it mixes well with water. The tail region is made up of the fatty components and it is hydrophobic.
Because of this difference in structure, phospholipid will dissolve better in water.
