First question is D poor farming practices
The water cycle is a system that shows how the water moves around in different states to transport itself. It uses different states which show a different transportation such as evaporation or condensation. The water cycle can also use continuous movement above and below the earths surface. There are five main steps to the water cycle which are evaporation, condensation, precipitation, transpiration, and runoff but there are still many more.
Hope this helps! :)
Urinal system aka renal system
Answer:
Attached R side groups
Explanation:
The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.
The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.
It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.
Thus, the presence of different R group is the key difference in 20 amino acids.
