Answer:
Global warming causes sea-level rise as oceans expand, and makes storm patterns more energetic. Consequently it will affect most of the world's coastlines through inundation and increased erosion.

Answer:
C. NaOH acts as a reactant in the reaction
Explanation:
Because during the saponification process, Na+ replaces the H+ in the fatty acid been used for the saponification process
According to the second order formula:
1/[At] = K t + 1/[Ao]
and when we have the K constant =0.0265 & we have t = 180 min & we have the initial concentration of A = 4.25 so by substitution:
1/[At] = 0.0265 X 180min + 1/4.25
1/[At] = 5
∴[At] = 1/5 = 0.2 m
Answer:
Two methods which help us to conserve water are:
Sprinkler irrigation system: this irrigation has an arrangement of vertical pipes with rotating nozzles on the top. It is more useful in the uneven and sandy land where sufficient water is not available.
Drip irrigation system: this irrigation system has an arrangement of pipes or tubes with very small holes in them to water plants drop by drop just at the base of the root. It is very efficient as water is not wasted at all.
Answer:
Biochemistry.
Explanation:
Biochemistry can be defined as the branch of science that deals with the study of the chemical processes, physio-chemical reactions and various substances that are found in living organisms such as animals, plants, and microorganisms.
Simply stated, biochemistry is a field in science that combines both the elements of biology and chemistry in order to study living organisms.
For example, all living organisms have the ability to engage in respiration in other to breathe in oxygen to stay alive. Thus, biochemistry helps us to understand respiration as a physio-chemical process that converts glucose into a form of energy (Adenosine Triphosphate-ATP) that is beneficial to all living organisms.
Hence, the chemistry of living things and living systems created a new combined field in science known as biochemistry.
