Evaporation: Vaporization that occurs at the surface of a liquid below the liquid's boiling point.
Condensation: The change of state from a gas to a liquid.
Precipitation: Rain, snow, sleet, or hail that falls from clouds to the Earth's surface.
Transpiration: The water evaporates from the leaves of plants and moves into the air.
Crystallization: the formation of highly ordered, solid structures from particles in a solutions.
Downhill flow: If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow
The step that is missing in their methodology is DATA ANALYSIS.
Data analysis is a very important step in scientific investigation. It is the phase of the scientific investigation where the results obtained from the experiment are gathered, examined and analysed in order to obtain necessary information from the data.
Answer:
The correct answer is b RNA polymerase is responsible for unwinding the DNA double helix and for catalyzing the formation of phosphodiester bond between nucleotides.
Explanation:
DNA double helix is unwound by the catalytic activity of helicase or dna B by using the energy derived from the hydrolysis of ATP.
RNA polymerase helps in the polymerization of nucleotides b the formation of phosphodiester linkage present in RNA.
Answer:
In the course of evolution mammals are the animals which are evolved recently as compared to other groups such as fish, amphibians, or reptiles.
In addition, fur or hairs on body, mammary glands, middle ear bone, warm-blood, et cetera are the characteristics of mammals.
These characteristics were evolved during the course of evolution; they were not present in ancestral organisms.
However, tail, gill pouches, et cetera are characteristics of our ancestral groups. Thus, characters can be sometimes observed in mammals.
But mammals characteristics can not be observed in organisms which were evolved before mammals such as fishes, amphibians, reptiles, et cetera.
