<span> There are two main methods of determining the salt content of water: Total Dissolved Salts (or Solids) and Electrical Conductivity. Total Dissolved Salts (TDS) is </span>measured<span> by evaporating a known volume of water to dryness, then weighing the solid residue remaining.</span>
The theory of evolution will be best supported by the evidence showing a species changes over time. Thus, option A.
Basic evidences for proving the theory of evolution are anatomy, Biological morphology, Fossils and direct observations. There have been various theories for the proof of evolution like structural similarities in an embryo formation pointed towards common ancestors. Theory of Natural selection embarked by Charles Darwin to show genetic variations picked by organisms in whole population.
The most authentic theory over evidence for evolution is Paleontological theory which includes study, observation and acquired prove of fossils of various organisms in the forms of Petrified, mold and cast, trace fossils, compression fossils, impression fossils, etc.

Answer:
The Inter-Tropical Convergence Zone (ITCZ)region gets the most direct sunlight at any given period in time. This in turn causes air to be unstable with a drop in pressure and rise of air which cools and condenses into clouds to form precipitation causing the wet season in the tropics.
In this region, the sun is directly or almost overhead as seen during summer periods in the tropics.
Only in areas of the North and South of the ITCZ known as doldrums which at times are parallel to the ITCZ do we have high pressure that aren't conducive to precipitation causing dry season in the tropics.
In the ITCZ zone, we also have the tropical rain forests along the equator with huge amount of all round rain for the year.
Along the equator, on either side of the rain forests we have the dry and wet forests with the savannah to the North of this region and the southern hemisphere to the south of these forests since these forests are seen mostly in the ITCZ than the savannahs.
Rain shadows and ocean cueeebts may at times cause some savannahs to be along the equator and some rain forests -wet and dry forests- to be positioned further form the equator.
