1. What is the result of a rock undergoing physical weathering?
juin [17]

1. The answer is; soil.  When rock weathers, it disintegrates into small and smaller particles. When these fine rocks particles combine with organic matter from living organisms, they make soil. The mineral component of the soil is therefore similar to that of the parent rock from which it came from.



2. Chemical weathering involves the reaction of the rock mineral with ‘chemicals’ or other compounds. These may include reaction with organic acids or acidic rainwater.  Due to the chemical reaction, the rock chemical composition changes and the physical appearance may also look different.



3. The answer is limestone rocks. They are made of carbon-carbonate minerals. Carbon carbonate is easily dissolved by acids include slightly acidic rainwater/ precipitation.        

CO2 + H2O → H2CO3 (carbon dioxide + water → carbonic acid)

H2CO3 + CaCO3 → Ca(HCO3)2 (carbonic acid + calcium carbonate → calcium bicarbonate)




4. Weathering of rocks is slower in cold regions than dry regions. This is because cold places do not encourage chemical weathering. Chemical weathering requires higher temperatures to  increase the energies of the chemical atoms so that they react fast.

(PLEASE HELP) Describe the difference between mechanical and electromagnetic waves. Give an example of each kind of wave related
Stolb23 [73]
One difference between mechanical and electromagnetic waves is that mechanical waves need a medium to pass through (solid, liquid, gas). EM waves can travel through matter or though a vacuum. In regards to telecommunications, EM waves can be radio waves, these are used in TV's, phones, computers, radios. Mechanical waves somewhat relate to this since radios produce sound;so an EM wave would turn into a mechanical vibration inside a speaker then sound would be produced.

How many nucleotides are needed to code for an amino acid
ivanzaharov [21]

Answer:

Three nucleotide

Explanation:

Three nucleotides are required to code for one amino acid. There are four types of nucleotides A, T, G, C which make DNA. So a doublet of nucleotide code which involves only two nucleotide would be insufficient to code for 20 amino acids because if 4 different nucleotide is taken two at a time then it can only produce 16 amino acid(4²=16).

But if we take three-nucleotide than the number reaches 64 which is more than sufficient to code for 20 different amino acids(4³= 64). Therefore 3 nucleotides are needed to code for an amino acid.
