According to Charles Darwin, the Theory of Evolution is the process <span>by which organisms change over time as a result of changes in heritable physical or behavioral traits. These changes were brought about to allow organisms to adapt to its environment and survive and produce offspring.

The law of superposition supports the theory because it is a basic law that states that in any undisturbed sequence of rock deposits, the oldest strata is always at the bottom. And as the layer goes up, the younger the age of any discovered fossil is.

The geologic timescale supports the theory because it is a chronological dating system wherein the timing and the relationship of events that occurred in a specific place is described and connected to Earth's history.

Fossils are proofs that there are organisms that lived before us. The conditions where fossils are found are also linked to their conditions at the time they were still alive. Changes in the area can be studied and observed to predict why and how fossils lived and died. </span>

The chemical equation below shows the photosynthesis reaction.

Scorpion4ik [409]

Firstly, you should notice that for each 6moles of CO2 6moles of H2O is to be consumed in parallel for the reaction to occur. So it is 6:6 relation which means 1:1 relation. So whatever number of moles of CO2, the number of moles of H2O consumed should be exactly the same.
The equation to find the number of moles is:
#moles= mass used of the material/ molar mass of the material.
Now look closely, you only have both the used mass and the molar mass of CO2, and using the fact we mentioned before, so using the equation to find #moles of CO2 will give us a number that is exactly equal to the number of moles of H2O.
#moles of CO2= #moles of H2O= mass CO2/ molar mass CO2=
$528 \div 44.01 = 12$
So #moles of H2O= 12mole.

Hope this helps.

Setler79 [48]

Answer:

The dna of every eukaryotic cell is stored in one or morechromosomes located in the nucleus

Explanation:

The nueclear compartment has 46 chromosomes each consisting of a long DNA molecule combined with proteins called histones (chromatin). When certain sectors of DNA are translated to generate RNA, these molecules leave the nucleus to begin protein synthesis.
