Environmental selective pressures. In other words, natural selection took place. It was the environment that caused these changes. Birds on the islands with the most suitable traits for survival thrived while the birds that didn't die.
The only cause we know of that could shift the spectrum of a source toward longer wavelengths isthe source moving away from us. That's how we interpret the red shift when we see it, and that's where the whole idea of the expanding universe comes from. But ... just like gravity and the Earth going around the sun ... it can't be proved, so it's "only a theory".
For this problem, we will use the formula setup for Molarity.
The formula is M= moles
---------
liters
So, lets plug in the numbers we have. We know M= 0.954, and L (liters)= 3.63. Lets plug that into our equation.
x
0.954= -----
3.63
As we can see, our moles are unknown.
So, lets multiply 0.954 times 3.63 to get our moles.
0.954 x 3.63 equals 3.46302.
We know this is our correct answer, because when we divide 3.46302 and 3.63, we get 0.954.
Why?
Because when we divide the moles by liters, we get the molarity.
I hope I helped!!!!!
Here are some common units to know if my units confused you.
M= Molarity, which is what we find by dividing moles by liters
mol= Moles
L= Liters
It’s a I think A because they Need light to be a refracting telescope. Making them a refracting telescope
The half-life of a radioactive compound is the time taken for that said isotope to decay or disintegrate so that only half of the initial atoms remain in that compound. During the decay process, the isotope will give off energy and matter, and the way to depict this is indicated by t 1/2.
