[incomplete
question – see attachment for complete data]
<span>First
option:
Correct. We can make a plot with that data and, if the hypothesis is correct, we
will see that the heat tolerance will increase as the distance decreases.</span>
Second
option:
Incorrect. That’s
not useful until we know the relation between the feeding activity and the heat
tolerance, which would require us to do another experiment.
Third
option:
Incorrect.
It has to be the same species because, if not, we wouldn’t know if the
difference is due to the species instead of the city.
Fourth
option:
Correct. We
will compare the results in one group with the results in the other group and
see if there are meaningful differences.
Fifth
option:
Incorrect. 5
ants is too small to work as a meaningful sample.
Sixth
option:
Incorrect. Being
in the north or in the south has nothing to do with being inside the city or outside
the city. There are large cities and rural areas in both.
Answer:C
Explanation:Heat causes the liquid and frozen water to evaporate to turn into water vapor(gas), witch will then form clouds that will then rain or snow thus repeating the cycle again.
Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
The proton is connected to the atomic number of elements. Protons and neutrons make up the nucleus of the atom while electrons are found around the nucleus
