A
Explanation:
if the earth slows down then that will give more time to the sun meaning days/nights will be longer
The proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis
<h3>
What is homeostasis?</h3>
Homeostasis refers to an organism's ability to regulate various physiological processes to keep internal states steady and balanced.
<h3>How does plant perform homeostatis?</h3>
As water leaves the plant tissues into the atmosphere, it takes energy with it in the form of heat.
Much like when we sweat, this allows the plant to cool and maintain homeostasis.
Similarly, the same process allows plants to absorb nutrient like ammonium nitrate.
Thus, the proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis.

Answer:
0.912 mL
Explanation:
3 Na2S(aq) + 2 FeCl3(aq) → Fe2S3(s) + 6 NaCl(aq)
FeCl3 is the limiting reactant.
Number of moles of iron III sulphide produced= 3.75g/87.92 g/mol = 0.043 moles
Hence actual yield of Iron III sulphide = 0.043 moles
Theoretical yield of Iron III sulphide = actual yield ×100%/ %yield
Theoretical yield of iron III sulphide= 0.043 ×100/75 = 0.057 moles of Iron III sulphide
From the reaction equation,
2moles of iron III chloride produced 1 mole of iron III sulphide
x moles of iron III chloride, will produce 0.057 of iron III sulphide
x= 2× 0.057= 0.114 moles of iron III chloride
But
Volume= number of moles/ concentration
Volume= 0.114/0.125
Volume= 0.912 mL
