Answer:
Phosphorus cycles between living things and the soil.
Plants absorb phosphates from the soil and turn them into organic compounds through assimilation.
Animals eat plants and pass the phosphorus through the food chain from one animal to the other.
An animal dies and decomposes, returning the phosphorus to the soil.

Answer:
Molecular arrangement is the property of water remains unchanged when it recycles in the atmosphere
.
Explanation:
In the water, Molecular arrangement remains same when it recycles in the atmosphere
. A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent.
This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. Thus it is the element or property which remains in same condition.
ecosystem, Biome, biosphere, idk where habitat goes sorry
Answer: in order for a scientific investigation to be valid A hypothesis must be tested throughout a Scientific investigation that can gather evidence and support it.
Explanation: in any scientific investigation you have to have a testable hypothesis, without your hypothesis it’s not really a scientific investigation.
Hope this helped!
Answer:
Option (4).
Explanation:
Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.
The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.
Thus, the correct answer is option (4).
