Answer:
they are the same
Explanation:
since one mole is 6.022×10^23 atoms, one mole of silver is 6.022×10^23 atoms and one mole of tin is 6.022×10^23 atoms. so one mole of tin has the same number of atoms as one mole of silver
B - energy flow from one tropic level to the next
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
I think this stage is the cytokinesis. It is <span>the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. Hope this helped.</span>
