Answer:
1) A chemical reaction is shown.
SnO2 + H2 → Sn + H2O
What is true about this chemical reaction?
B.
It is unbalanced because the mass of the reactants (number of atoms) is greater than the mass of the products (number of atoms).
2) Read the information about an experiment.
Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.
Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?
A.
The steel wool should be burned inside of a sealed jar or other closed system.

Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
