<h2>Answer:</h2>
<u>The property is that </u><u>water expands when it freezes and oxygen is trapped inside</u>
<h2>Explanation:</h2>
Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. The oxygen is present in water under the ice and this oxygen is used for breathing by the marine and aquatic animals.
Answer:
True
Explanation:
Denaturing is a process in which protein looses its shape. Due to loss of shape (structure), protein also looses its function. This change in shape is due to change in temperature or pH of the protein.
Due to high temperature the shape of active site gets distorted due to which it becomes non functional. Change in active site of enzyme will change shape of the enzyme and make it unfit for the substrate/reaction.
Plants have two systems for the transportation of substances<span> - using two different types of transport tissue. </span>Xylem<span> transports water and solutes from the roots to the leaves, while </span>phloem<span> transports food from the leaves to the rest of the plant.</span>
After the action potential passes through an axon, gated potassium channels open and allows potassium ions to flow out.
