Answer: High Specific Heat Of Water
Explanation:
Water’s high specific heat helps to maintain low temperature and protects fish life. This is due to the presence of hydrogen bonds in larger amount between water molecules. Of course, specific heat plays a role to capture more energy without rise in temperature.
When heat gets absorbed, water molecules move freely and hydrogen bond gets broken. If temperature decreases, release energy by forming hydrogen bond. Hence, it clearly shows that this water property can drastically change the temperature quickly which is important in protecting a fish in a shallow pond on a hot summer day.
11 is b but I don’t know the rest sorry
State 1 is liquid cause liquids dont have a fixed shape and are free to take the shape of the container that it is in. State 2 is a solid because solids have a fixed shape and arent able to take the shape of the container
Answer:
B.
Explanation:
The movement of substances(ions and molecules) against their concentration gradient is called Active transport.Since these substances are moving against whew they are already in abundance,extra energy is needed for them to move against this gradient.Therefore,ATP.,oxygen is needed by the cells undergoing this transport process to transfer substances into the cells.
It is useful for entry of substances in plants e.g glucose,and for transport of materials in intestine in man
Na-K pumps, exocytosis,endocytosis are examples of this transport process.
It is inhibited by lack of oxygen,cyanide etc.
