Answer:
Cold weather triggers the underfur to grow each winter.
Explanation:
this is because they would freeze in the cold water in the winter.
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.
The correct answer for both blanks is "Sodium".
Sodium ions are necessary in small quantities for some sorts of flora, but sodium as a nutrient is extra usually wanted in large quantities by using animals, due to their use of it for era of nerve impulses and for upkeep of electrolyte balance and fluid stability. In animals, sodium ions are vital for the aforementioned capabilities and for coronary heart hobby and sure metabolic functions.
The answer to this question is b
