Answer:
Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Explanation:
Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.
For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.
Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Answer:
The correct answer will be- the free energy change will be +13 kcal/mol.
Explanation:
The free energy change of a chemical reaction is the measure of the spontaneity of the reaction in which the negative value of free energy represents that reaction is exergonic while positive value represents that reaction is endergonic.
In the given question, if the free-energy change is 13 kcal/mol for the hydrolysis of ATP to ADP + Pi which releases energy used by the cells then reversal of the reaction that is the formation of ATP molecules from the ADP and Pi requires energy which will be the same energy required to break the ATP.
This shows that 13kcal/mol energy will be used but with a positive sign as the energy is needed or the reaction is endergonic.
