Answer:
Carbon pollution is changing the ocean's chemistry, slowing its ability to uptake CO2, making it more acidic, and harming shellfish and other marine life we depend on. The ocean has absorbed about 29 percent of global CO2 emissions since the end of the preindustrial era.Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.
Answer:
Statement D is not correct.
Explanation:
a. Lobsters are rival but not excludable: This is correct, as lobster is a common resource to which everybody can get access to with no need to pay for it. Besides, a person can consume only one animal.
b. The lobster population is an example of the tragedy of the commons: This is correct, since people, acting by their own needs or interests, may exceed the capture of too many lobsters, affecting their population and, therefore, other users.
c. Reducing the quota on the number of lobsters any fisher can catch would have a protective effect on the lobster population: This is correct, since reducing the number of lobster catches will allow the animal population to reproduce more, leaving offspring capable of reaching sexual maturity, mating and reproducing again, and thus increasing the population size and stabilizing it.
d. If left unregulated, the lobster population will likely <u>increase</u>: This is <u>not correct</u>. There need to be some regulation or management, because if not these animals will continue to be caught, even in the reproductive season, not allowing the population to stabilize. In this case, the population will likely decrease, rather than increase.

<span>The answer is Leukoplakia.
When you have this condition, there is a thickened, white patches that form on
your gums, the interiors of your cheeks, the bottom of your mouth and, occasionally,
your tongue. These patches can't be scratched off. Specialists don't know what the
source of leukoplakia is but consider chronic irritation from tobacco — whether
dipped, smoked, or chewed — to be the main reason in its development. Most
leukoplakia patches are noncancerous meaning that they are benign, though some
show initial signs of cancer. Cancers on the bottom of the mouth can happen
next to areas of leukoplakia. And white areas varied in with red areas
(speckled leukoplakia) may specify the potential for cancer. </span>
