The answer is D. ...................................................
Flagella and cilia have the exact same structures and functions, and the names merely indicate how many are present on a given cell. When found singly or in a pair, these cell protrusions are called flagella<span>.</span>
"How does carbon enter water?" : Carbon<span> dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the </span>carbon<span> dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the </span>carbon<span> into organic matter.
"How does aquatic plants get carbon" : </span><span>The only difference between photosynthesis in </span>aquatic<span> and land </span>plants<span> is where in their environments they </span>get<span> these nutrients. Land </span>plants get<span> water from the ground through their extensive root system, </span>carbon<span> dioxide from the air through their stomata (tiny holes in a </span>plant's<span> leaves), and energy from the sun.</span>
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.
