Answer:
Having a true coelom as a body cavity.
Explanation:
Coelomate contain tissues derived from mesoderm, whereas pseudocoelomates have no such tissue. have a gut that lacks suspension within the body cavity, whereas pseudocoelomates have mesenteries that hold the digestive system in place. Have a body cavity completely lined by mesodermal tissue, whereas pseudocoelomates do not.
Answer:
C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.
Explanation:
The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.
Why not the other answers:
A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.
The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.
B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.
D) Wading birds were never eaten by ospreys. There is no arrow connecting them.
Answer:
Passes absorbed energy to chlorophyll A.
Explanation:
Chlorophyll is a pigment found on the chloroplasts, it absorbs and reflects light's fotons in order to fuel the photosynthesis process where plants convert light into energy. There are two types of chlorophill:
- <em>Chlorophyll A:</em> a blue/green substance that is always necessary for photosyntesys, it absorbs light from red to blue areas and it acts as a primary electron donor in the electron transport chain.
- <em>Chlorophyll B: </em>a yellow/green substance that absorbs only blue light, it serves as an extension for the plant to absorb a broader range of light. <em>The extra energy absorbed by this clorophyll is then tranfered to chlorophyll A</em>.
