Answer:
Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.
But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.
Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
Answer:
D. Small population size
Explanation:
Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.
The process of apoptosis, I believe, is when the tadpole's tail is reduced in size during metamorphosis.
In most animal phyla, metamorphosis actually takes place in conjunction with morphological, ecological, and physiological changes.
Marine invertebrates' larva behaves as a drifting tiny creature in the ocean, expanding its habitat distribution to find the best location for its survival.
When muscle cells undergo apoptosis, which is the final stage of their metamorphosis, they are split into membrane-bound muscle fragments and consumed by macrophages.
As a tadpole becomes a frog, apoptosis occurs. The cells in its tail are induced and it will be lost.
