Answer:
Explanation:
Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.
Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.
Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.
Sea otters affected biodiversity because they control the
populations of sea urchins, which endanger kelp forests. Kelp
forests are important because they convert sunlight to living material, and
they also provide food and habitat to sea creatures. Kelp is important in
sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable
for the large size of abalones in California.

Answer:Negative feedback is a type of regulation in biological systems in which the end product of a process in turn reduces the stimulus of that same process.Sometimes referred to as a “negative feedback loop”, negative feedback occurs when the product of a pathway turns the biochemical pathway off.
