Well, we can rule out diffusion and osmosis because these are passive processes, so we're left with A and C. I'd say A, because the energy is used in muscle contraction.
The truth about blood buffering is that 1). mantains the ph of blood near to 7.4. 2) utilizes the H2CO3/HCO3– conjugate acid/base pair and 3) is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid. Have in mind that the buffer is written as the following: <span>CO2(aq) + H2O(l) <==> H+(aq) + HCO3^-(aq) </span>
The four major organic compunds are lipids, carbohydrates, proteins, and nucleic acids.
Lipids are used to store energy, insulate insulate, and they help build cell membranes. Examples of lipids are fats, oils, and waxes.
Carbohydrates are used to give us quick energy and they help build cell walls. Examples of carbohydrates include bread, pasta, cereal, and rice.
The role of proteins is to build our bodies, help our immune system, and help cells communicate. Such examples include meat, beans, eggs, fish, nuts, soy, and dairy.
Finally, Nucleic acids are used to store gentetic info. Anything plant or animal based is considered a nucleic acid.
Answer:
Researchers initially built up the geologic time scale by considering rock layers and record fossils around the world. With this data, researchers put in Earth's stone layers in request by relative age. Afterward, radioactive dating decided the supreme age of the divisions in the geologic time scale.
