Bogdan [553]3 years ago

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>

Brrunno [24]
<h2><u>Answer: </u></h2>

<u>Erosion:</u> is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.  A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. Most erosion is performed by liquid water, wind, or ice .  Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.

<u>Public domains:</u>VegetationThe simplest and most natural way toprevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soiland prevents soil erosion. Geotextiles: Using geotextiles is an effective method because it also stabilizes soi .

ANEK [815]

Answer:

Cell membrane of prokaryotes and Inner mitochondria of eukaryotes

Explanation:

Electron transport chain is a part of oxidative phosphorylation which is the third step of aerobic cellular respiration in living organisms. The ETC is a complex of proteins and mobile electron carriers. It occurs when electron is being transferred from one electron carrier to another, starting from NADH and FADH2. A proton pump which is used to synthesize ATP is generated at the end.

This ETC process occurs in the cell membrane of prokaryotic cells due to the fact that they lack a membrane-bound Mitochondrion. ETC occurs in the inner membrane of the mitochondria called CRISTAE in eukaryotic cells.

Answer:

C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. ... PEP fixes carbon dioxide into a four-carbon molecule, called malate, that is transported to the deeper bundle sheath cells that contain Rubisco.
