through which pathway are most water and solutes reabsorbed in the kidney tubule?
Answer:
proximal tubuleThe majority of water reabsorption that occurs in the nephron is facilitated by the AQPs. Most of the fluid that is filtered at the glomerulus is then reabsorbed in the proximal tubule and the descending limb of the loop of Henle.
Explanation:
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. It can be further classified into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST).

What roles do electrons and hydrogen ions play in the
light-dependent reactions of photosynthesis?
Answer:
Water is broken down into hydrogen ions, electrons, and oxygen gas. Electrons used for energy in photosynthesis but not for general cell needs. Electron energy is then used to make molecules that act as energy carriers.
By enabling the auto keyframe tool, any changes you make to the position, rotation, or scale of an object will be saved on the active frame.
Answer:
True
Explanation: is correct
how do plants and snails affect the CO2 and O2 gases in an aquatic environment
Answer:
Water plants will absorb carbon dioxide for photosynthesis, and some plants will also absorb ammonia (as a source of nitrogen for growth). Aquatic animals like fish and snails absorb oxygen and release carbon dioxide directly into water through specialized structures like gills.

Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
