Answer:
B)hydronium
Explanation:
This chemical structure is formed when an acid is disolved into water, as the cation (H+), which comes from the acid, cannot exist as such isolated in water (H20), hence the proton (H+) will be hydrated by a water molecule (H2O)
The union between H+ and H2O is due to the pair of electrons from oxygen and positive charge from H+
Answer:
b. carbon dioxide
Explanation:
This metabolic pathway is called the Krebs cycle after the scientist who first discovered it in 1937. The Krebs cycle is further broken down by pyruvic acid, obtained in the glycolysis process. The process proceeds in two stages. The first is the degree of decomposition of the bicarbonate residue.
The Krebs cycle is the main metabolic pathway for the breakdown of organic matter and the production of energy in the form of reduced coenzymes, which will then be incorporated into ATP.
Answer:
Letter B.
Explanation:
Aquaporins, also known as "water channels," are the main transport of water through the membranes of plant, animal, and bacterial cells. These channels allow the water to travel into and within cells and, at the same time, exclude the passage of ions and solutes.
What makes letter B the correct answer, is the form of transport and shape of the channel that allow water according to the osmotic gradient. In this model, letter A shows simple diffusion, while C and D seem to illustrate gated channels.
Answer: C
Explanation: The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.
