Answer:
4
Explanation:
If we have the expression, 3/3/4.
Then this is the same as 3 × 4/3
Which is the same as 12/3
Which is the same as 4
Hence the value of the expression 3/3/4 is 4
Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.
Answer:
Aerobic respiration process produce either 36 ATP or 38 ATP depending on the amount of NADH moles while Anaerobic produces 2 ATP. Aerobic respiration produces 32-34 ATP more
Explanation:
Aerobic respiration has 3 steps which includes; Glycolysis which produces 2ATP; Krebs cycle which produces 2 ATP and Electron Transport Chain which produces 32 - 34 ATP depending on the molecule of NADH introduced into the reaction from the kreb cycle
Answer:
c. switching from beef to soy
Explanation:
Switching from beef to soy shall lead to the curbing of lifestyle diseases such as obesity.
At the same time, soy shall provide the nutrients that were needed by the body and could be obtained from beef.
Beef is much expensive compared to beef, thereby, there shall be experienced low expenditure compared to beef.
Therefore the switching from soy to beef shall be a more sustainable food system.
<span>The most dominant chemolithotrophs in pelagic waters are ammonia-oxidizing archaea. The first step in nitrification is performed by ammonia oxidising microorganisms that convert ammonia into nitrite ions. Science has known about nitrifying bacteria for over a hundred years now thanks to the discovery of S. Winogradsky.</span>
