The primary mechanism for converting atmospheric carbon into usable forms for life on earth is achieved by photonsynthesis. It is a process where plants convert carbon dioxide into forms that can be used by living organisms which is oxygen. Oxygen is a very essential product of photosynthesis which is being used by living organisms to survive.
Answer:
a. Interference patterns are observed when a wave passes through a barrier with two slits
Explanation:
Interference is a situation where two waves superimpose to form a new wave of a different amplitude. This amplitude can be greater, same or lower.
the diagram attached below shows the movement of a wave through a barrier with two slits.
you can notice the portions of the wave that overlap. This overlapping of waves is the interference.
Thus, option A is correct.
The other options however, are not correct. as shown below:
Option B is wrong as waves exhibit diffraction <em>(it is diffraction of the light wave that produces the rainbows we see in the sky)</em>
Option C is wrong as waves do not travel straight through slits always.
Option D is wrong as waves can also interfere constructively and destructively.
The last intermediate in citric acid cycle is Oxaloacetic acid.
<h3>What is Citric Acid Cycle?</h3>
Organic molecule HOC(CO2H)(CH2CO2H)2 is the chemical formula for citric acid. It is a weak organic acid that is colorless. Citrus fruits naturally contain it. It is a biochemical intermediary in the citric acid cycle, which is a component of all aerobic organisms' metabolism.
Every year, more than two million tons of citric acid are produced. It is frequently used as a flavoring, an acidifier, and a chelating agent.
Citrates, which include salts, esters, and the polyatomic anion present in solution, are derivatives of citric acid. Trisodium citrate is an example of the former; triethyl citrate is an example of an ester.
