TRANSDUCTION. This refers to the stimulus being converted into an action potential which is then transmitted in the axons going to the central nervous system. This usually starts at the receptor cell. The stimulus change the electrical potential across the cell membrane. This will result in depolarization of the membrane which allow the action potential to be transmitted towards the brain where the electrical impulse is integrated. This usually happens in sensory cells in the body such as vestibular apparatus, olfactory cells, the retina and even the nerve endings alls over our body.
Answer:
The process illustrated in the diagram is the non light dependent reactions of photosynthesis termed as Calvin Cycle.
Explanation:
- Two molecules of 3-phosphoglycerate (3-PGA) are produced or released from step one to step two of Calvin cycle.
- The source of energy that helps to start step one are ATP and NADPH, mainly derived from the light dependent reaction.
- The oxygen molecule thus formed by splitting of water is release to the nature as oxygen, which living organisms utilizes in respiration.
- Carbon dioxide comes from the atmosphere to start the process.
- Light reactions occurs in the thylakoid membranes of the plant organelles namely chloroplasts.
- Non-light dependent reaction or Calvin cycle takes place in the stroma chloroplasts.

Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
