Answer:
White light is made up of different colors. When white light enters water (like moisture in the air) it is bent (refracted). However the different colors are bent (refracted) by different amounts. So this different amount of bending has the effect of separating the white light into its colors and we see this as a rainbow.
Explanation:
The nociceptor does not relay any information to the brain about stimuli below the threshold. This is because stimuli below the threshold do not generate an action potential and thus the neuron is not actively signalling.
Answer:
The correct answer is a. three ATPs
Explanation:
Pentose phosphate is also known as hexose monophosphate shunt and this pathway is the alternative pathway through which glucose is oxidized.
Pentose phosphate pathways are used to produce many intermediated that contains 4 and 5 carbon sugars which are then used as the precursor for synthesis of amino acids and nucleic acids. It also provides precursors for the synthesis of glucose.
NADPH is also produced in this pathway which is used for the reduction of molecules by providing a source of electrons. No ATP generation takes place during the pentose phosphate pathway.
So all the statements are true except a. three ATPs.
Answer:
Exocytosis of vesicles containing glutamate from the nerve terminal would decrease
Explanation:
Glutamate release is regulated by voltage dependent calcium channels. An increase in intracellular Calcium ion concentration is sufficient and necessary to cause glutamate release from astrocytes. Several experiments are done on this study, when these cells are provided with high amount of calcium ions, the glutamate release from nerve terminals increased.
