Action and absorption spectrum of photosynthesis overlap.'Explain.

What do we learn from the story of Jadav Molai Peyang?

In the figure given below, the black line (upper) indicates action spectrum for photosynthesis and the lighter line (lower) indicates the absorption spectrum of chlorophyll a, answer the followings: If chlorophyll-a is responsible for light reaction of photosynthesis, why do the action spectrum and absorption spectrum not overlap?

In the figure given below, the black line (upper) indicates action spectrum for photosynthesis and the lighter line (lower) indicates the absorption spectrum of chlorophyll a, answer the followings: How can we derive an absorption spectrum for any susbtance?

What do we learn from identification of individuals and population?

Which sources do we get heat from ?

Which of the following can be concluded from the given graph plotted for four wires of same material and same thickness.

Read the following statements and find out the incorrect statement. A. Ultimately all the food that is respired for life processes comes from photosynthesis. B. The energy released by oxidation in respiration is directly used for the life processes. C The carbon skeleton produced during respiration is used as precursors for biosynthesis of other molecules in cell. D. Plants, unlike animals, have no specialised organs for gaseous exchange but they have stomata and lenticels for this purpose. E. During oxidation within a cell, all the energy contained in, respiratory substrates is released free into the cell in a single step, which is trapped as chemical energy in the form of ATP.

On investigation of light from three different stars A, B and C, it was found that in the spectrum of A, the intensity of red colour is maximum, in B the intensity of blue colour is maximum and in C the intensity of yellow colour is maximum. From these observations, it can be concluded that

Answer the following questions: Take a large shining metal spoon. Bring the deeper(i.e., concave) surface closer to your face. Can you see your image? Now take the spoon away from your face. What change do you observe in the image? Now repeat the activity by turning the convex surface of the spoon to the front. What changes do you notice in the image?
