Answer:
The correct answer will be option-D
Explanation:
The aerotaxis movement experiment performed by the Theodor W. Engelmann played an important role in understanding the photosynthesis.
The experiment was performed on the <em>Spirogyra </em>filamentous algae which were exposed to a different wavelength of light.
The other aerobic bacteria present in the test tubes started moving and accumulated near the two regions of the <em>Spirogyra</em> where they were exposed to the blue and red light of the VIBGYOR.
The region receiving red and blue light produced more oxygen through photosynthesis which indicated that these two wavelengths of the light are more active for photosynthesis than any other wavelengths.
Thus, option-D is the correct answer.
Answer:
The correct answer will be-gas absent in primordial atmosphere (oxygen).
Explanation:
The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.
Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.
Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.
Answer:
- an increase in supply
Explanation:
The interaction between the quantity demanded and the quantity supplied determines the price and the equilibrium quantity in a market economy. This is due to the rationality criteria of the economic agents (consumers will buy more quantities at the lowest possible price) and the law of supply and demand, according to which the excess / lack of products causes price decrease / increase and also an increase / decrease in quantity demanded. Thus, in order for the equilibrium price to decrease and the equilibrium quantity to increase, there must be an increase in supply, as there will be more products on the market, which will cause the price to fall. After the price drops, consumers will demand more. In this way, new price and quantity balance parameters will be determined.
