Answer:
Wingless offspring
Explanation:
Complementation is the terminology used for finding difference in the mutation of same or different gene.
Two groups with same complementation have failed to complement each other.
Thus, two wingless flies will have the same genotype i.e “ww”
When two wingless flies are crossed following offspring are produced
ww * ww
ww, ww, ww, ww
All the offspring are wingless too
More enzymes more useful collisions
Most likely A from my point of view
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy. The remaining heat on the surface is sent out into space in the form of infrared radiation.
