Answer:
A
Explanation:
photosynthesis converts light energy to chemical energy and not the other way round
product of photosynthesis is oxygen and energy
photosynthesis cannot occur is light energy is not available
Beneath the dermis, and is mainly used for fat storage
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
Catalysts are substances that cause a chemical reaction to occur in a different way than it would otherwise happen without that catalyst – a catalyst could cause a reaction to happen at a faster rate, or at a lower temperature, than would be possible without the catalyst.<span>

Answer:
b) the wing assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes
Explanation:
According to Wing-Assisted Incline Running ( WAIR ), proto-birds developed wings as it assisted in running specially on inclined planes. The forelimbs were modified as wings as they provided balance to birds while running at fast speed on slopes. They also used less energy as compared to just running.
There were two more theories, bottom up and top down. According to bottom up, proto-birds were ground dwellers and wings were used to maintain the posture while running. According to top down, proto-birds were tree dwellers and used wings to hop from branch to branch to evade predators and catch prey.
