Alexxandr [17]

To identify the molecule that accepts CO_{2}, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO_{2} or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The CO_{2} acceptor concentration would increase when the CO_{2} is cut off, but decrease when the light is cut off.

The correct option is d.

The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.

Calvin and Benson disrupted the carbon-fixation cycle by either removing CO_{2} or removing light from cultures of photosynthetic algae in order to find the molecule that takes CO_{2}. Following the alteration, they evaluated the concentrations of several metabolites.

Which of the following statements is correct regarding the evolution of flight?
xxTIMURxx [149]

Answer:

d.The wing-assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes.

Explanation:

Two theories were given to explain the origin of avian flight. The top-down theory suggested that the birds' ancestors were tree dwelling species. They took help of wings to glide from tree to tree in order to avoid predator or catch prey. The bottom up theory suggested that the birds' ancestors were ground dwelling species. They took help of wings to maintain a balance and provide a lift for efficient running.

Wing-assisted incline running was a mixture of both the above theories and gave a balanced view point. According to it, birds' ancestors used wings to maintain a balance while running up inclined slopes. The wings helped them to save energy while scaling slopes and eventually a flight mechanism was also developed.

jok3333 [9.3K]

Answer:

The correct answer is "a hypertonic solution".

Explanation:

Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
