Even though rodents known as sugar gliders and flying squirrels are members of distinctly different groups of organisms and live
EleoNora [17]

Answer:

convergent evolution.

Explanation:

When organisms of distantly related species or groups are found in similar environmental conditions, they develop some similar features which are otherwise not present in their ancestral species. This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.

slamgirl [31]

Answer:

b. become part of the body's structural systems.

Explanation:

  • Minerals are the inorganic regulators needed for different functions inside the body.
  • Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
  • They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
  • Maintaining bod fluid balance.
  • For structural units.
  • Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
  • They become the part of the body's strctral systems (Hence option B is the right answer)

SUNLIGHT
Mazyrski [523]

Answer:

"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.

"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.

These statements are true, however:

SUNLIGHT

CARBON DIOXIDE

WATER

MINERALS

OXYGEN

PLANT SUGARS

Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.

Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
