The correct answer should be A. spores

Ferns don't have seeds and they reproduce using spores. Cones have seeds in them and seeds fall out. Pollen enters a flower and then the flower becomes a fruit. This is sexual reproduction of plants. Since ferns don't have this, they have to reproduce with spores.

Approximately 40% of the energy stored in sugar molecules is converted into energy. What happens to the remaining 60%?
Vaselesa [24]
<h3>Answer</h3>

Approximately 40% of the energy stored in sugar molecules is converted into energy and the remaining 60% is wasted as heat energy.

<h3>Explanation</h3>

Cellular respiration is the process which take place inside a living organism by which organic compounds, usually carbohydrates, are broken down releasing energy that is used to produce ATP molecules that supplies energy/power to cells.

<h3>Example of respiration</h3>

C6H12O6 + 6O2 —– enzymes & coenzymes ——> 6CO2 + 6H2O + Release of Energy (≤38 ATP) + Heat

So, 40% of the available energy of glucose is release as ATP and the remaining 60% is lost as heat and helps to generate your relatively high body temperature.
