Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
Function. There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption ofnutrients in the lumen. There are alsoenzymes (enterocyte digestive enzyme) on the surface for digestion.

<u>N</u><u><em>atural selection acts on existing heritable variation</em></u>
Answer: Option C
<u>Explanation:</u>
Natural selection is a process that occurs in nature as a key to evolution. It also goes hand with the survival of the fittest. Nature always selects the best trait to survive or get accustomed to the surrounding by undergoing modifications.
It acts on the genotype of the existing generation and causes variation in the future generation. So the population over generations get to have acquired the variations in their body, structure so that it is adaptable to the surrounding.
Respuesta: Energía eólica.
Explicación: La energía eólica o las cosas que utilizan energía eólica, como las turbinas eólicas, no liberan emisiones que puedan contaminar el aire o el agua. Por tanto, una fuente de energía no contaminante.
Espero que esto ayude, buena suerte! :)
