Hi there!
Photosynthesis involves carbon dioxide (CO2) and water (H2O) as the reactants with glucose (C6H12O6) and oxygen (O2) as the products. We can write a basic chemical equation:
The equation has to be balanced, so the final equation for photosynthesis would be:
The chemicals in correct order are:
Ans.
The process by which plants, humans, and flatworms get energy for their cellular activities is known as cellular respiration.
It involves breakdown of complex organic compounds, such as glucose, in the presence of oxygen to produce energy in the form of ATP molecules. During the process, carbon dioxide and water are released as byproducts.
Thus, the correct answer is option). 'they all use cellular respiration to obtain energy.'
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.
