Question

a student correctly states that waters ability to act as a universal solvent is crucial for life. which of the following is an example of this propertys importance in a living organism? hint: what does it mean to be the universal solvent? a plants ability to absorb water through its roots. the transport of glucose and oxygen in the bloodstream. a beetle being able to walk on the surface of a pond. the regulation of body temperature through sweating. a cell is lacking in its ability to store energy for long - term use. this cellular dysfunction is most likely related to a deficiency in which type of biomolecule? hint: what is used for long term storage? carbohydrates. nucleic acids. lipids. proteins.

Explanation:

1. Water as a universal solvent means it can dissolve many substances. Glucose and oxygen dissolve in water - based blood plasma for transport in the bloodstream, showing water's solvent property. Absorbing water through roots is about uptake, not solubility; a beetle walking on water is due to surface - tension; sweating for temperature regulation is about water's high heat of vaporization.
2. Lipids, especially fats, are used for long - term energy storage in cells. Carbohydrates are for short - term energy, nucleic acids store genetic information, and proteins have various functions like structure and catalysis but not long - term energy storage.

Answer:

1. B. The transport of glucose and oxygen in the bloodstream
2. C. Lipids
