Question

1 multiple choice 2 points the hydrosphere covers approximately what percentage of earths lithosphere? 100% 70% 50% 25% 2 multiple choice 2 points which of the following processes allows the cells of an organism to use carbon from the environment? mitosis fertilization transpiration photosynthesis

Explanation:

1. The hydrosphere (water bodies) covers about 70% of Earth's lithosphere (solid outer part).
2. Photosynthesis is the process where plants (and some other organisms) take in carbon dioxide (\(CO_2\)) from the environment and convert it into organic compounds (using carbon) with the help of sunlight. Mitosis is cell - division, fertilization is the fusion of gametes, and transpiration is water loss from plants.

Answer:

1. B. 70%
2. D. photosynthesis
