The chemical reaction for photosynthesis is 6CO2+ 12H2O+ Light Energy -> C6H12O6 + 6O2 + 6H2O. If the input water is labeled with a radioactive isotope of oxygen, 18 O. then the oxygen gas released as the reaction proceeds is also labeled with 18 O. Which of the following is the most likely explanation?

Ectocarpene is a volatile, sperm cell-attracting material released by the eggs of the seaweed ectocarpus siliculosus. its constitution is all the double bonds are cis, and the absolute configuration of the chirality center is s. draw a stereochemically accurate representation of ectocarpene.

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?

The distribution of related animals and plants across the world
