a. Photosynthesis produces carbon dioxide, which other plants use to make sugar. b. Photosynthesis absorbs oxygen from the air, which reduces the rate of climate change. c. Autotrophs absorb energy from th Expl
Demand-side response Time-of-use tariffs Economic preferences Environmental attitudes Climate policy support Smart energy technologies 1. Introduction Within the past decade, Germany has witnessed a significant increase in its installed renewable energy production capacity, more than tripling it. Specifically...
How much energy can one atom make?A surprisingly large amount! That was what physicist Albert Einstein meant when he wrote out this simple and now famous equation:E = mc2If E is energy, m is mass (the scientific word for the ordinary stuff around us), and c is the speed of light, ...
The photosynthesis produces glucose, which can be used by the consumers which eat the plants. The organisms at the second trophic level may be consumed by predators from the third trophic level. Only a small percentage of the energy received in the first trophic level form the sun ever ...
Explain how coupling reactions allows a cell to capture the free energy of glucose oxidation rather than allow it to escape to the environment in the form of heat. How does this process affect other reactions in the cell? (a) Describe the major reactions and...
was born that the Universe is filled for the most part not with ordinary matter, but with some “dark energy,” which has special properties. No one knows what is it and how it works, so it named “Dark Energy” as something unknown. And 70% of the Universe consists of this Energy....
a measurement of how much a simple machine multiples a force. The bigger the mechanical advantage, the less force you need, but the greater the distance you have to use that force. The weight rises 1m, but now we have to pull the loose end of the rope twice as far (2m). How come...
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms.
all along. These scenarios are subjected to the same rigorous assessment: a group of researchers leans toward a particular idea, they make observations of the star, analyze the data, compare their proposed scenario against the findings of other researchers worldwide, and see how it all adds up...
The relationship between plant productivity and species richness is one of the most debated and important issues in ecology. Ecologists have found numerous forms of this relationship and its underlying processes. However, theories and proposed drivers ha
