Answer:
Glucose
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
1. It allows the scientist to determine the effect of the changed variable.
Let's say there was an experiment showing the effect of water on plant growth. The environment (in this case, the other variables including the amount of sunlight) would need to be kept under control in order for the results to be clear. If there was a different amount of sunlight during each trial, then the results would be effected by both the water and sunlight, making the results incorrect for the experiment.
The Darwin's theory of evolution states that the organisms evolve through the process of the natural selection of the favorable genetic variations gradually over time. Through this process of the evolution, new species are developed over time. A single population may give rise to different species. These newly evolved species share similarities will each other as they have the same ancestor.
Hence, the given statement is 'true'.
Answer
Hi,
Geochemical cycling is the flow of substances or elements that occurs between reservoirs in Earth’s atmosphere, the water bodies and the lithosphere.
Explanation
A geochemical cycle is normally the path followed by chemical elements in the surface and crust of the Earth. The cycle starts with the crystallization of magma in the lithosphere at the surface or at depth. Weathering and surface alteration follows breaking down igneous rock that will be transported and deposited as sediments. The sediments become lithified and later metamorphosed until melting happens to form new magma.
Best wishes!
