<span>For the purposes of this discussion, it is important to note that elements are the basic components of Chemistry. Elements contain atoms. All substances are made up of elements. Compounds are elements that contain more than one type of atom that bond together via a chemical reaction. Mixtures are made up of more than one substance, element or compound that are not chemically bonded together. Compounds and mixtures impact our daily lives because everything we have is made up of elements. An example of a mixture is strawberry ice cream. Milk, cream, and other elements are mixed together to make the ice cream. An example of a compound is water. A droplet of water is made from two hydrogen molecules (elements) and one oxygen molecule.

Which of these is a density-independent factor?
Rufina [12.5K]

Answer:

ExplanatThe geometric or exponential growth of all populations is eventually curtailed by food availability, competition for other resources, predation, disease, or some other ecological factor. If growth is limited by resources such as food, the exponential growth of the population begins to slow as competition for those resources increases. The growth of the population eventually slows nearly to zero as the population reaches the carrying capacity (K) for the environment. The result is an S-shaped curve of population growth known as the logistic curve. It is determined by the equation As stated above, populations rarely grow smoothly up to the …(100 of 4579 words)

In photosynthesis, redox reactions ultimately transfer electrons from ______ to ______.
german

The correct answer is: D) H2O… CO2

Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).

Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.  

The first step: Oxygen in water is oxidized (light energy required)

The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
