Answer:
anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen
Explanation:
Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
Answer:
The main function is protection, breathing and support.
Explanation:
An exoskeleton covers the entire surface of arthropod animals, such as arachnids, insects, crustaceans, etc. Its main function is the protection, breathing and support of the muscular system, favoring its fossilization.
All planets have these same layers (From deepest to shallowest, inner core then the outer core, then the mantle, and lastly the crust. A good example is the Earth) that is shown in the diagram, even the sun has all the layers I just listed.
But, some planets I can think of are Mars, Venus, Moon, and the Earth of course.
Layer C. sounds like it could also represent Layer D, since they are so close.
P. S. I did my best to try to answer this.
Eutrophication is the input of excessive nutrients into fresh surface waters. Nutrients can cause algal blooms. Some of these algae can be toxic, and algal death can also result in anoxic conditions, leading to fish deaths. Some indicators of eutrophic conditions can be high measures of important nutrients such as phosphates and nitrates. Another indication of eutrophication can be high concentrations of algal cells. Finally, low dissolved oxygen can indicate eutrophic conditions.
