Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
               <em>              C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂ + ATP ↑</em>
<em>                Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions: 
- <em>oxygen + water </em><em>→</em><em> glucose + lactose
</em>
- <em>glucose + lactose </em><em>→</em><em> oxygen + water
</em>
- <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>
<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>
 
        
             
        
        
        
Answer:
Digestive
Explanation:
The by-products of digestion are solid waste which is removed through egestion. 
 
        
             
        
        
        
<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
 
        
             
        
        
        
The answer is a. accessible population because an accessible population is the portion of the target population to which the researcher has reasonable access.
        
             
        
        
        
It means they constantly interact with each other and with their environment and are dependent upon each other for survival.
Hope this helps you out :)
