<h2>Answer:</h2>
The pH of the pond water and survival rate of animal species living in the pond has a direct relationship with each other. Animal species can survive at a specific level of pH"Optimum pH" at which these species can show their maximum activity. 
If we decrease the pH the pond water will become more acidic and it will become challenging for species to survive in the acidic environment and if we increase the pH the water becomes more alkaline and again it affects the marine life. So, the pH of pond water should be in normal ranges.
 
        
        
        
Answer:
The answer is D.
Explanation:
According to the information given in the example, Zack is most likely to have suffered damage to his brain's frontal lobe becasue of the symptoms that he show such as a change of personality. Frontal lobe is located at the front of the brain and it is responsible for controlling functions such as judgements, decision making, personality traits, emotions and memory which are all among the most important things for someone to function properly. So the correct answer is D.
I hope this answer helps.

Answer:
The basic processes of cellular respiration are: glycolysis, followed by Krebs cycle, the electron transport chain and chemiosmosis.
Explanation:
This task asks one to arrange the basic processes of cellular respiration in the correct order.
Place the major steps of cellular respiration in order by dragging the appropriate figure to each box.
Cellular Activity 1. Glycolysis pathway- The reaction starts with glucose. In the process, glucose is oxidized and split into two 3-carbon compounds. The byproducts is 2 ATP, 2 NADH, and 2 molecules ofpyruvate.
Cellular Activity 2. Krebs cycle- The Krebs cycle follows glycolysis, its an aerobic process but before the glycolysis end-product enters the Krebs cycle, it must first undergo loss of CO2, oxidation, and attachment to coenzyme A to form acetyl CoA.
Cellular Activity 3. Electron transport chain and chemiosmosis pathway- Here we observe that electron carriers such as NADH and FADH2 that are carrying electrons are removed during oxidation steps gets to the electron transport chain and loss their electrons to the chain. 
As electrons move along the chain, the energy they lose as they are sequentially made accessible to lower-level electron carriers and electrons eventually to the final electron acceptor is clipped for ATP production.
