Hello good afternoon...God bless :) here is the answer to your following question...
Explanation:
Osmosis is important to cells because it allows them to maintain water homeostasis. The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
 
        
                    
             
        
        
        
Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
 
        
                    
             
        
        
        
The best question for this experiment is How does the composition of the soil affect the pH of the rainwater?.
<h3>What are the best factors being studied?</h3>
The main factors based on the description are:
- The pH of the rainwater: This is the factor manipulated by the researcher.
- The aluminum concentration: This is the factor researchers are evaluating.
<h3>What is the best question?</h3>
The best question would be one that relates the main two factors. Based on this, the best question would be: "How does the composition of the soil affect the pH of the rainwater?".

This is because the cilia cells are in desperate need of energy. They get this source of energy from the mitochondria. Also, goblet cells have ribosomes because they need proteins and catalysts to function
