Which of these changes to the cell would cause the greatest reduction in the activity of catalase? A. A decrease in the concentration of hydrogen and oxygen B. An increase in the concentration of hydrogen peroxide C. A strong bonds between carbon atoms that cannot be broken D. Ionic bonds between carbon atoms and oxygen atoms
Answer:
A. A decrease in the concentration of hydrogen and oxygen
Explanation:
Catalase's function is to catalyze the decomposition of hydrogen peroxide (H₂O₂), which is a toxic substance for cells, into oxygen (O) and water (H₂O).
The following chemical reaction can represent the catalase enzymatic action:
2H₂O₂ + Catalase → H₂O + O₂
Due to this, as oxygen and hydrogen (H) are structurally essential for the catalase reaction, the decrease in the concentrations of these substances would also reduce the enzyme's action potential.
how would a plant cell function if it did not contain chloroplasts?
Without chloroplasts the plant would probably die
Because chloroplasts are used for photosynthesis, which gives the plant food and energy it needs to survive and without them the plant can't get any food/nutrients

b) Type a second paragraph comparing the accuracy of your model to actual organ systems and
their functions.
i.
Consider how a model is different from an actual human body.
ii.
Describe the limitations of a model.
Answer:
In comparison to the real thing, a model can help you visualize or picture in your mind something that is difficult to see or grasp, as well as express ideas and understand the process. Models, on the other hand, cannot incorporate all of the features and accuracy of an actual human body part since they must keep it simple enough to understand, which limits the models, despite their value.

how can we conserve our natural resources in the environment?
Answer:
Switching to sustainable energy sources such as solar power, hydroelectric power and wind power can reduce the amount of fossil fuels being used up. Fossil fuels are natural resources from the environment, but when burned the waste product of it is released into the environment and can potentialy affect other natural resources. Switching to a renewable energy source can help conserve natural resources. Renewable energy sources can be used to harness the energy we need without producing harmful products that affect the environment and it's resources.

The phospholipids of plasma membranes are amphipathic: they have both hydrophilic and hydrophobic regions. The hydrophobic core of the plasma membrane helps some materials move through the membrane, while it blocks the movement of others. How does the structure of the cell membrane help to enable its function?
Answer: The structure of cell membrane is semi-permeable which allows it to pass only certain molecules.
Explanation:
The phospholipid bilayer includes phospholipids that are tightly packed. This membrane is semi-permeable in nature and it can be said that it is selectively permeable. Across this the small, nonpolar materials can pass through as lipid tails of the membrane are nonpolar in nature. Examples of the molecules that can pass through the lipid bilayer are oxygen, carbon dioxide, and others. But the water soluble molecules need assistance of nonpolar molecules to pass through it like glucose, and amino acids as they are oppose by the hydrophobic tails.
