<span>I think the pKa for acetic acid is about 4.74. Therefore Acetic
acid/acetate buffer will work best at 4.74 +/- 1 pH unit and so the pH 8 is far
removed from that. Hence it would not buffer at that pH at all.</span>
Bubbles are observed in the simulation after 1 minute due to the production of oxygen by plants during photosynthesis.
<h3>What is photosynthesis?</h3>
Photosynthesis is the process by which green plants manufacturer their food from carbon dioxide and water using sunlight as am energy source.
In the process of photosynthesis, sugar is produce and oxygen is given off as a by-product.
Oxygen being a gas produces gas bubbles.
Therefore, in the simulation, bubbles are observed after 1 minute due to the production of oxygen by plants.

Answer:
The correct option is B.
Explanation:
Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.
