Answer: C. Multi-celled eukaryotic organism began to diversify
Explanation:
The Proterozoic is an eon. There were multiple organisms that appeared in this eon. They perform the process of photosynthesis which resulted in gradual pilling up of oxygen into the atmosphere, thus changing the composition of the atmosphere and setting up for future organism.
Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
The incidence rate of active TB cases for the 6-month period was 130 per 100,000 population.
<h3>How to calculate the incidence rate?</h3>
The incidence rate is calculated as the number of new cases of the disease reported divided by the resident population in the place and year, multiplied by 100,000 inhabitants.
With this information, we can conclude that the incidence rate of active TB cases for the 6-month period was 130 per 100,000 population.
