The 10x objective... it's not zoomed in all the way, but it will provide a large field of vision to locate the specimen. Then after it's located you switch to the 40x objective to zoom in on a the specimen to observe it.
A catalyst increases the rate of reaction by providing a metabolic pathway that requires less energy. There for they work by decreasing the activation energy of a reaction.

Answer:
Answer is given below:
Explanation:
Urine is a metabolic nitrogenous waste which is produced from cell metabolism. It contains urea which is a non-toxic molecule formed from toxic ammonia and carbon dioxide. Other constituents of urine are water, chloride, sodium, potassium, creatinine and other dissolved ions. Whereas, feces is non-metabolic waste. It is undigested food produced in the digestion process. Feces contains 75% water 25 % solid matter. Solid matter consists of cellulose, cholesterol, other fats, inorganic substances and dead bacteria. Urine does not contain any bacteria.
The RNA world is a hypothesis associated with the emergence of life on Earth and it is important because states that RNA had catalytic functions.
<h3>What is the RNA world?</h3>
The RNA world is a scientific theory that states life began as primitive organisms in which the RNA played a dual function, i.e., as genetic material and as an enzyme.
The RNA world theory is sustained by the presence of ribozimes, i.e., enzymes composed of RNA instead of proteins.
In conclusion, the RNA world is a scientific hypothesis associated with the emergence of life on Earth and this theory is important because it states that RNA had catalytic functions.
