Answer:
D. nitrogen, carbon, hydrogen, oxygen, sulfur
Explanation:
Proteins are giant organic molecules. The monomers that combines to form proteins are the amino-acids.
The atoms that makes up the amino-acids units of proteins are carbon, hydrogen, oxygen, Nitrogen and sometimes sulphur.
Not all amino acids contains sulfur in their structure.
These atoms are also the atoms that makes up proteins when they are broken down.
Answer:
Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.
Explanation:
- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.
- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.
- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.
- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.
N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.
- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.
- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.

Answer:</h2>
Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h2>
Explanation:</h2>
Mutation assumes a significant job in evolution. A definitive wellspring of all hereditary variety is a mutation. It is significant as the initial step of development since it makes another DNA succession for specific quality, making another allele.
Recombination additionally can make another DNA succession (another allele) for a particular quality through intragenic recombination. Mutation going about as a developmental power independent from anyone else can possibly cause huge changes in allele frequencies over exceptionally significant stretches of time.
