Answer:
This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:
1) GEL
2) DYE
3) DNA MARKER
4) LID
Explanation:
This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.
In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.
Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.
Answer:
Direct relationship.
Explanation:
There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.
D) different organs that work together to carry out a function
hope this helps! please mark brainliest!:)
Well I don’t know if this is much help but bacteria, unlike plants and animals, are unicellular, they only have one type of cell.
Monomer of nucleic acid is Nucleotide.
Nucleotide is made up of three components namely- Nitrogenous base, pentose suger and phosphate group.
Depending upon the nucleic acid,i.e RNA or DNA, nucleotide can be Ribonucleoside triphosphate (rNTP) and deoxyribonucleoside triphosphate repectively (dNTP).
