The most widely used renewable energy source is hydropower. While this has many benefits, it also causes many environmental concerns when the dams get built.
Answer:
Urine
Explanation:
A filtrate is formed after reabsorption occurs in the nephron of the kidney. Reabsorption of some salts and water accurs at the distal convulated tubule. The filtrate then moves into the proximal convulated tubule where selective reabsorption occurs also. The filtrate is then passed into the collecting duct. From the collecting duct, the filtrate now called<u> urine</u> enters the pelvic of the kidney into the ureter to the urinary bladder.
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.
