Answer:
The proximal tubule of nephron in the kidney is composed of single layer of cuboidal cells that are covered with striated borders.
Explanation:
Proximal tubules or proximal convoluted tubule is an important part of vertebrate kidney which is located between bowman's capsule and loop of Henle.
Proximal tubules are divided into 2 parts- Proximal convoluted tubules and Proximal straight tubules.
Proximal convoluted tubules are located entirely to the renal cortex and the Proximal straight tubules descend into the outer medulla.
The major function of Proximal tubules are mainly absorption and secretion.
The proximal tubules helps to regulate the pH from the filtration and also causes sodium reabsorption that is driven by P type ATPase.70% re absorption of sodium takes place in the proximal tubules through active transport.
Moreover elimination of ammonia takes place through proximal tubules by breaking glutamine to alpha ketoglutarate.
www.chegg.com/homework-help/questions-and-answers You recently discovered four new chemical mutagens (#1 - #4), but you do not know what type(s) of mutations these chemicals induce. You exposed E. coli to each chemical individually and observed mutant phenotypes. You then exposed this bacteria to a second known mutagen to observe if the mutations from chemicals #1 - #4 could be reversed. Your data is presented below. Mutations Induced by Mutations Reversed by Chemical EMS Acridine Orange 5-Bromouracil #1 No Yes No #2 Yes No Yes #3 Yes Yes Yes #4 No No No What type(s) of mutations are likely produced by chemical #3? A. transversions B. transitions C. frameshifts What type(s) of mutations are likely produced by chemical #4? A. transversions B. transitions C. frameshifts (SELECT ALL THAT APPLY)
