<u>Answer:</u>
The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for active transport processes to occur with fluids.
<u>Explanation:</u>
- The proximal tubule is a part of the nephron and it controls the "pH of the filtrate" by exchanging "hydrogen ions for bicarbonates".
- It also secretes organic acids like creatinine and bases to be mixed with the filtrate, so that it is neutralized.
- Thus it helps in the transportation of the filtrate and is also responsible for absorption and re-absorption of the fluids.
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Answer:
A molecule of DNA is made up of two strands which are joined by the hydrogen bonds present in the nucleotide bases. The sugar and phosphate make up the backbone of the DNA. The sequence of the nucleotide bases determines the traits that an organism will carry. Genes are hereditary molecules which are made up of sections of DNA. Together, they make up the entire genome for the organism. Each gene is located on a specific place inside the chromosomes. The chromosomes are the element of reproduction as they undergo the process of meiosis and duplicate themselves.
