Answer:
This question have two parts.
Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?
Answer:
Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.
Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?
Answer:
Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.

Answer: Pentose phosphate pathway produces ribose-5-phosphate sugars that are used in the production of DNA and RNA molecules.
Explanation: Pentose phosphate pathway takes place in the cytosol like glycolysis, with its end products being ribose-5-phosphate sugars and NADH used in production of RNA and DNA.
Difference between these pathways are that the pentose phosphate is anabolic. It uses alot of energy, NADPH and ATP for building. Unlike glycolysis its primary function is not energy production, which on the other hand glycolysis is catabolic, primarily leading to the the production of energy.
Answer:
Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.
Explanation:
undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.
Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.
Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.
Answer:
A & B
Explanation:
Same amount of protons but different numbers of neutrons.
Answer:
hyrdotropism- plant grows toward water.
tropism- growth/movement of an organism in response to a stimulus
phototropism- plants response to light
gravitropism- plant roots grow down in response to gravity
geotropism- plants response to gravity
thigmotropism- plants response to contact of solid object. wraps around solid objects
