Imagine a muscle cell that undergoes a high degree of contraction. What scenario is likely to describe the activity of glycolysis and the pentose phosphate pathway in these cells? A) It has a low activity of glycolysis and a low activity of the pentose phosphate pathway.
B) It has a high activity of glycolysis and a low activity of the pentose phosphate pathway.
C) It has a high activity of the oxidative phase of the pathway, low activity of the nonoxidative phase, and a low activity of glycolysis.
D) It has a high activity of the oxidative and forward nonoxidative phases of the pentose phosphate pathway, and a high activity of glycolysis.

A person is given a dose of a new drug to address the symptoms of hair loss. After a week, the patient develops acute hemolytic anemia (AHA). Which of the following conclusions can we make?
A) We can't make any conclusions about either the person or the drug.
B) The person does not have G6PD deficiency, and the drug likely prevents oxidative stress in red blood cells.
C) The person may have G6PD deficiency, and the drug likely causes oxidative stress on red blood cells.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
