Answer:
b. glycolysis
Explanation:
Anaerobic glycolysis is a catabolic route used by many types of cells for the degradation of glucose in the absence of oxygen. That is, glucose is not completely oxidized to carbon dioxide and water, as is the case with aerobic glycolysis, but fermentative products are generated.
It is called anaerobic glycolysis since it takes place without the presence of oxygen, which in other cases functions as the final acceptor of electrons in the mitochondrial transport chain, where large amounts of energy are produced from the processing of glycolytic products.

Sulfur emissions from industry combine with water in the atmosphere and form acid rain. A new factory is built very close to the lake that Josh visits often. By examining the table that shows what pH range different species can survive, Josh decides that the aquatic life will be affected by the changes in pH that the lake. Josh correctly decides that organisms that will be the most affected are
A) perch and frogs.
B) mayfly and bass.
C) snails and clams.
D) frogs and salamanders.
The correct answer is option (C) snails and clams.
Acid rain is formed when oxides of sulfur and nitrogen combine with water molecules. Industries are one of the major contributors to acid rain. pH is a measure of acidity or alkalinity in water.
A factory built close to the lake can cause acid rain which affects the pH of the lake. Any change in the pH of the lake has an effect on the organisms in it. A pH of 7 is considered to be neutral and pH values below 7 indicates acidity and pH values above 7 indicates alkalinity. Organisms have an acid tolerance level beyond which they are affected and can die. Perch has an acid tolerance of up to pH 4.5 and frogs can tolerate an acidic pH of 4.0. The acid tolerance level of Mayfly and Bass is a pH of 5.5. Salamanders can tolerate an acidic pH of 5. Whereas, Snails and Clams have a very less pH tolerance of 6. They are highly susceptible to acidic pH.
Thus, Josh correctly decides that organisms that will be the most affected are snails and clams.
"<span>The second part of the mitotic phase, during which cell division is completed by the physical separation of the cytoplasm components into two daughter cells is called telophase."
Telophase is the last phase of mitosis. The name itself indicates terminal (telo) phase. </span>The chromosomes get to the cell poles and nuclear membranes are formed around each set of chromatids. The actual cell division is called c<span>ytokinesis and it starts at the end of the telophase.</span>
This figure illustrates 3 hypotheses of how a cancer stem cell may arise: (1) A stem cell undergoes a mutation, (2) A progenitor cell undergoes two or more mutations, or (3) A fully differentiated cell undergoes several mutations that drive it back to a stem-like state.
