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.
High concentration and passive transport
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove. The fire's heat causes molecules in the pan to vibrate faster, making it hotter.
