<h2>B) is the correct option </h2>
Explanation:
- Succinate dehydrogenase is the smallest component of electron transport chain and consists of four different subunits including FAD, 3 Fe-S centers
- It catalyzes oxidation of succinate to fumarate and electrons released transferred to ubiquinone
- Succinate dehydogenase transfer electrons from succinate to ubiquinone via FADH2 thus this complex directly links tricarboxylic acid cycle to electron transport chain
- Activity of succinate dehydrogenase is inhibited by malonate which is a competitive inhibitor as a result oxidation of succinate to fumarate will not occur and hence concentration of fumarate will decrease
One reason why a species may go extinct is due to environmental changes. For example, if a environment undergoes deforestation / wild fires it’s environment will no longer be grassy green and would not allow for an animal like the Japanese rat snake to use its green coloring to camouflage from predators
Answer:
heres what i found
Explanation:
Arctic tundra are found on high-latitude landmasses, above the Arctic Circle—in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example—or on far southern regions, like Antarctica. Alpine tundra are located at very high elevations atop mountains, where overnight temperatures fall below freezing.
