Typically when we think about extreme weather, we think about the effect of weather on humans and other life forms. However, weather events also greatly impact non-living things. Freeze and thaw cycles tend to break up rocks, weathering them physically. Landscape erosion can be greatly enhanced by storms because rivers and streams are able to transport larger amounts and larger sizes of material than they otherwise would, due to faster flow velocities. Sand at beaches is carried away by strong storms until it can be replenished over time. Sediments become hydrated during rainfall events, which can result in landslides and land movement. Many of these processes can create hazards for humans, but the physical landscape is very much shaped by extreme weather events. Weather is weather, which is nonliving. Erosion is affected by weather, the more rain there is, the more erosion. The more temperatures change, the more erosion because things swell as they warm up and shrink as they cool off, which can cause them to break.
Hurricane affects come from both wind and water impacts. Wind and waves break coral, damaging it or forcing it on shore and disrupting the ocean ecosystem. Fish and benthic organisms face turbulent conditions due to waves and wind. ... Winds dislocate sea and migratory birds caught in the eye of the storm.
Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes. Living things are defined by a set of characteristics including the ability to reproduce, grow, move, breathe, adapt or respond to their environment. Extreme heat causes lakes and rivers to dry up. Some kinds of earth can also dry up so much that it gets cracked.
Extreme rainfall causes floods and landslides.
Extreme cold can cause rocks to break, when the water that leaked into cracks in the rock freezes and expands.
If I knew more about the water cycle, I might be able to tell you more about how extreme weather affects clouds and other parts of the water cycle.
Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.
- The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
- It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
- An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
- The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
- An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.

Answer:
d. it diffuses into mitochondria to be broken down to generate ATP
Explanation:
When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.
The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.
