Inside a roach's abdomen, a tube-like heart moves blood to organs and tissues. Unlike human blood, a roach's blood doesn't use hemoglobin to carry oxygen, so it is colorless instead of red. The blood also doesn't travel through an extensive circulatory system. Although an aorta carries ...
An oxygen sensor in the exhaust stream makes sure there is enough oxygen available for the catalyst to work and adjusts things if necessary. Besides gas, what else powers your car? The electrical system consists of a battery and an alternator. The alternator is connected to the engine by a...
One of the most common mistakes made by new weed growers is to conduct spur-of-the-moment experiments and hurt or even kill their plants. You should always at least do a quick google search before you try any new technique. Why make your plants be the guinea pig of an experiment that ...
– that’s actually caused by various species of anaerobic bacteria (bacteria that don’t need oxygen to survive). Anaerobic bacteria are often pathogenic, causing disease and illness in larger critters that ingest them. In an oxygenated environment, anaerobic bacteria can not survive or proliferate...
5.A leaky manifold gasket or a cracked header can also leak air into the exhaust system, fooling the oxygen sensors. Another quick test is to fill the exhaust with smoke. Surprisingly, a leak can admit a fair amount of air without making a noticeable exhaust noise. ...
An essential family of PRRs is the inflammasome sensor family, cytosolic proteins that upon activation trigger inflammatory signaling and cell death. Inflammasomes are multiprotein complexes that consist of a sensor, the adaptor protein ASC, and caspase-1; these components assemble following sensor activ...
Bar-headed geese are the SR-71's of the avian world, soaring to 26,000 feet. To learn how their bodies function so well at altitude researchers raised a gaggle of geese, introduced them to a wind tunnel, strapped tiny masks to their beaks and sensor pack
This small hole allows air trapped under the thermostat to vent out of the engine. This makes refilling the cooling system easier. Service Tip:If an engine overheats after you have refilled the cooling system, there may be some air trapped under the thermostat. An old mechanic's trick is ...
If the coolant contains silicates (conventional green antifreeze), it can also foul the oxygen sensor and catalytic converter. If enough coolant leaks into the cylinder (as when the engine is sitting overnight), it may even hydro-lock the engine and prevent it from cranking when you try to ...
As in the trachea, the book lungs exchange oxygen and carbon dioxide through diffusion. Spider Blood The spider's blood, called hemolymph, circulates oxygen, nutrients and hormones to the different organs in the body. Unlike humans, spiders have an open circulatory system. The spider's simple ...
