Which of the following alternative engery technologies is most likey to be used to power a car?

wind
geothermal
biofuel
hydropower

The correct answer to the question is Biofuel

Explanation:

Biofuel can be used as an alternative energy technology source to power a car.

The importance of using biofuel is that it causes less air pollution than fossil fuels, and  it has less effect on the global warming. Most importantly, it is produced from agricultural sources.

The biofuels that can be used are butanol,ethanol and biodiesel etc.

Wind, geothermal and hydropower can not be directly used to provide power to the car.

Hence, the correct answer to the question is that biofuel which can be used as an alternating technology to provide power to car.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
