The correct answer is (a) driving.
The pressence of undesirable substances in air is called as air pollution. There are many human activities that contribute to air pollution. The biggest contributor is driving. The pollutants that comes out of the car are carbon dioxide, carbon monoxide. They also release hydrocarbon and nitrogen oxides which when combines in sunlight becomes ozone. Air pollutants emitted by cars and other automobiles increases the level of harmful gases which to severe health problems such as heart disease, asthma, irritation in eyes.
Answer:
the oxygen from the environment will flow into the cell
Explanation:
because by diffusion, areas of high concentration flow to low concentration :)
False, it's extremely difficult for scientists to agree upon what makes relatively close species different when it comes to extremely technical factors. Whether something is simply a single deformation of a specimen/family or the discovery of an entirely new species. However there are species that are concretely defined, like humans, and it's unlikely that evolution will introduce a new version of humanity any time soon - but if it came to be that 5000 years in the future humans were genetically a world different than how we are today, I suspect it would be a long argument on whether or not they should be classified as a new species by their scientific leaders.
Answer:
Motor proteins <em>propel themselves along the cytoskeleton</em> using a mechanochemical cycle of filament binding, conformational change, filament release, conformation reversal, and filament rebinding.
Hope this helps :)
Answer:This is an example of a theory changing because a new scientific method was developed.
