Pseudoscience is literally just FAKE SCIENCE. remember that
The sixth mass extinction unlike the previous mass extinctions, it is due to human actions. For example exotic species introduced by humans into new habitats. like the brown tree snake or peregrine falcon; They may carry disease, prey on native species, and disrupt food webs. Often they can out-compete native species because they lack predators. For instance the brown trees snakes; hitch-hiked from their native Australia on ships and planes to Pacific Islands such as Guam. Lacking local Islands predators, the snakes multiplied quickly. They have already caused the extinction of many birds and mammals they preyed upon in their new island ecosystems.
The answer would be A. carbohydrates (carbs) because carbs are generally composed of sugars and glucose (as an example) has the ratio between carbon, hydrogen and oxygen in a 1:2:1 ratio in its form: C6H12O6
Divide the mass of the object by its volume to yield the density of the object. For example, the object density = mass / (Vf – Vi). Compare the measured density to that of pure gold (19.3 g/cc) to determine whether the object is made of pure gold.
