The gasoline engine where the air and fuel mixture is burned is called the combustion chamber. A piston is used to increase and decrease the volume which prepares the fuel to be mixed with air. A spark plug is ignited then to create the combustion thereafter.
False, that's actually backwards I believe.

Answer:
Yes, the humans are invasive species.
Explanation:
The homeland of the modern day humans is Africa, thus they are native o the African continent. But the humans started to spread gradually, first in Eurasia, and later in Australia, North America, South America, and the Pacific islands, to a point now where they have reached pretty much every corner of the world. This is a textbook example of an invasive species that has entered into new ecosystems. Not just that the humans were entering into new ecosystems, but they also were changing the ecosystems, more often then not causing a lot of damage on them, leading to the destruction of lot of habitats and extinction of lot of species.
Answer:
The correct answer is "Odorant-binding proteins (OBPs); Olfactory receptors (ORs)".
Explanation:
Odorant-binding proteins (OBPs) are low-molecular soluble molecules that are secreted in high amounts in the nasal mucus layer. The precise biological activity of OBPs remains unclear, however, its solubility and ability to attach to hydrophobic odorant molecules suggest that they acts as carriers. A second class of proteins called olfactory receptors (ORs), act at the genetic level by initiating transduction once odorant molecules attach to them. ORs are coded by the largest family of genes, which include more than 100 genes and pseudogenes that represent around 3% of the genome.
