Explanation: By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) from the engine into less harmful carbon dioxide (CO2), nitrogen and water vapour.
From what I know, nicotine is a stimulant. It's not much, but I hope it gets you close to a answer. :3
Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

Explanation:
Answer:
plasma membrane protein on the eosinophil's surface
Explanation:
Eosinophils sometimes called acidophils are a part of the immune system. The responsible for fighting viral infections and parasites. Eosinophils expresses IgE- binding protein and a protein toxin, cathepsin on the plasma memberane surface along with the SNARE complexes.
Therefore, binding of an eosinophil to an antibody-coated parasitic worm involves binding of the antibody's stem region to a plasma membrane protein on the eosinophil's surface.
Answer:
Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.
