Answer:
Quarks pair with other quarks to form protons and neutrons.
Explanation:
Every atom contains a nucleus and within the nucleus, protons and neutrons are present. A quark is the fundamental particle of a matter. Quarks are joined together to form hadrons. Protons and neutrons in the nucleus of an atom are hadrons. Thus, quarks are the smallest particle of a matter as believed by most of the physicists.
Answer:
photosynthesis
Explanation:
Chlorophyll a absorbs the wavelengths of violet-blue and orange-red light and functions as a primary electron donor during the election transport chain in photosynthesis. It also functions in transporting energy to the reaction center where P680 and P700 are located.
Enzymes can either help break a substrate molecule down to smaller ones or help substrate molecules join to form a larger one. They work as catalysts by reducing the activation energy of the reaction by providing an alternate pathway for it. The enzymes are specific with their substrates.
The enzyme becomes denatured when this occurs.
The roads might of had been build where an animal was living and there also might be pollution due to the cars.
