Answer:
Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. ... When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere.
Explanation:
Answer:
spend time removing introduced species, which can mean physically weeding invasive plants or trapping invasive animals. ... Others work to reduce harvesting directly or to reduce the incidental catch of nontarget species.
This probably is Yeast cells they can respire both aerobically and anaerobically. they prefer the presence of oxygen as aerobic respiration produces more energy that anaerobically and produces less waste products than anaerobic respiration.
hope that helps
Answer:
2 electrons
Explanation:
According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.
Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.
