HydrogenWhich statement describes the electron sharing between two oxygen atoms?
Each oxygen shares one electron with the other.
Each oxygen shares two electrons with the other.
Each oxygen shares eight electrons with the other.
Each oxygen shares six electrons with the other.
When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.
What is Electrons?A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). The nucleus of an atom is made up of electrons, protons, and neutrons together.
The positive charge of a proton balances the negative charge of an electron. An atom is in a neutral condition when it has the same number of protons and electrons.
There are several ways in which electrons differ from the other particles. They are substantially less massive, exist outside of the nucleus, and show both wave- and particle-like properties.
Therefore, When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.

Which of these chemicals is not a pollutant?
A. Methane
B. Nitrogen gas
C. Nitrate
D. Carbon dioxide
Answer:
All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate
Explanation:
A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.
B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.
C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.
D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.
I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate

Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.

PLS HELP FAST!!!! You have a natural-gas (methane, CH4) stove. When you ignite a natural-gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. Write a balanced equation for this reaction, and be sure to show your work. (6 points)
Answer:
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Explanation:
The balanced equation for the reaction of methane with oxygen is CH₄ + 2O₂→CO₂ + 2H₂O.
What is methane?Methane is a gas and a chemical compound with formula CH₄. It is a colorless and odorless gas and very flammable. It is made up of carbon and hydrogen. Methane comes under greenhouse gas.
As it is highly reactive, it reacts with the gases present in the environment. Here, methane is reacting with oxygen. When one molecule of methane reacts with two molecules of oxygen, it produces carbon dioxide and two molecules of water.
The reaction happens in the presence of heat and high temperature. The balanced reaction is written when the same number of moles are present on both sides of the reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O.
Thus, the balanced equation for the reaction CH₄ + 2O₂→CO₂ + 2H₂O CH₄ + 2O₂ → CO₂ + 2H₂O.

How does the Golgi Body and Plasma membrane work together ?
Answer/Explanation:
The Golgi body is a system of flattened sacs that is involved in the packaging, modification, and transport of proteins. It is particularly important for proteins that have to be transported outside of the cell.
Proteins from the Golgi that are to leave the cell are transported in vesicles. When they reach the membrane, the vesicles fuse with it and release the proteins outside of the cell
What happens to matter and energy in the process of photosynthesis?

A food chain in an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish.
The primary consumer would is freshwater snails.
Explanation:
Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often get killed by secondary consumers.
Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.

2. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
3.Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems. (Not from google )
Answer:
1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.
Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.
