Answer:
3.) It is polar
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. Other molecules, such as Ethane, are nonpolar, having neither a positive nor a negative side.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.

Suppose we completely stopped burning fossil fuels immediately. How many years would it take to return to atmospheric CO2 levels from the year 1800, about 600 GtC? Use the Gizmo to find the answer.
Answer:
Explanation:
It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.
As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.
Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.
What is co2 quantity ?Since 2000, the worldwide atmospheric carbon dioxide quantity has grown with the aid of using 43.5ppm, an growth of 12 percent. The contemporary-day document of atmospheric carbon dioxide degrees commenced with observations recorded at Mauna Loa Observatory in Hawaii.
Thus it is well explained.

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

what is an acid? What is a base?
Answer:
An acid is a substance that donates hydrogen ions. Now there are more hydrogen ions than hydroxide ins in the solution. This kind of solution is acidc. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.
Explanation:
Answer:
An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.
Explanation:
An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond.
A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

HydrogenCompare the Viking 1 and 2 probes to the Pathfinder probe that landed on Mars in 1997. How was their technology different?
Answer:
Explanation:
In 1976, The Viking 1 and Viking 2 probes landed on Mars. For six years they transmitted fascinating panoramic views of the red and rocky soil of Mars back to Earth. Twenty years passed before a third probe landed on Mars. In 1997, the Pathfinder probe landed a miniature vehicle named Sojourner on the planet. The probes operated for three months and sent back large amounts of data on the Martian environment. At the same time, the Mars global surveyor probe was placed in orbit to take an overall portrait of the planet. It supplied hundreds of thousands of bits of information, especially on climatic variations.
Answer:
Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem
Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.
Explanation:
hope it helps :)
The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:
The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.
The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.
The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.
The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.
Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.
In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.
On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.
Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.
