Which statement is true about nitrogen gas in the atmosphere?
It is easily absorbed and used by plants and animals.
It's taken in by plants as part of their metabolism.
It's unusable by most forms of life on earth.
It's present in only trace amounts.
Answers
The statement that is true about nitrogen gas in the atmosphere is that it is unusable by most forms of life on Earth. Nitrogen gas (\(N_2\)) makes up approximately 78% of Earth's atmosphere, and while it is abundant, it is not directly accessible to most organisms.
Nitrogen gas is composed of two nitrogen atoms held together by a strong triple bond. This bond is difficult to break, and most forms of life lack the necessary enzymes to convert nitrogen gas into a usable form. This inability to directly utilize nitrogen gas is true for both plants and animals.
However, while nitrogen gas is not directly usable, it is a crucial element for life. Nitrogen is an essential component of proteins, nucleic acids (DNA and RNA), and other vital molecules. In order to obtain the necessary nitrogen for growth and development, living organisms rely on the nitrogen cycle.
In the nitrogen cycle, nitrogen gas is converted into biologically usable forms through a process called nitrogen fixation. Nitrogen-fixing bacteria, found in soil and root nodules of certain plants, have the ability to convert nitrogen gas into ammonia (\(NH_3\)) or nitrate (\(NO^3^-\)). These forms of nitrogen can then be taken up by plants as part of their metabolism.
Once incorporated into plants, nitrogen can be passed on to animals through the consumption of plant material. Animals obtain nitrogen by consuming plants or other animals that have already assimilated nitrogen into their tissues.
In conclusion, nitrogen gas in the atmosphere is unusable by most forms of life on Earth. It requires conversion into biologically usable forms through nitrogen fixation by bacteria, and then it can be taken up by plants as part of their metabolism. This indirectly allows nitrogen to enter the food chain and be utilized by animals.

Which of the following processes releases carbon into the air? (5 points)
Answers
Answer:
Explanation:
Combustion of fossil fuels: Burning coal, oil, and natural gas to produce energy releases carbon dioxide (CO2) into the atmosphere.
Other processes that can release carbon into the air include:
Deforestation: Trees absorb carbon dioxide through photosynthesis, and cutting down forests can release the carbon stored in the trees and soil.
Volcanic activity: Volcanic eruptions can release carbon dioxide and other greenhouse gases into the atmosphere.
Decomposition: When organic matter such as plants, animals, and other living organisms decompose, they release carbon dioxide and other gases into the atmosphere.
Ocean outgassing: The ocean absorbs and releases carbon dioxide as part of its natural cycles, and some of this carbon can be released into the air.
It's important to note that while some of these processes are natural, human activities such as burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, leading to climate change.

How does energy move through photosynthesis?
Answers
Answer:
Energy from the sun is absorbed by the chloroplasts in the leaves of a plant. The light energy is converted into chemical energy as the chloroplasts use the light to power the production of glucose from carbon dioxide and water. The glucose is used by the plant to produce energy and build new cells, and any excess glucose is stored as starch. Oxygen is also released as a by-product of photosynthesis.

Name processes in living things that depend on osmosis.
Answers
Answer:
Osmosis is an important process that occurs in living things. The following are examples of biological processes that rely on osmosis:
1. Cellular hydration - Osmosis plays a role in hydrating or dehydrating cells. Water can move into or out of cells via osmosis, depending on the concentration gradient across the cell membrane.
2. Nutrient uptake and waste removal - Cells require nutrients to carry out their metabolic functions and produce waste products that need to be removed. Osmosis is involved in the movement of these substances in and out of cells.
3. Regulation of blood pressure - Osmosis is important in regulating blood pressure. For instance, when the concentration of ions in the blood increases, osmosis causes water to move from surrounding tissues into the bloodstream to restore balance.
4. Root absorption in plants - Osmosis allows plants to absorb water and minerals from soil through their roots. The concentration gradient between the soil and the root cells enables water to move via osmosis.
5. Osmoregulation - This process involves maintaining a balance between water and solute concentrations in living things. For instance, freshwater fish depend on osmosis to expel excess water from their bodies and maintain the right balance of ions, while marine fish drink large amounts of water to balance the high salt concentration in their bodies.
