Explain the role of living things such as yourself in the nitrogen cycle
Simple answer please
Answer:
Role of organisms in the nitrogen cycle:
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Explanation:
I THINK THIS IS SHORT AND EASY
Plants use nitrates to create proteins. Animals eat plants for protein. Humans add nitrogen-rich fertilizers and manure to the cycle.
What is nitrogen cycle?The process by which nitrogen is changed into a variety of different chemical forms as it cycles through different ecosystems, including the atmosphere, land, and ocean, is known as the nitrogen cycle, which is a biogeochemical cycle. Both biological and physical methods can be used to complete the transformation of nitrogen.
In order to synthesize proteins, plants must first take up nitrates from the surrounding soil. Plant material is digested by animals, which then contributes to the formation of animal protein. Both the addition of nitrogen-rich fertilizers to the soil and the utilization of manure are examples of how humans make a contribution to the cycle.

A. When the guard cells are full of water, they become stiff and hold

Two guard cells make up the stomata. The walls of these cells are thicker on the inside than they are on the outside. Stomata open when they take in water and close when they lose water due to the unequal thickness of the paired guard cells.When stomata open, they release water vapor and other gases into the atmosphere, including oxygen.A.

What role have nitrates and phosphates played in damaging Muddy Creek?
Answer:
Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.
Explanation:
Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.
Nitrates and phosphate found in water are usually from plants that have been washed off by rain water and also from vehicles' exhaust.
When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).
This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a swamp and eventually a meadow

i took the k-12 test
The scenario which describes a relationship of parasitism is a tick feeds on the blood of a dog. Therefore, the correct option is D.
What is parasitism?In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this scenario, the tick benefits by feeding on the dog's blood, while the dog is harmed by the loss of blood and potential transmission of diseases by the tick.
Option A describes a mutualistic relationship, where the ox pecker birds benefit by feeding on the ticks, and the zebras benefit from having the ticks removed.
Option B describes a predator-prey relationship, where the polar bear benefits by catching and eating the seal, while the seal is harmed by being eaten. Option C and D describe commensalism. They both are same. Therefore, the correct option is D.

A semi permeable membrane is placed between two solutions the membrane is only permeable to water on the right side is a 10% salt solution on the left side is distilled water 100% water in which direction will the net movement of water occur
Most water molecular move from x to y decreasing the concentration gradient of sucrose. The solution will always move down the concentration gradient.
This means the water always move from this is more water to where there is less water.
Therefore, water will move from a hypotonic solution to the hypertonic solution.

7 Identify- By what process did these cells form?
Answer:
Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Explanation:
Hope this helps
Cells can form through a process called cell division.
What is cell division?In cell division, a single cell divides into two or more daughter cells. This is the primary way in which living organisms grow and develop, as well as repair damaged tissues and replace old or dying cells. Cell division can occur through two main processes: mitosis and meiosis.
Mitosis is a type of cell division that results in two identical daughter cells, while meiosis is a type of cell division that produces four genetically diverse daughter cells, typically used in the production of gametes for sexual reproduction. Other processes, such as differentiation, also play a role in how cells form and develop into specialized types of cells with distinct structures and functions.
