Answer:
C
Explanation:
ecosystem is living AND non living things
The best definition of an ecosystem is option C: "A system formed by the interactions of living organisms with the nonliving physical environment."
What is an ecosystem?An ecosystem is a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their nonliving environment, including the atmosphere, soil, and water.
This interaction creates a functional system that can be characterized by energy flow and nutrient cycling. The other options are not accurate definitions of an ecosystem, as ecosystems involve both living and nonliving components, and the interactions are not limited to a single species.
Ecosystems are not isolated, and they can interact with other ecosystems. For example, rivers and streams can transport nutrients and organisms downstream, connecting different ecosystems such as a forest and a freshwater system. Similarly, the atmosphere can transport pollutants and other materials across vast distances, affecting ecosystems far from their source.
In summary, an ecosystem is a complex, interconnected system where living organisms interact with each other and the non-living components of their environment. Understanding the functions and interactions within ecosystems is critical to developing effective management strategies for conserving biodiversity and maintaining the ecosystem services that humans depend on.

A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
What is baseline imbalance?This is simply known as a form of art that pertains to systematic error when producing an intervention groups in any clinical trial. In this type of imbalance, the groups differ in baseline traits due to the fact that the participants were selected or assigned.
There are different ways to balance a load. Why is the figure considered to be an example of a negative feedback system as opposed to a positive feedback system is that The figure shows the correction of an imbalance back to a baseline.

Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.

Location A
Location B
Location C
Location D
Answer:
location b is the answer
At location B in the diagram, the granite is likely to be formed. so, the correct option is (B).
What is Granite?
Granite is a coarse-grained intrusive igneous rock which is composed of quartz, alkali feldspar and plagioclase. It is formed from magma with a high content of silica and alkali metal oxides which cools slowly and solidifies underground.
It is a light-colored plutonic rock found throughout the continental crust, mainly in mountainous regions consisting of coarse grains of quartz, potassium feldspar and sodium feldspar. All these minerals make up more than 80% of the rock.
Granite is used in counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments.
Thus, at location B in the diagram, the granite is likely to be formed. so, the correct option is (B).

why CO2 still being produced for a few minutes after death?
Explanation:
As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.
During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
Answer:
Nucleolus
Explanation:
This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.
The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.
What is nucleolus?The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.
The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.
It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.
The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.
It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.
Thus, the correct option is 1.
