Explanation:
When humans and animals die. How is phosphorus returned to the soil? Living things could die if the matter could not cycle through ecosystems.
Additional Information: The phosphates in plants and animals are returned to the water when the plants and animals die and decompose. Also, large amounts of phosphorus in the form of phosphates are carried by rivers and streams as runoff to the ocean.
In ecosystem, without the right nutrients in the right amounts, you can't live. Other animals and plants also need the right nutrients to live.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
An ecosystem is a community of living organisms (plants, animals and microbes) in a particular area. The term `eco' refers to a part of the world and `system' refers to the co-ordinating units.

What is the general shape of the graph?
Cell division gizmo
Answers
Answer and Explanation:
The image attached below presents the general shape of a graph showing cell division. This is because this graph shows the diversification of the amount of DNA in a cell in relation to the time and phases of cell division.
Through the graph shown below, we can see that before cell division, the cell passes through the G1 phase, where it has a specific amount of DNA for a cell in that cell stage. During phase S there is a progressive increase in the amount of DNA, and at the end of that phase, the cell will have twice as much DNA as it had before. The end of phase S, starts phase G2, where the amount of DNA is stabilized, until cell division occurs (represented in the graph by the letter M). Cell division causes a progressive decrease in the amount of DNA, which returns to the amount shown in phase G1.

Human, cat, whale and bat have similar forelimb bone structure with a different functions. These homologous structures show
Answers
Answer:
The correct answer is - that They share a common ancestor.
Explanation:
The bones of forelimbs of whale, bat, cat, and human are similar in structure due to the fact they are homologous organs. Such organs which have the same basic structure but play a different role in their respective bodies are called homologous organs.
These organs are developed from the same organization during their development but due to evolutionary change in their environmental condition and their requirement, these organs are modified to perform different functions. The homologous structures are end result of divergent evolution which means they show common ancestry.

Answer:
C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
Explanation:
It's not A, because that's the nervous system, not endocrine.
It's not B, because homeostasis = balance, and not stopping production isn't balance

All of the possible sources of acid rain are Sulfur dioxide is released into the atmosphere by the burning of fossil fuels; gases are released from volcanic eruptions; and nitrogen dioxide is released into the atmosphere by the burning of fossil fuels, so all the first, second, third, and fourth options are correct.
What is acid rain?Acid rain is a type of rain that has a lower pH level than normal rainwater and occurs when emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOx) react with atmospheric moisture to form sulfuric acid (H₂SO₄) and nitric acid (HNO₃). Acid rain can have harmful effects on the environment, including damaging forests, lakes, and aquatic life, and the primary sources of sulfur dioxide and nitrogen oxides are the burning of fossil fuels, such as coal and oil, in power plants, factories, and vehicles.
Hence, all the first, second, third, and fourth options are correct about the acid rain.
