Is there a human carrying capacity on Earth? Explain why or why not.

Biology
1 answer:
ira [324]3 years ago
3 0

Answer: Every species has a carrying capacity, even humans. However, it is very difficult for ecologists to calculate human carrying capacity. Humans are a complex species. We do not reproduce, consume resources, and interact with our living environment uniformly.

In two or three well-developed paragraphs, explain how pollution can come from both natural sources and from human activities. P
spayn [35]

Pollution can come from both natural sources and human activities depending on the type of pollutant.

<h3>What is pollution?</h3>

It is the release of substances into the environment to the extent that the well-being of plants, animals, and humans starts getting affected.

Substances that are released into the environment to the extent that they start affecting the organisms in the environment negatively are known as pollutants.

Pollutants can come from natural sources or as a result of human activities.

For example pollutants such as oxides of sulfur, methane, carbon dioxide, etc. can come from natural processes such as volcanic eruptions, activities of microbes, etc.

Pollutants such as oxides of carbon and sulfur can also be generated as a result of human activities such as the burning of coal, technological inventions, etc.

What are the products of aerobic respiration?
bixtya [17]
I am confused as to what your question is specifically asking but the chemical formula for aerobic respiration is:

Oxygen + Glucose --------> Carbon Dioxide + Water
O₂ + C₆H₁₂O₆ --------> CO₂ + H₂O

Hopefully this will aid you in answering your question :)

To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible location
kramer

Answer:

The correct representation is attached with the explanation.

Explanation:

In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.

During aerobic respiration, the energy within the bonds of a glucose molecule is released in small amounts in a step-by-step, en
Rus_ich [418]

Answer: In this process, the energy released in form of ATP (Adenosine triphosphate) is used to POWER BIOCHEMICAL PROCESSES.

Explanation:

Aerobic respiration is the process by which living organisms breaks down glucose molecule to release energy. Oxygen is used for this process that's why the name aerobic.

Aerobic respiration releases energy within the bonds of glucose step by step in an enzyme controlled reaction. The stages of these processes includes:

--> Glycolysis: In this stage, glucose molecules are split to produce two molecules of ATP and two molecules of NADH (another energy carrying molecule).

--> Krebs Cycle: this is the second stage which occurs in the mitochondria of cells. The 2 ATP molecules generated from glycolysis is used to produce two more ATP, 8 more NADH and 2 molecules of FADH. This makes it a total of 16 energy molecules ( including 2 molecules of ATP from glycolysis).

--> Electron transport chain: this is the last stage of aerobic respiration which takes part at the inner member of the mitochondria. Electrons are transported from molecule to molecule down an electron-transport chain. Some of the energy from the electrons ( NADH and FADH from kreb cycle) is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. As a result 32 more ATP are generated.

In conclusion, a total of up to 36 molecules of ATP from just one molecule of glucose in the process of aerobic respiration which are used to power biological processes.
