How would you revise the simulation so users can evaluate the role of human activity in the pH of the ocean? I would add the condition What variables would you add to or change in the simulation to accomplish this?
Human activities such as burning of fossil fuels is the main cause of acidic pH of the ocean.
Explain the role of human activity in the pH of the ocean?The pH of the ocean tends to increase because of human activities that increased levels of carbon dioxide in the atmosphere. This CO2 is dissolved into the ocean and makes the ocean more acidic.
Variable of climate (x) and biodiversity (y) would be added to evaluate the role of human activity in the pH of the ocean.
So we can conclude that human activities such as burning of fossil fuels is the main cause of acidic pH of the ocean.

_____ productivity = the organic materials that remain after photosynthesis organisms in the ecosystem have used some of these compounds for their cellular energy needs (cellular respiration)
The organic materials that remain after photosynthesis organisms in the ecosystem have used some of these compounds for their cellular energy needs called primary productivity.
What is cellular respiration?
Cellular respiration is defined as the process through which organisms combine oxygen with food molecules, converting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, water and carbon dioxide.
Common examples of primary producers include diatoms, coccolithophores and dinoflagellates.

Based on the concept of the global conveyor belt, what happens to ocean water as it moves from Antarctica to the equator?
It transfers thermal energy to deeper layers of the ocean.
It becomes less dense and rises to the surface.
It transfers thermal energy to the area, warming the equatorial waters.
It becomes more dense and sinks to the ocean bottom.
What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.
Concept conveyor beltThe conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.
As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.
Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is It becomes less dense and rises to the surface.

Investigate substances containing carbon or oxygen that relate to biological processes. Explain their main function in those processes.
Answer:
I hope this helps!!!1
Explanation:
Carbon and oxygen are independent of each other but are very closely connected as well as interdependent. The following article will cover information that will help you understand the carbon-oxygen cycle in detail.
Life on planet Earth continues due to the presence of organic as well as inorganic nutrients present in nature. These nutrients need to be continuously recycled. If this doesn’t happen, all the nutritive resources in the world will get extinguished completely. No nutrients means no life on Earmeano, for the life cycle of every living being, unicellular or multicellular organism to sustain, recycling the nutrients is very important. One of the important cycles is the carbon-oxygen cycle.
The Process of Carbon-Oxygen Cycle
There are four steps involved in the completion of this cycle. These methods are discussed below:
Photosynthesis
Plants undergo photosynthesis which helps them produce energy and food for themselves. During this process, plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the energy from the sun, help convert CO2 and H2O into Oxygen O2, sugar, and water vapor. Oxygen (O2) is released by plants as a by-product of the atmosphere.
Formula for Photosynthesis
CO2 + H2O + Light ———-> (CH2O) + O2
The carbon dioxide from air and water from the soil in presence of light (energy) is taken by the plants and converted into carbohydrates and oxygen as by-products.
Respiration
Just as plants carry out photosynthesis, animals carry out respiration. Respiration occurs when animals take in oxygen from the air along with simple sugars from their food. This helps in the release of carbon dioxide, water, and energy from the animal body. During cellular respiration, animals require O2 while inhalation. When they exhale the waste product of cellular respiration, they release CO2 into the atmosphere again.
Formula for Respiration
(CH2O) + O2 ———-> CO2 + H2O + Energy
The carbohydrates taken from food like plants or carbon-based compounds along with oxygen are converted to carbon dioxide which is released into the air along with water and energy during respiration.
Combustion
It is a process of burning that occurs naturally in nature. For example, volcanic eruptions are natural combustion processes where carbon dioxide is released into the atmosphere due to burning. Nowadays, many environmental pollutants cause an increase in the amount of CO2 in the air. These include cars, factories, burning of woods, coal, nuclear energy, gas, etc. This irresponsible combustion and release of excessive carbon dioxide and other harmful gases in the environment is the major contributing factor to today’s global warming.
Decomposition
After the death of any living organism, i.e., unicellular or multicellular organism, it gets decomposed. This decomposition means insects, fungi, and bacteria (together called decomposers), help in breaking down the cellular components of the dead organism into its basic elements. These elements include water, calcium, nitrogen, carbon, and oxygen. Thus, decomposers help in the release of oxygen and carbon dioxide back into the atmosphere as their metabolic waste products.
The entire cycle can be summarized as, plants taking in carbon dioxide and releasing oxygen during photosynthesis. This oxygen released is taken up by animals who release carbon dioxide after carrying out respiration. Thus, the recycling of carbon and oxygen in the atmosphere will continue as long as respiration and photosynthesis occur. This also proves that to sustain life, plants are very important as they are the major contributors to the amount of oxygen present in the atmosphere. Although both cycles occur independently, they are, in a small way, interconnected to each other.
The different processes where carbon and oxygen will combine and help in different biological process are combustion, photosynthesis and respiration.
What is biological process?
A biological process is the organism's genetically designed means of achieving a particular goal. The outcome or final state of biological processes is frequently used to characterize them, for example, the biological process of cell division produces two daughter cells (a divided cell) from a single parent cell.
A biological process is carried out by a specific collection of molecular operations performed by certain gene products (or macromolecular complexes), frequently in a highly controlled manner and in a specified temporal sequence. Oxygen and carbon used in many biological process such as photosynthesis.
Therefore, The different processes where carbon and oxygen will combine and help in different biological process are combustion, photosynthesis and respiration.

A phosphate groupA pentose sugar [deoxyribose]A nitrogen-containing base [adenine, thymine, guanine and cytosine]Thus the first option is the right answer.
Reasons why the other options are wrong:
"A plasma called haemoglobin" is wrong as plasma and haemoglobin are related to the blood.
"A chemical called nucleic acid" is wrong as it is not what DNA's made up of. DNA and RNA are nucleic acids themselves.
"An acid called chlorophyll" is wrong as chlorophyll is related to plants.
Which dance resulted from the development of a culture technique for muscle cells
Rhythm Salsa resulted from the development of a muscle cell culture technique.
How to do cell culture?To obtain a cell culture, it is necessary to disaggregate the original tissue, which can be by mechanical force or enzymatic process. These cells are grown in an adherent layer in a single layer (monolayer) or in organoid format (3D culture) or in suspension.
