The way that looking at the carbon footprint or water footprint similar to looking at a biomass, energy, or numbers pyramid is that indicates how much energy is stored as new biomass at each trophic level, and a pyramid of biomass shows how much biomass is stored as new biomass overall.
What is the carbon footprint of biomass?Of all energy sources, biomass energy has the fourth-highest carbon footprint. On a life-cycle basis, biomass fuel emits 230 grams of carbon dioxide (CO2) for every kWh produced. It is not as advantageous as it might seem, it contributes to climate change, and has other detrimental environmental repercussions.
Therefore, note that at higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic level creatures is known as biomass.

Explain why catalase works differently in different conditions. Give specific examples
and relate your answer to the structure of proteins.
Like many enzymes, catalase has effects that are regulated by the temperature of the environment. The structure of catalase and the hydrogen bonds it is intended to break are both impacted by temperature. The hydrogen bonds between molecules of hydrogen peroxide relax as temperature rises toward the optimal point, facilitating catalase's reaction with the molecules. The enzyme denatures and its structure is upset if the temperature rises above the ideal level.
For example, The ideal temperature for catalase in human is 37 degrees Celsius.
What is catalase?
Hydrogen peroxide is broken down into water and oxygen by the common enzyme catalase, which is present in almost all living things exposed to oxygen. It is a crucial enzyme for defending the cell against reactive oxygen species' oxidative damage.
Hence the correct answer is given.

Which human activity would decrease the biodiversity of a wetland¹?
Answer:
a is the correct answer Human uses of wetlands, such as drainage for agriculture and filling for industrial or residential development, can impose irreversible impacts to wetlands.
The human activity that would decrease the biodiversity of a wetland is adding a drainage system. The correct option is 1.
What is biodiversity?Biodiversity refers to the diversity of life on Earth, which includes species diversity, genetic diversity, and ecosystem diversity.
It is critical for ecosystem health and function, as well as the services they provide, such as air and water purification, nutrient cycling, and climate regulation. Biodiversity has cultural, recreational, and economic significance.
The extinction of species, the loss of genetic resources, and disruptions to ecosystem services are all examples of how biodiversity loss can harm ecosystems and human well-being.
Adding a drainage system would reduce a wetland's biodiversity by altering the natural water flow and affecting the habitat of various species, resulting in a decrease in their population and diversity.
Thus, the correct option is 1.

Materials move down a concentration gradient is called a concentration gradient and the methods cells use to materials with out expanding energy is called Passive transport.
How can you move substances down the concentration gradient without using energy?Passive transport tells more about the shifting of substances down a concentration gradient and does not need any issue of energy consumption.
A concentration gradient is simply a stretch of space across which a substance's concentration alters. Substances will naturally travel down concentration gradients, from a higher concentration point to a place or area that is known to be lower concentration area.
Therefore, substance diffuses over a membrane through passive transport as it diffuses along its concentration gradient without requiring any energy from the cell.

What causes cells to stop growing?
According to research coauthor and geneticist at Harvard Medical School Stephen Elledge, cell death — the stopping of cells from growing and dividing — is caused by extreme stress and genetic damage.Specifically because to water pressure, plant cells maintain their form.Water is actively pumped into plant cells to maintain their rigidity.The cellulose and pectin-based cell wall's durability prevents the cells from bursting under pressure.All living cells need a little chemical known as adenosine triphosphate (ATP) as fuel, which is one of the earliest and most persistent lessons that students learn in biology class. Numerous genes play a role in regulating cell division and development.The cell cycle is the orderly, sequential process by which a cell duplicates itself.This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes.Checkpoints, also known as restriction points, are locations in the cell cycle when specific genes can check for issues and stop the cycle for repairs if something is wrong. A cell may self-destruct if there is a DNA mistake that cannot be corrected (apoptosis).Apoptosis is a process that occurs frequently throughout life to help the body get rid of cells that are no longer functional or that are unnecessary.A type of white blood cell known as a macrophage dissects and recycles cells that have undergone apoptosis.Apoptosis plays a critical function in the development of the embryo and the maintenance of adult tissues, as well as protecting the body by eliminating genetically compromised cells that could cause cancer. Diseases like cancer can result from an alteration in the cell cycle's regular regulation.Cells can divide randomly and collect genetic mistakes that can result in a malignant tumor when the cell cycle is out of control.To learn about cells refer

Which statement best describes an environmental consequence of sustainable waste management?
This can be as simple as providing recycling and compost bins along with your regular trash and offering a service to properly dispose of this waste.
Poor waste management contributes to climate change and air pollution, directly affecting many ecosystems and species. Considered the last resort in the waste hierarchy, landfills release methane, a very potent greenhouse gas linked to climate change.
Sustainable waste management is important. This enables continued socio-economic development and protects the environment and health. It paves the way for developments that meet today's needs without jeopardizing the development of future generations. One of the first causes of poor waste management is lack of public awareness, and more specifically, lack of awareness and bad attitudes within companies.

The distance used to determine the work is less.
What is work done?When an external force drives an object a specific distance, it transfers a certain amount of energy to the object, which is known as work. The amount of work performed on an object is a measure of the energy transmitted to it. Work is defined as the sum of the force component acting in the displacement direction and the displacement magnitude (d).
A measurement of the energy that is transferred when an object is moved over a distance by an external force, at least some of which is applied in the direction of the displacement.
The output of a force is calculated by multiplying its component acting in the displacement's direction by its magnitude.
