Lactic acid fermentation can be modeled by which equation?
O Lactic acid + NADH → Pyruvic acid NADH
O Pyruvic acid + NAD+ → Lactic acid + NADH
O Lactic acid + NADH → Pyruvic acid + NAD+
O Pyruvic acid + NADH → Lactic acid + NAD+
Answers
Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+
LACTIC ACID FERMENTATION:
Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC. However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+. This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:Pyruvic acid + NADH → Lactic acid + NAD+Learn more at: https://brainly.com/question/11502989?referrer=searchResults
Answer to Question 1:
Well, given the choices to the question above 'Lactic acid fermentation can be modeled by which equation?', I would say that the best choice would be 'Pyruvic acid + NADH → Lactic acid + NAD+', or in other words, Option D.
Explanation for Question 1:
For a further explanation expanding more on the first question and showing why, the user above's answer is super helpful.
Answer to Question 2:
For the additional question asked 'In the Krebs cycle, how is citric acid formed?', I didn't see the options, however I believe they are:
O Carbon dioxide bonds with a chain of coenzyme A.
O Pyruvic acid molecules are broken down by an acetyl group.
O Acetyl-CoA joins with a large molecule called ozaloacetic acid.
O Enzymes combine hydrogen ions, oxygen, and electrons.
^ This being said, I would say your best choice would be Option C.
Explanation for Question 2:
The Krebs cycle begins when acetyl-CoA combines with a four-carbon molecule called OAA, aka oxaloacetate. This begins to produce citric acid, in which has six carbon-atoms. This is why the Krebs cycle is also referred to as 'the citric acid cycle.'

How does bromothymol blue act as an indicator for carbon dioxide? What evidence do you have to support your conclusion?
Answers
Answer:
Carbon dioxide production can be measured by breathing through a straw into a solution of bromothymol blue (BTB).
Explanation:
BTB is an acid indicator; when it reacts with acid it turns from blue to yellow. The more carbon dioxide you breathe into the BTB solution, the faster it will change color to yellow.

What are coral reefs?A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Coral reefs are massive structures made of limestone deposited by coral polyps. Often referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species.
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

Abstract -
The rapid increase of human population is putting an incredible strain on our environment. While developed countries continue to pollute the environment and deplete its resources, developing countries are under increasing pressure to compete economically and their industrial advancements are damaging as well. The demands that this growth places on our global environment are threatening the future of sustainable life on earth. One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate. Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water. The growth of population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems that must be addressed in order to ensure that life on earth will be sustainable throughout the next century.

The picture depicts a mangrove swamp within Florida Everglades. This means that the Everglades is most likely Estuary due to the presence of mangrove trees thriving in both freshwater and saltwater environments. The correct option is (B).
The picture shows a mangrove swamp in a section of the Florida Everglades. Mangroves are unusual trees that have the amazing capacity to thrive in both freshwater and saltwater environments. Estuaries, where rivers meet the sea and create a setting with variable salt levels, are notable for this adaptability.
The Florida Everglades is a perfect example of an estuary environment since the coexistence of mangroves in this ecosystem implies the presence of brackish water, which is a mixture of freshwater and seawater. Estuaries are key for maintaining a variety of wildlife and offering crucial ecological functions.

Does the amount of energy from the food eaten (Kcal) by each organism equal the amount of energy used by each organism? Support your answer by showing your calculations. (Show your work > math icon)
Answers
Answer:
Explanation:
This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.
