fatty acid oxidation: acetyl CoA is a product, takes place in the mitochondria, intermediates linked to coenzyme A, uses FAD and NAD+.
The majority of the chemical energy required to drive a cell's metabolic operations is produced by membrane-bound cell organelles called mitochondria (plural: mitochondrion). Adenosine triphosphate is a little molecule that stores the chemical energy generated by the mitochondria (ATP). Sugar is thought to be bad for our teeth and our waistlines, but it's also the enemy of our mitochondria and a major factor in many metabolic health problems. Extra sugar consumption stresses the mitochondria, forcing them to release free radicals. Oxidative damage is what this is.

Explanation:
Henry has a mutation in the gene that codes for a certain blood protein. however, these proteins function normally. what best explains how this is possible?
Silent mutations happen when a single DNA nucleotide change inside a gene's protein-coding region occurs without changing the order of amino acids that make up the gene's protein.
For instance As an illustration, AAA (which codes for the amino acid lysine, Lys) can change to AAG (which also codes for Lys). Gene variations, sometimes referred to as mutations, can occasionally prohibit one or more proteins from functioning correctly. A variation can make a protein malfunction or not be created at all by altering the gene's instructions for producing it.
Mutations are long-lasting alterations to a gene's DNA sequence. The form of the protein that is generated can be impacted by mutations. A protein's function is impacted by its shape, which may also have an impact on the observed attribute. DNA regulates how amino acids combine to form a particular protein in a call. The sequence of amino acids in a protein is determined by the order of BASES in a particular segment of DNA.

the ingestion of a large number of vibrio cholerae cells is necessary for infection. why is such a large concentration of bacteria needed?
Ingestion of large numbers of Vibrio cholerae cells is necessary for infection, due to the low gastric pH.
Vibrio cholerae is pathogenic to humans. These bacteria are very sensitive to acids because these bacteria cannot stand acids and heat. If someone eats food that contains bacteria as much as 102-104 cells/gram in food then someone with normal stomach acid will be infected by Vibrio. Normally, the stomach produces stomach acid making the degree of acidity (pH) of the stomach boil between 1.0-2.0
To kill bacteria or germs in food. Because generally, bacteria are very rare that can live at the pH that is owned by the stomach, which is a pH of around 0.8 - 1.5.
So, when someone is infected with Vibrio cholera, the stomach acid pH is low.

pyruvate enzyme that slows down the kreb cycle how does this affect the production of nadph in glycolysis and the kreb cycle ap biology
Pyruvate is an enzyme that plays a major role in both glycolysis and the Krebs Cycle. It helps to break down glucose into its component molecules, and is also involved in the production of NADPH, an important energy carrier.
Pyruvate is responsible for the oxidation of glucose and the production of pyruvate, which is then used to generate ATP and NADPH.
The role of pyruvate in the Krebs Cycle is to slow down the cycle. This is important because it allows for the metabolism of multiple molecules of glucose, which makes it possible for the body to create more ATP and NADPH. The slowing down of the Krebs Cycle also helps to prevent the buildup of metabolic byproducts, which could lead to disease.
In glycolysis, pyruvate is responsible for the conversion of glucose into pyruvate. This reaction is important for the production of NADPH. Since NADPH is required for the synthesis of fatty acids, the availability of NADPH is essential for cell growth and maintenance. Without the slow down of the Krebs Cycle, there would not be enough NADPH produced, and cells would suffer from an energy shortage.

A endangered species is one that, while not now in danger of becoming extinct, may do so in the not too distant future.
tiny populations in narrow geographic regions, migratory species, those requiring expansive or unique habitats, and species that are subject to human exploitation. Species that are in imminent risk of becoming extinct are referred to as endangered species. An ecosystem's keystone species contributes to its definition. Without its species diversity, the ecosystem would either no longer exist or would change significantly. A species that is in risk of going extinct is said to be endangered. This may result from human activity or natural factors like competition or predation (Introduced species, habitat loss and degradation, climate change, etc.). A species is considered to be "endangered" if it faces extinction in all or a substantial portion of its range. A species is considered "threatened" if it is likely to become extinct in the near future.

5. peter and rosemary grant studied beak size in finches during drought and post drought in the galapagos island. what was their finding about the selection of beak size?
The Grants found that the birds who survived the 1977 drought tended to have larger offspring with larger beaks. The subsequent generation saw an increase in larger-beaked finches as a result of this ecological adaptation.
The Grant research team discovered that although the number of finch had increased during the drought, the average size of their beaks had increased. The main reason for this was that during the drought, large seeds with thick husks were still readily accessible, but small seeds were exceedingly scarce. The Grants returned to Daphne Major in 1978 to investigate the effects of the drought on the offspring of the medium ground finches. They looked at the young and compared the size of their mandibles to that of the ancestors (before to the drought). It was found that the beaks of the offspring were 3-4% larger than those of the grandparents.

Joann repeatedly overfed the fish in the pond behind her house. The nitrates from the excess food contributed to an overgrowth of algae. To correct the problem, Joann added more plants to the pond. How will adding more plants help?
By adding more plants to the pond, Joann increased the rate of consumption of the excess nitrates. It would also replenish the dissolved oxygen in the water.
Fish food is rich in nitrates and phosphates. So by overfeeding, Joann increased the concentration of the nitrates and phosphates in the pond water, making it ideal for algal overgrowth.
Algae uses these nitrates and phosphates to break down the organic substances in the pond water consuming more and more dissolved oxygen. The amount of oxygen that is dissolved in the water, or the amount of oxygen that is available to living aquatic organisms, is measured by the term "dissolved oxygen" (DO).
This might suffocate the fish by creating oxygen scarcity, which would lead to their death.
Hence by adding more plants, Joann can ensure the excess nitrates added would be consumed by the new plant, limiting the nutritional supply of the algae.
