Explanation:
The enzyme carbonic anhydrase is a protein that binds to two small molecules: water and carbon dioxide. By holding the two molecules in the proper position, the enzyme allows the two molecules to react to form a product, carbonic acid. The enzyme then releases the product and becomes available to catalyze the same reaction once again. How does carbonic anhydrase change the reaction between carbon dioxide and water?
Answer:
Chemical groups on the surface of the enzyme reduce the reaction's ... 100,000 carbon dioxide and water molecules into carbonic acid every second but ... What fraction of energy available in the chemical bonds of glucose actually ... The resulting three carbon molecule, lactic acid, builds up as a waste product inside cells.
The hydrolysis of carbon dioxide into carbonic acid or bicarbonate would not occur without carbonic anhydrase. Therefore, only 15% of the carbon dioxide produced by the body would be removed from the tissues by the blood.
What is the importance of carbonic anhydrase?At least 80% of the bicarbonate transported throughout the entire kidney occurs in the proximal tubule and is mediated by proton secretion.
Bicarbonate is created when carbon dioxide is hydrated by carbonic anhydrase and subsequently dissociates into hydrogen ions and bicarbonate.
As a result, they are categorized as metalloenzymes. The enzyme helps move carbon dioxide while preserving the acid-base equilibrium.
Therefore, Similar to other epithelial, carbonic anhydrase is widely distributed in renal tissue and works to catalyze the hydration-dehydration process of CO2.

Which option identifies the most likely testable question in the following scenario? Scientists breed a group of fruit flies. They record the wing type of two parent flies and their offspring. Both of the parents had “normal” wings, but only 75 percent of the 1,000 offspring has “normal” wings. The other 25 percent have “vestigial” wings. This data helps the scientist’s draw their conclusions. Are different wing types of flies heritable? OR Is wing type a sex linked trait?
Answer:The different type of wing is most likely heritable, but i'm not sure.

Which statement best represents how structure relates to function? a. Some insects live longer than others. b. Many tropical birds can be taught to speak. c. Great white sharks have sharp serrated teeth for tearing into their prey. d. horse's mane is often black.
Answer:
C. Great white sharks have sharp serrated teeth for tearing into their prey.
Explanation:
I took the quiz.
Adaptation is the evolutionary process that allows the natural selection of the species. Great sharks having sharp teeth for tearing into prey are structures related to functions. Thus, option c is correct.
What is adaptation?Adaptation has been defined as the mechanism by which biological species adjust themselves to the changes in the environment around them in an ecosystem. This leads to the evolution of the structures and functions.
The sharp teeth structures of the white shark allow them the function of catching their prey in the ocean ecosystem. These structures were adapted for the survival of the species and to catch food.
Therefore, option c. the sharp teeth of great white sharks are the adapted structures that allow them to catch prey.

Answer:
This question is incomplete
Explanation:
This question is incomplete. However, let's understand some terms
Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.

Below are the seven properties of water that make life possible on Earth. Describe five of these properties and provide an example of each: Hydrogen bonding, cohesion and adhesion, surface tension, heat of vaporization, specific heat, density, and universal solvent
Answer:
Properties of water are given below.
Explanation:
Hydrogen bonding is an important bond which occurs between two water molecules which make them sticky due to partial positive charge on hydrogen and partial negative charge on oxygen. Cohesion and adhesion occurs due to the attraction of partial positive and partial negative charges of hydrogen and oxygen atom. Density of water increases with the decrease in temperature and maximum at 4 degree Celsius and after further decrease in temperature, decrease in density occurs which is a unique property of water. water is a universal solvent because a large amount of solutes can be dissolved in it. Heat of vaporization refers to the amount of heat required to transform liquid into vapors.Water has a heat of vaporization about 40.65 kJ/mol.
