which polymer is responsible for inharetence
The polymer responsible for inheritance is DNA in cells. It transmits genetic information from one generation to another. The functionality of different polymerases, including RNA polymerase, can be observed in experiments involving α-amanitin, a mushroom-produced toxin.
Explanation:The polymer responsible for inheritance is known as DNA (DeoxyriboNucleic Acid). DNA, which is located in the cell nucleus, is responsible for the transmission of genetic information from one generation to the next. It consists of two twisted strands forming a double helix. Each strand is a polymer composed of repeating units called nucleotides.
The transfer of genetic information involves specific polymerases including RNA polymerase. A demonstration of this process can be witnessed in gene expression experiments involving α-amanitin, an oligopeptide toxin produced by certain mushrooms. Intriguingly, the α-amanitin impacts different polymerases in various ways. For example, RNA polymerase I is completely affected by it.

Approximately how much water is reabsorbed into the blood after filtration out of the blood in the renal corpuscles of the kidneys
The percentage of water reabsorbed into the blood after filtration out of the blood in the renal corpuscles of the kidney is 99%. In tubular reabsorption, the percentage of 1% of the glomerular filtrate actually leaves because the 99% is reabsorbed into the blood when it passes in the renal tubules and ducts. This process is tubular reabsorption and occurs in three mechanisms which are osmosis, diffusion and active transport. The body’s needs are the basis why reabsorption varies as per individual. This enables the body to retain most of its nutrients. This happens when solutes and water are removed from the tubular fluid and transported into the blood.

Hydroxide is not a suitable base for deprotonation of acetylene:
Hydroxide is not a suitable base to deprotonate acetylene because acetylene is a weak acid with a high pKa, and OH− is not strong enough to shift the equilibrium towards the deprotonated species. Stronger bases like NH2− are required for effective deprotonation.
The student's question revolves around why hydroxide (OH−) is not an appropriate base for the deprotonation of acetylene (HC=CH). In chemical terms, acetylene possesses acidic protons but is still a relatively weak acid, with a pKa value of about 25. While hydroxide is generally recognized as a strong base, it is not sufficiently strong to deprotonate acetylene effectively. The equilibrium of the reaction between hydroxide and acetylene lies significantly to the left, indicating that the reaction does not favor the formation of the deprotonated product. Stronger bases, such as amides (NH2−), are necessary to successfully remove a proton from acetylene.
Furthermore, comparing the acidities of different molecules, it has been observed that in aqueous solution, the acidity of alkynes is not well-characterized but is presumed to be around 1010 times less acidic than water. However, in the gas phase, ethyne (another name for acetylene) behaves as a stronger acid than water. This exemplifies how the environment can influence acid-base behavior.

You notice that after you sprained your ankle that the ankle become swollen, red, and hot. why did the ankle get hot?
After a sprain, the ankle gets hot due to inflammation caused by increased blood flow to the affected area.
Explanation:The ankle gets hot after a sprain due to the process of inflammation. When there is an injury, such as a sprained ankle, histamine is released, causing increased blood supply to the affected area. This increased blood flow leads to redness, swelling, and heat. The heat is a result of the increased metabolism and activity of immune cells in the area.
Rest and Elevation:
Resting the injured area and elevating it above the level of the heart can help reduce inflammation by promoting proper fluid drainage.
Cold Compress:
Applying a cold compress or ice pack can also be effective in reducing inflammation and providing relief. This constricts blood vessels, which can help minimize swelling.
Medical Evaluation:
While initial care can be administered at home, it's important to seek professional medical attention for a thorough assessment, especially if the pain, swelling, or other symptoms persist or worsen.

As a result of its involvement in a reaction, an enzyme remains unchanged and unaltered.
As a result of its involvement in a reaction, an enzyme remains unchanged and unaltered. Enzymes are biological catalysts that speed up chemical reactions by reducing the activation energy required for the reaction to occur. Enzymes facilitate the conversion of substrates into products without themselves undergoing any permanent changes. They do not get consumed or depleted during the reaction.
Enzymes achieve this by binding to substrates, stabilizing the transition state, and facilitating the formation or breaking of chemical bonds. After the reaction, enzymes are released and available for further catalytic cycles, making them highly efficient and crucial components of metabolic pathways, ensuring the proper functioning of various biochemical processes in cells.

How do webbed feet help ducks survive? Webbed feet help ducks maintain homeostasis. Webbed feet help ducks move efficiently through water. Ducks are birds, and many birds have webbed feet. Webbed feet help ducks keep their balance on land.
Webbed feet in ducks are specialized features that help them move efficiently through water, aiding in swimming and floating. This adaptation allows ducks to easily find food, evade predators, and migrate. The primary function of webbed feet is to facilitate movement in aquatic environments.
Explanation:Webbed feet are a specialized adaptation that help ducks move efficiently through water. The webbing between their toes allows them to paddle and navigate in water, acting almost like a boat's oar. This efficiently propels them forward, making them excellent swimmers. Ducks spend a significant portion of their lives in aquatic environments, where having webbed feet offers a considerable survival advantage. It enables them to easily pursue prey, escape predators, and move swiftly to different locations in search of food or during migration.
Besides aiding in swimming, webbed feet also support ducks floating on water surfaces. This feature, combined with their ability to fly, provides a significant advantage in avoiding terrestrial predators. Therefore, webbed feet are critical for ducks' survival, directly affecting their ability to find food, avoid danger, and ultimately reproduce. However, it's important to note that while webbed feet assist in aquatic environments, they are not primarily for keeping balance on land or maintaining homeostasis; their main function is to aid in movement through water.
