The shape of the active site in a given enzyme is determined by the amino acid residues of the protein and the interaction between such amino acids and also molecules in the physiological conditions of the surrounding media.

The active site in a given enzyme protein is the molecular domain in the enzyme that binds to the substrate in a chemical reaction in order to form the enzyme-substrate complex that will be converted into products. The shape of the active site in the protein enzyme also depends on the amino acids in the domain that binds to the substrate and also to the molecular interactions.

Therefore, with this data, we can see that the active site in a given enzyme protein is dependent on the amino acids in the protein and their interactions.

Explanation:

A protective thrombus plus callus are formed around a fracture shortly after it occurs as a result of the body's protective measures to treat the wound. On both sides of a fracture line, fresh bone cell "threads" start to form.

The cells that compose bone tissue are known as bone cells. A highly specialized tissue called bone serves three major purposes: to protect internal organs, to provide a solid framework for muscular activity, and also to store minerals like calcium and phosphorus.

The growing parts of bone, such as the periosteum and endosteum, include osteoblasts, the bone cells in charge of creating new bone. Osteoblasts, that don't divide, produce and secrete calcium salts and the collagen matrix.

Explanation:

Bacteria: are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles.

Fungi: are eukaryotes that are characterized by the presence of chitin in the cell wall.

Cell Type: All bacteria are prokaryotes. All fungi are eukaryotes.

To summarize: arteries and veins differ in terms of their structure, direction of blood flow, presence of valves, oxygenation, blood pressure, blood volume, and appearance. Arteries carry oxygenated blood away from the heart, have thicker walls, higher pressure, and no valves, while veins carry deoxygenated blood towards the heart, have thinner walls, lower pressure, and contain valves to ensure one-way blood flow.

Answer: A diverse population of bacteria that is treated repeatedly with the same antibiotic and not all of them die will eventually lead to the emergence of antibiotic-resistant bacteria that will thrive and become dominant. The population's antibiotic resistance level before being exposed to the antibiotic was low or non-existent. The "good" bacteria will die while the antibiotic-resistant bacteria will survive and reproduce. After antibiotic treatment, the population's antibiotic resistance level will be higher than before.

Explanation:

ecosystem be altered without the actions of decomposers and Dead matter would build up, and all populations would eventually decrease.

Animal corpses, human waste, and dead plant components like leaf litter and timber are all consumed by decomposers. They perform a vital role as Earth's cleanup crew. If decomposers didn't exist, dead insects, dead animals, and dead leaves would pile everywhere. More significantly, decomposers give plants and algae, which are often the main producers in an ecosystem, vital nutrients. Decomposers break down complex organic materials into less complicated compounds that also contain water and carbon dioxide, calcium, nitrogen, and phosphorus. Each of these components is necessary for plants to flourish.

Answer:

Unicellular and multicellular organisms reproduce to ensure the continuation of their species and the survival of their genetic information over time. Reproduction is a fundamental biological process that allows organisms to pass on their genes to the next generation, ensuring the perpetuation of their genetic information and the maintenance of genetic diversity within a population.

Explanation:

For unicellular organisms, reproduction is the primary means of propagation and growth of the species. They reproduce asexually through binary fission, budding, or other forms of cell division, where a single cell divides into two identical or nearly identical daughter cells.

For multicellular organisms, reproduction involves the fusion of gametes (sperm and egg cells) to form a zygote, which then develops into a new organism. Sexual reproduction allows for the mixing of genetic material from two parents, resulting in genetic diversity in the offspring and enhancing the adaptability of the species to changing environmental conditions.

In addition to ensuring the survival of the species, reproduction also allows for the repair and replacement of damaged or lost tissues in multicellular organisms. Many tissues and organs in the body are capable of regenerating or producing new cells through mitosis or other forms of cell division, allowing for growth and repair over time.

Overall, reproduction is essential for the survival and evolution of both unicellular and multicellular organisms, allowing them to adapt to changing environmental conditions and ensure the continuation of their genetic information over time.

The procurement of Henrietta Lacks cells brings up many issues including informed consent, medical records privacy, and communication with tissue donors and research participants.

Black lady Henrietta Lacks was a 31-year-old mother of five who passed away from cervical cancer in 1951. She leaves a stunning legacy of ever reproducing cells that have effectively attained "immortality," carrying her name and memories with them. In laboratories all across the world, her cancerous cells have survived long after she passed away and have multiplied so rapidly that if put end to end, they could wrap the globe three times.

Little did Henrietta know when she went to a cancer clinic at Johns Hopkins in Baltimore in January 1951—the only hospital in the region at the time that treated African Americans—that she would eventually reach a type of immortality.

Without her consent or knowledge, her surgeon, Howard Jones, removed a tissue sample from her diseased womb. This sample was sent to George Otto Gey, a doctor and cancer researcher at the same Baltimore hospital, who was astounded by the cells' capacity to proliferate in lab culture.

Therefore, the procurement of her cells brings up many issues including informed consent, medical records privacy, and communication with tissue donors and research participants.

Answer:

The CFTR behaves like a channel for chlorine. Its dysfunction affects both the transport of this ion and other ions and the transport of water, which causes a thickening of secretions, an alteration of mucociliary transport and local defenses, facilitating bacterial colonization and promoting the release of pro-inflammatory mediators in the airway

Explanation:

CFTR is a protein expressed in the epithelial cells of the respiratory system, pancreas, bile ducts, sweat glands and genitourinary system. It is made up of a single chain made up of 1,480 amino acids. It contains 12 hydrophobic regions embedded in the lipid membrane and acts as a channel for chlorine.The highest levels of expression of the CFTR protein are found in serous cells of the submucosal glands of the proximal airway. In them, Cl- is released to the outside. In addition, there are channels for Na +, through which this ion is also secreted in the same direction. These movements cause the displacement of water and also of mucins, originating in the submucosal glands, allowing their presence on the surface of the airway. For all this to occur normally, a basolateral Na + - K + - ATPase cotransporter must function, another basolateral cotransporter formed by Na +, K + and 2 Cl-, which allows the latter to enter the cell, and an apical CFTR channel through which it exits the Cl- of the cell towards the acinar lumen. Na + leaves the cell following Cl- by a paracellular pathway accompanied by water. When CFTR malfunctions, Cl- does not exit through this channel and this implies a decrease in Na + and water in the canalicular lumen, with the consequent thickening of secretions.

If some mice have inherited a genetic mutation that causes them to have a band of white fur around the middle of their bodies, it is most likely that an ancestor of these mice also had the same genetic mutation that caused the band of white fur.

Genetic mutations are changes in DNA sequence that can be inherited by offspring from their parents. If a mutation passed down from the parent to its offspring, then next generations will also have the same mutations. The white fur band presence suggests that the mutation for this trait has been inherited through multiple generations of mice.
