Answer:
The curve that most closely describes the mean tempretire of the fluid as a function of position along the tube.
Explanation:
Hello. Your question is presenting very confusing words, however, through the context of the question as a whole, it is possible to see that you are saying that the water that enters a circular tube has a lower temperature than the temperature presented by the surface of the tube . In this case, if you are going to present a graph about this, it is important that this graph presents a curve that shows the relationship between the average water temperature as a function of the position of the water along the tube. This graph will be similar to the graph shown in the attached figure below.

Are most mutations bad?
Answer:
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.
Explanation:
Answer:
It depends, not all mutations are bad.
Explanation:
Some mutations don't affect anything and remain coding for the same gene so it ends up being the same even if it wasn't mutated in the first place.

¿Cuál es el rol de la genética microbiana en el contexto de la Biología?
¿Qué aplicaciones tiene la Genética Microbiana hoy en día?
¿En qué consiste el protagonismo de la Genética microbiana en el devenir histórico de la Biología?
Answer:
- La genética microbiana ha sido fundamental para la comprensión de diferentes mecanismo genéticos y evolutivos
- Los microrganismos son ampliamente utilizados en medicina y procesos biotecnológicos
- La microbiología ha permitido descartar la teoría de la generación espontanea (anteriormente aceptada en biologia) como así también formular nuevas teorías (hoy en día ampliamente aceptadas por la comunidad científica)
Explanation:
La genética microbiana juega un papel fundamental en biología, ya que los organismos microscópicos (por ejemplo, bacterias) poseen características únicas para el estudio de mecanismos genético/moleculares tales como, por ejemplo, 1-un corto tiempo generacional y 2-la capacidad de manipulación de un número de organismos muy alto (N muestral) en un laboratorio. En consecuencia, los microrganismos permiten estudiar mecanismos genéticos y evolutivos con mayor grado de precisión y versatilidad al ser comparados con organismos pluricelulares. La microbiología ha permitido el desarrollo de técnicas esenciales en el campo de la biología molecular: la técnica de edición genómica CRISPR-Cas9 se basa en el sistema adaptativo que poseen ciertas bacterias para hacer frente a infecciones virales. La biotecnología microbiana ha permitido también desarrollar diferentes tipos de alimentos y procesos biotecnológicos (por ejemplo, la cerveza y ciertos productos lácteos requiere la utilización de microrganismos para llevar a cabo el proceso de fermentación). Por otra parte, mediante técnicas de recombinación genética podemos explotar las características de los microrganismos para producir a gran escala ciertos productos biotecnológicos y medicinales (por ejemplo, producir insulina para uso humano). La microbiología emergió en la segunda mitad del siglo XIX y desde entonces ha posibilitado el desarrollo de importantes avances para el tratamiento y cura de enfermedades infecciosas, como así también descartar teorías tales como la generación espontánea y generar nuevos conocimientos en el campo de la biología y la genética (por ejemplo, el descubrimiento que el ADN se replica de manera semiconservativa fue realizado utilizando cepas de E. coli).

Which of the following models describes the way in which DNA Replication occurs?
semiconservative
dispersive
random
conservative
Answer:
semiconservative
Explanation:
The semiconservative model of DNA replication states that only one DNA strand is used as template for the synthesis of the other new strands. In DNA replication, the DNA molecule is first unwind into a replication fork containing two single strands of DNA.
After unwinding, DNA polymerase synthesizes new complementary strands of DNA using each of the old strands. So in essence, the two DNA molecules after replication consists of one old and one new strand of DNA. This is basically the semi-conservative model of DNA replication.

A red blood cell has an intracellular concentration of 300 mOsM of nonpenetrating solute. What best describes a solution containing 100 mM NaCl and 150 mM urea relative to the red cell?
The solution is hypertonic to a solution containing 100 mM NaCl and 150 mM urea relative to red blood cell.
The term "hypertonic" refers to a solution that has a higher concentration of solutes compared to another solution. In this case, the solution containing 100 mM NaCl and 150 mM urea has a higher concentration of solutes than the intracellular concentration of the red blood cell, which is 300 mOsM of nonpenetrating solute.
The concept of tonicity is important in understanding how solutions affect cells. When a solution is hypertonic to a cell, it means that there is a greater osmotic pressure outside the cell than inside. In this specific scenario, the hypertonic solution has a higher concentration of solutes (NaCl and urea) than the red blood cell's internal nonpenetrating solute concentration.
As a result, water molecules will tend to move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell) in an attempt to equalize the concentration on both sides of the cell membrane. This movement of water out of the cell can lead to cell shrinkage or crenation, which occurs when the cell's volume decreases due to water loss.
In summary, the solution containing 100 mM NaCl and 150 mM urea is hypertonic to the red blood cell because it has a higher concentration of solutes than the cell's internal nonpenetrating solute concentration, leading to water movement out of the cell and potential cell shrinkage.
