_______ are raised under sterile conditions to limit their exposure disease-causing microorganisms.
tight junction
gut microbiota gap junction
germ-free mice pathogen-free mice
blood brain barrier adhesion plaque
occludin
Answer:
- The blood brain barrier is a layer of cells lining the blood vessels within the brain, acting as a filter that controls the molecules that pass between the blood and the brain.
- An organism's gut microbiota is the collection of all the microorganisms (e.g. bacteria, phages, fungi) that live inside the digestive system of that individual.
- A gap junction is a type of intercellular protein connection between animal cells that prevents leakage of materials through the space between the cells.
- The transmembrane protein occludin is one of the component proteins of a tight junction.
- Germ-free mice lack all microorganisms in their digestive systems, a state achieved by delivering them through cesarean section and raising them in sterile incubators.
- Pathogen-free mice are raised under sterile conditions to limit their exposure disease-causing microorganisms.
Explanation:
The blood-brain barrier is a layer of cells made up of endothelial cells that act to limit the passage of substances from the bloodstream in a more selective manner than endothelial cells of capillaries located in other parts of the body. Gut microbiota can be defined as all the microorganisms (i.e., bacteria) inhabiting the mammalian gastrointestinal tract, which helps to ferment non-digestible substrates (e.g., dietary fibers). A gap junction is a class of cell junction that is formed between cells contacting each other which allows small molecules (e.g., water, ions, metabolites, microRNA sequences, etc) to pass through this intercellular communication. In vertebrate animals, cell junctions can be divided into 1-gap junctions (communication between cells), 2-tight junctions (occludin junctions), and 3-adherens junctions, hemidesmosomes and desmosomes (anchor junctions). Tight Junctions are composed of multiple proteins including transmembrane proteins such as occludin, tricellulin, junctional adhesion molecule (JAM), and one member of the claudin protein family. Germfree animals are research animals that have no microorganisms living in or on them, which are housed in controlled/isolated conditions to prevent any type of contamination. Finally, pathogen-free animals are research animals that are guaranteed to be free of particular pathogenic (harmful) microorganisms.

One of your classmates submits the post below which is a very informative post about criteria for safe food production during the manufacturing process. What is missing from this post? "I recently read that industrial food processing factories are required to undergo periodic inspections by the United States Department of Agriculture as well as by the Food and Drug Administration. For the USDA, these inspections are conducted by staff in the Food Safety and Inspection Service, or FSIS."A. Did not refer to the source of the information in the body of the postB. Did not state what s/he specifically learned from the sourceC. Did not provide a citation for the source of the information
Answer:
A. Did not refer to the source of the information in the body of the post
Explanation:
In the post written by his friend, we can see that he decided to write information about the periodic inspections carried out by the United States Department of Agriculture as well as by the Food and Drug Administration, because he read about these inspections somewhere. However, he forgot to show this place where he read this information, that is, he forgot to present the source where he got the information presented in the post. By presenting the source, it would make the post more trustworthy and relevant.

Part C: Take Notes In a separate location, take notes from the sources you have identified. The notes will provide details for your presentation. While taking notes from texts and websites, use these reading strategies. In the space provided, write four pieces of information that you intend to use in your presentation. im to lazy to write the notes
Answer:
I do that sometimes I take notes in a separate location so is this like for your math homework cuz I am good enough but I don't like it that much but I'm good at it and sources identify things that will the source is like a key a key like you can open and close the door with and you're opening the key with the source so it really really really really and wouldn't be a good thing to take notes wherever you go like if you were writing a book you would want the source and the emotion and everything you wanted to buy

A)Evaluating an experiment allows the investigator to find errors and make improvements.
B)Evaluating an experiment is not important or required.
C)Evaluating an experiment can change the prediction.
D)Evaluating an experiment can make it more confusing.
Answer:
The correct answer is - A) Evaluating an experiment allows the investigator to find errors and make improvements.
Explanation:
Evaluation is the process in any experiment that helps in improving the analysis and remove missing components and errors to get better results. It also checks if all the process is included and running properly without error.
One should constantly be evaluating his or her experiment. It includes assessing how the experiment is going as you carry it out, what could have been improved if it was to be carried out again and how can eliminate any erros.

¿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).
