Polarity is defined as the separation of electric charge in a molecule or having an electric dipole moment due to the difference between negative and positively charged ends.
In the given experiment when one milliliter of the substance into a beaker is filled halfway with water, the substance will be seen as coagulating or not dissolving in the water.
The non-polar are the compounds or liquids that do not dissolve in the water. The non-polar molecules are the molecules, which are attracted to the alike molecules, rather than the water molecules.
The non-polar compounds have covalent bonds, in which the electrons are shared among the atoms of the compound.
The molecules of these liquids are repelled in the presence of water or are hydrophobic. These liquids do not dissolve in water.
Therefore, the liquid is hydrophobic.
To know more about the polarity, refer to the following link:
Answer:
Explanation:
Non-polar liquids are liquids that have covalent bonds in which the shared electrons are shared equally. The molecules of these liquids are repelled by the molecules of water and hence do not dissolve in water. Thus, non-polar liquid are hydrophobic (water dislike/insoluble in water).
When one milliliter of the substance is placed into a beaker filled halfway with water, the substance will be seen "compact" (not dissolving nor interacting) in the beaker of water.
Answer: The biosafety level required for a microbiology laboratory working with potentially airborne pathogens such as tuberculosis bacteria is Biosafety Level 3 (BSL-3).
Explanation:
BSL-3 laboratories are designed to handle microorganisms that can cause serious or potentially lethal infections through inhalation. Here are some key features and practices typically found in BSL-3 laboratories:
1. Facility design: BSL-3 laboratories have specialized engineering controls to prevent the release of airborne pathogens. These controls include directional airflow systems that ensure air flows from clean areas to potentially contaminated areas, preventing the escape of pathogens into the environment.
2. Personal protective equipment (PPE): Personnel working in BSL-3 labs must wear appropriate PPE, including respiratory protection such as N95 masks or powered air-purifying respirators (PAPRs) to prevent inhalation of infectious aerosols.
3. Containment equipment: BSL-3 labs have specialized containment equipment, such as biological safety cabinets (BSCs), that provide an additional physical barrier between the personnel and the infectious agents. BSCs use high-efficiency particulate air (HEPA) filters to trap and remove infectious particles from the air.
4. Training and protocols: Personnel working in BSL-3 labs receive extensive training on handling potentially infectious materials and following strict protocols to minimize the risk of exposure. This includes proper decontamination procedures, waste disposal, and disinfection practices.
5. Access control: Access to BSL-3 laboratories is restricted to authorized personnel who have undergone appropriate training and are familiar with the specific safety requirements.
In summary, a BSL-3 biosafety level is required for microbiology laboratories working with potentially airborne pathogens like tuberculosis bacteria. These laboratories have specialized infrastructure, equipment, and protocols in place to protect personnel and prevent the release of infectious agents into the environment.

Answer
Gas exchange is the delivery of oxygen from the lungs to the bloodstream
Explanation:
It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
write it in your own words, also can i have brainliest
Answer:
XD....
Explanation:
Gas exchange is the physical process by which gases move passively by diffusion across a surface.
If 5 cell organelles could talk, they might say: Nucleus - I'm the brain of the cell. Without me, things would be a mess! Mitochondria - I provide the energy that keeps the cell going. Call me the powerhouse! Ribosomes - We're the protein builders. Just call us the construction crew! Lysosomes - We're the cell's waste disposal team. We clean up the mess! Endoplasmic Reticulum - We're the transportation system of the cell. We make sure things get to where they need to go!
