Why is Formalin used for preserving biological specimens?
Formalin is used for preserving biological specimens because it prevents the decomposition and decay of tissues by inhibiting the growth of microorganisms and enzymes. It fixes the tissues by forming cross-links between proteins, helping to maintain their structure and morphology over time. This preservation method allows researchers to study specimens for longer periods and observe specific characteristics under a microscope.
When a piece of zucchini is soaked in saltwater the zucchini breaks down and loses its firmness. Which best explains what happens to the zucchini?
The process is osmosis, where water moves from an area of lower solute concentration (inside the zucchini) to an area of higher solute concentration (the saltwater solution). This results in water leaving the zucchini cells, causing them to shrink and lose their firmness.
Why is Luke Burke such a dick?
I can't comment on specific individuals. Remember, each person is complex and has a unique perspective. It's important to try to understand someone's behavior by considering their experiences and motivations, rather than jumping to negative conclusions.
How might a lower than normal fibroblast cell population affect an individuals skin?
A lower than normal fibroblast cell population can lead to impaired skin healing and regeneration, as these cells are essential for producing collagen and supporting the structural integrity of the skin. This can result in delayed wound healing, increased susceptibility to infections, and compromised skin elasticity and firmness.
Why did scientists question Avery's findings?
Scientists questioned Avery's findings because they had difficulty accepting that DNA, which was previously thought to be a simple molecule, could be responsible for genetic inheritance. Additionally, Avery's experiments were considered too simple and lacked detailed mechanistic explanations to convince some scientists of his conclusions.
What is firmness?
I think because of breasts
What is the hardness of polonium?
Data about the hardness of polonium don't exist.
Why hardness is a intensive?
Because the hardness is not dependent to the size of a material sample.

What is the difference between vickers hardness test and brinell hardness test?
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
Is there any fundamental unit associated with Rockwell Hardness Test?
No, because hardness is not a fundamental quality
What is the hardness of krypton?
The hardness of krypton is not typically measured because it is a colorless, odorless, and tasteless gas at room temperature. Hardness is a property that typically applies to solid materials.
Why is the hardness of a mineral important?
The hardness of a mineral is important because it helps in mineral identification. Minerals with different hardness values can be distinguished using the Mohs hardness scale. Hardness can also indicate the durability and wear resistance of a mineral in various applications.
What is Moh's hardness for H Hydrogen?
Hydrogen does not have a specific Mohs hardness because it is a gas and does not typically form solid minerals that can be tested for hardness using the Mohs scale.
Why is formaldehyde or formalin used in formol titration procedure?
Formaldehyde or formalin is used in formol titration procedure as a titrant because it reacts with the substances being titrated and forms a colored complex that can be easily detected. This complex formation allows for a precise determination of the concentration of the analyte in the sample being tested.
What hardness does a mineral have if it scratched by glass but scratched an iron nail?
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
What is hardness sometimes referred to as scratch-ability?
Hardness is sometimes referred to as scratch-ability because it measures a material's resistance to scratches or abrasions. Materials with higher hardness are less likely to get scratched easily compared to materials with lower hardness.
