Chemical Properties can be observed only when substances in a sample of matter are changing into different substances.

"Moderate sperm seen non-motile" typically means that a moderate amount of sperm cells were observed in a sample, but they are not moving. This can indicate issues with fertility or reproduction. Further testing or consultation with a healthcare provider may be needed to determine the cause and explore potential treatments.
"The microscopic bacteria are abundant on my fingernail."

One common structure that can be observed in a sample is its crystal lattice structure. This can be visualized using techniques such as X-ray diffraction, which provides information on the arrangement of atoms within the sample. The crystal lattice structure is unique to each material and can help identify the sample based on its characteristic patterns.
A physical property can be observed without changing the sample. Chemical properties requires you to change the sample.
The number and variety of colonies observed on the plates can provide insights into the diversity and abundance of microorganisms present in the sample. A higher number of colonies indicates a more diverse microbial community, while different colony morphologies suggest the presence of multiple bacterial species with unique characteristics. Variation in colony size, shape, color, and texture can also indicate different types of microorganisms present in the sample.
