How can you tell the difference between male and female"?
The difference between male and female can be determined by physical characteristics such as reproductive organs, secondary sexual characteristics, and genetic makeup.
What is the difference between harmless microorganisms and pathogens?
Harmless microorganisms are typically not harmful to humans and may even provide benefits, such as aiding digestion. Pathogens, on the other hand, are microorganisms that can cause disease or infection in their host. Pathogens are often identified by their ability to disrupt normal bodily functions or trigger an immune response.
What is the difference between ovum and secondary oocyte?
An ovum is a mature female reproductive cell that has completed meiosis. A secondary oocyte is an intermediate stage in meiosis that occurs during ovulation and has not yet completed meiosis.
What is the difference between microorganisms and organisms?
Microorganisms are tiny organisms that can only be seen with a microscope, such as bacteria, viruses, and fungi. Organisms, on the other hand, refer to living beings that can be seen with the naked eye, including plants, animals, and humans. Essentially, all microorganisms are organisms, but not all organisms are microorganisms.
What is the difference between resident flora and transient flora?
