Is penecillin a bacterium<br> true<br> false

Digiron [165]

Answer:

false

Explanation:

Penicillin prevents peptidoglycan from cross-linking properly in the last stages of bacterial cell wall synthesis. This greatly weakens the cell wall and causes the bacterium to lyse, or burst open, because of osmotic pressure. Penicillin is bactericidal because it directly kills bacteria.

Roundworms are what type of biohazard?

BlackZzzverrR [31]

Roundworms can be included in the Virus/parasite biohazard category

A biohazard is a biological substance that is dangerous to the health of living organisms (especially humans) and/or the environment.

Biohazards include different harmful microorganisms (e.g., bacteria), viruses, biological toxins, fungi, parasitic worms, etc.

Biohazards also include biological vectors that transmit diseases (e.g., mosquitoes, ticks, rodents, etc).

Roundworms are small organisms (nematodes) that may infect dogs and cats. Animals become infected when they ingest eggs that contain infective larvae.

These small organisms (roundworms) can live in the digestive tract (i.e., intestines) and cause health problems including, among others, abdominal pain, fever, diarrhea, etc.
