Inside a bacteria

The bacteria species has

• Thin peptidoglycan

• Chitin in its cell wall

• Lipopolysaccharide outside its cell wall

• Teichoic acid

For water uptake, a bacterial cell can do .... transport that works due to concentration gradient

Reason why a bacterial cell can be differentiated from a yeast cell based on their ribosome

Bacillus anthracis can produce endospore

• to reproduce

• as part of defence mechanism

• that can be destroy easily using pasteurisation

• that is dangerous even without germination

Lipid bilayer in a bacterium's cytoplasmic membrane

• has non-polar fatty acid head that is hydrophobic

• has polar fatty acid tail that is hydrophobic

• has non-polar fatty acid tail that is hydrophilic

• has polar fatty acid head that are hydrophobic

Streptomycin and gentamycin are antibiotics that work specifically on bacteria due to their effects to peptidoglycan

• True

• False

Nucleus can be found in

• Only in Gram-positive bacteria

• Both Gram-positive and Gram-negative bacteria

• A yeast's cell

• A virus's cell

Why bacterial plasmid is often used in genetic engineering for carrying some genetic materials and for other genetic manipulation process?

Oxygen uptake by an aerobic bacteria species can be considered as passive transport because it does not require

Lipopolysaccharides

• Can be found in Gram-negative bacteria and has chitin and sterol as its main contents

• Has positive-charge and can be found in Gram-negative bacteria

• Can be found in spore-former Gram-negative bacteria only

• Can be found in all Gram-negative bacteria
