The antibiotic called ampicillin was not effective against E.coli.
Answer: D
Explanation:
E.coli is normal microbial flora which is present in the gut of the mammals.
It is gram negative bacteria and very few strains of this bacteria causes harm.
Antibiotics are the chemical drugs which are used to treat the microbial infection either by killing the causative organism or by its growth inhibition.
Antibiotics such as neomycin, penicillin and erythromycin are usually used to treat E.coli infection.
Antibiotic such as Ampicillin is not used as the bacterium E.coli is highly resistant to it.
I think the correct answer from the choices listed above is option B. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will <span>stop moving across the membrane. This is because equilibrium has already been achieved and there is no more driving force which is the concentration gradient present.</span>
Answer:
c. autotrophs and animals are heterotrophs
Explanation:
There's many differences between the plants and the animals, be it their physical appearance, way of live, how do they function, their requirements for survival. One of the major differences between the plants and the animals is that the plants are autrotrophs, while the animals are heterotrophs. The autrophs are the organisms that are able to produce their own food, thus they are producers, meaning that they do not need nutrition from other organic sources. The heterotrophs on the other side are the organisms that are not able to produce food for themselves, but instead they get their food through consuming of other living organisms, making them primary, secondary, and tertiary consumers.
