D. a niche is an organisms "job"
Answer:
The correct answer id A. An area of no growth immediately around the application of substance called the "zone of inhibition" with the greater the zone size the greater the effect on the bacteria, ie the reduction or inhibition of growth.
Explanation:
When the effect of any antibiotic, antiseptic or disinfectant is to be checked then the substance is applied on some spots on agar plate and then spread plate culture technique is performed under aseptic technique.
Then after some hours of incubation area with bacterial growth and area without bacterial growth can be seen on the agar plate. The area where no bacterial growth occurs is called the zone of inhibition.
More the zone of inhibition produced by the substance more will be its effectiveness against the bacteria that means it can inhibit the growth of more bacteria. So, the right answer is A.
Answer:
(a) Symbiotic, as both benefit each other for food
Explanation:
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.
Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp. The nearly blind shrimp and the fish spend most of their time together. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone. From their relationship, the shrimp gets a warning of approaching danger. The fish gets a safe retreat and a place to lay its eggs.
Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a “free ride.” Hermit crabs use the shells of dead snails for homes.
Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. Many species of animals are parasites, at least during some stage of their life. Most species are also hosts to one or more parasites.
So. we can easily say that the relationship between them is symbiotic.
