Answer:
The metabolic capacities should be:
Bacteria that fulfill replicative cycles, have a metabolization that requires a substrate or a metabolite, coexist in extreme environments where their method of survival is sporulation.
Ability to admit genetic mutations between different bacterial colonies for their possible evolution, an ideal environment with pH, gases, and substrates according to the life of the bacterial colony, which is often called as a culture medium.
Explanation:
Temperature is essential in bacterial growth, as is the pressure and environment that surrounds the bacteria.
Something that must be taken into account is that other microorganisms coexist with the bacteria in the medium, since they can be limited to their colonization, an example of this is the gram negative and positive bacteria, coccoid and bacilloid, which generally are not compatible with the penicillium fungus, as this, as a product of its metabolization, releases a substance called penicillin that prevents the colonizing growth of other species of microorganisms such as this type of bacteria.
D). Beliefs are not scientific.
The answer is <span>-Only the few bacteria that were immune to the antibiotic survived and reproduced, making all their offspring immune to it as well.
Bacteria (or any other organism) are not able to make changes to their DNA in order to protect themselves or to learn to remove the receptors on their cell surfaces. If they were able to produce toxins against the antibiotics, they would all survive.
These leave the second choice as the correct answer. This is the real situation, and is a good example of natural selection.</span>
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.
