C. Ecosystem
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>
Translucent objects allow some light to travel through them. Materials like frosted glass and some plastics are called translucent.
A. As organisms use certain traits more frequently, each organism evolves overtime. Based of the theory of evolution by natural selection, organisms possess traits that have been inherited which enable them to better adapt to their environments. They are more likely to survive, reproduce, and pass on genes to their offspring.
I think the answer is A. The mutation only increase one ability of the bacteria so it can not make a new species. And the mutation is good for the bacterial to survival so it will increase its relative frequency. The bacterial has various food supply. The word extinct is not correct.
Answer:
over time the antibiotic will become less effective against bacteria.
Explanation:
A new antibiotic can kill a greater percentage of bacteria because very less bacteria is resistant towards that antibiotic but when that antibiotic is used continuously for a long time then some bacteria develop resistance against that antibiotic and due to natural selection these bacteria are selected.
So if a particular antibiotic kills 99% of a bacterial population so the continuous use of this antibiotic will allow some bacteria to evolve resistance against it. Then these resistant bacteria will be selected by natural selection and over time the antibiotic will become less effective against bacteria.
