If the half-life is 5 minutes, then 30 minutes is equivalent to 6 half-lives. So, after six successive half-lives, the 400 mg of the radioisotope would have a mass of 400(0.5)⁶ = 6.25 mg.
Thus, A would be the correct answer choice here.
Answer:
Honestly nothing much unless you consider them to keep populations low of over populated animals.
Explanation:
Strong legs and huge front claws are used for digging, and long, sticky tongues for extracting ants and termites from their tunnels. In addition to bugs, armadillos eat small vertebrates, plants, and some fruit, as well as the occassional carrion meal. Armadillos are the only mammals that have protective armor. The mammals are known to dig up insect larvae for food, and it's possible they will compete for such meals with resident animals such as skunks. Armadillos have also been known to raid the nests of various species and so could harm populations of ground-nesting birds such as quail.

Answer:
Eco-efficiency.
Explanation:
Eco-efficiency is the relationship that exists between the economic value of a good or service offered in the market, and the environmental impact that its production generates for the human ecosystem. Thus, the lower the environmental impact generated by said product, the higher its eco-efficiency rate.
The search for eco-efficiency of goods and services aims to preserve the environment, that is, to guarantee a natural environment suitable for human life, in conjunction with a normal production of goods and services.
