A bird species in danger of extinction has a population that is decreasing exponentially left parenthesis upper a equals upper a
serious [3.7K]

Answer:

This will happen in 39 years.

Explanation:

The population of the birds varies as A = A.e^kt

The population of birds fell from 1400 from 1000

Time it will take for the population to fall below 100 = x years.

when t = 0, population = 1400

t= 3; Population = 1000

Therefore:

1400 = 1000e^5k

e^5k= 1400/1000

k= (In 1.4)/5

we need to find x, such that

1400/1000= (e^xk)

14=(e^xk)

In(14) =kx

x= 5In(14)/In(1.4)

x= 39 years

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some
xz_007 [3.2K]
The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".

Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.
