A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample before treatment. After each day of treatment, 40% of the sample remains alive. Which best describes the graph of the function that represents the number of live bacteria after x days of treatment?A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0

B. f(x) = 5000(0.6)x, with a vertical asymptote of x = 0

C. f(x) = 5000(1.4)x, with a horizontal asymptote of y = 0

D. f(x) = 5000(1.6)x, with a vertical asymptote of x = 0

Answers

"f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0" is the one among the following choices given in the question that best describes the graph of the function that represents the number of live bacteria after x days of treatment. The correct option among all the options that are given in the question is the first option or option "A".

Answer:

The correct option is A.

Step by step explanation:

The exponential function is defined as

$f(x)=ab^x$

Where, a is initial value and b is growth factor or decay factor.

The initial population of bacteria is 5000.

After each day of treatment, 40% of the sample remains alive. It means the growth factor or decay factor is

$(40)/(100)=0.4$

Therefore the required function is

$f(x)=5000(0.4)^x$

The horizontal asymptote is y=0 because

$f(x)\rightarrow 0\text{ as }x\rightarrow\infty$

Therefore option A is correct.

What type of bird has a specialized beak for eating insects?a. hawk
b. buzzard
c. falcon
d. robin

Answers

Answer:

Robin.

Explanation:

Robin is a small bird that are generally found that were earlier classified in the thrush family. These birds generally have orange or red breast. The male and female species are same in color.

These birds are insectivorous and feeds on insects. They have special size beak for eating the insect. The beaks are modified especially for their eating habitats.

Thus, the correct answer is option (d).

You can simply figure this out through the process of elimination.
Hawk's, buzzard's and falcon's all are carnivores, eating snakes and similar small animals, however a Robin feeds on insects because of its small size.

Knowing this you can rule out A, B and C and thus the answer being D, robin.

How does meiosis help to maintain the continuation of a species?

Answers

Meiosis is the reproduction of cells that don't exchange DNA, its important because if you have a cut on your hand, you wouldn't want mitosis to go through or you could end up with a stomach sell on your hand. Meiosis reproduces the same type of cell, for example somatic cells(human cells).

Meiosis provides genetic diversity. Mitosis is used in most cell reproduction (which is fine when they do the same job). Meiosis is like sexual reproduction for cells, with the acceptation that there is only one parent cell.
