Explanation:

just did it

The job of researchers in the Astronaut Microbiome Project is to keep the astronauts healthy in space. The correct option is B.

The microbiome is defined as the collective genomes of microbes that live inside and on the human body (including bacteria, bacteriophage, fungi, protozoa, and viruses).

We know that the microbiome is essential for human health, and that when things go wrong, it can contribute to disease.

To understand how microbes influence human disease, we must first understand the microbial composition of a healthy person.

Weight gain, high blood sugar, high cholesterol, and other disorders may be exacerbated by an imbalance of unhealthy and healthy microbes in the intestines.

Their objective is to figure out how the composition of the human microbiome changes during long-term space exploration and to assess the potential impact on the health of astronauts.

Thus, the correct option is B.

answer is

10P3 = 10 x 9 x 8 = 720.

Answer:

2.01 ; 1.918

Explanation:

Given the data:

X : ____ 0 __ 1 ___ 2 ___ 3 ____ 4 ____ 5

P(x) : 0.09 _ 0.32 _0.27_0.17___0.11 __ 0.04

The mean, E(x) :

Σ(X * p(x))

= (0*0.09)+(1*0.32)+(2*0.27)+(3*0.17)+(4*0.11)+(5*0.04) = 2.01

Standard deviation = sqrt(variance)

Variance = Var(x)

Var(X) = Σx²*p(x) - E(x)

Σ[(0^2 * 0.09) + (1^2 * 0.32) + (2^2 * 0.27) + (3^2 * 0.17) + (4^2 * 0.11) + (5^2 * 0.04)] - 2.01

= 5.69 - 2.01

= 3.68

SD(x) =sqrt(3.68)

SD(x) = 1.918
