Resident microflora:
CaHeK987 [17]

Answer:

Resident microflora b. may be responsible for opportunistic infections in immunocompromised

Explanation:

It is almost impossible to found these microorganisms in the stomach because of the acidic conditions, most of them are not adapted to this type of environment. Resident microflora is not transient, is actually permanent. However, resident microflora may be responsible for ooportunistic infections in immunocompromised and they can also increase the intensity of the disease produced by that pathogen.

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1116.2 cm cubed and a standard deviation of 127.7 cm cubed. Use the g
Shkiper50 [21]

Answer:

Yes

Explanation:

Range rule of thumb predicts the Range to be  a multiple of 4 of the standard deviation or to be four times  the standard deviation. Making the usual values equal to 2 standard deviations distanct of the mean of the data distribution.

In a given distribution with mean and standard deviation that is obtained, the usual values in mean (as seen in the attached image).

2*standard deviation and mean + 2*standard deviation.

If the data point is not up to the mean

- 2* standard deviation is taken to be significantly low.

If the data point is more than the mean

+ 2*standard deviation is taken to be significantly high.

Let's take the xbar to be the mean and s as standard deviaiton

Given,

mean, xbar = 1116.2

standard deviation, s =127.7

The range rule of thumb shows that the usual values are within 2 standard deviations from the mean

Lower boundary

      = xbar - 2s

       = 1116.2 - 2(127.7)

       = 860.8

Upper boundary

      = xbar + 2s

       = 1116.2 + 2(127.7)

       = 1371.6

We should note that 1411.6 is not between 860.8 and 1371.6, which connotes that 1411.6cm^3 is unusually high.

Choose the accurate statements about how communication by the nervous and endocrine systems differs. Check all that apply. Check
andreev551 [17]

Answer:

The nervous system releases neurotransmitters at synapses at specific target cells & The endocrine system reacts more slowly to stimuli, often taking seconds to days.

Explanation:

The nervous system is very specific with where the neurotransmitters go so they will affect target cells. The endocrine system is slower than the nervous system because the hormones travel through the blood so it takes much longer to reach the designated area.
