Damm [24]

Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.  

To find: P(100 < 152)

Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.

Solution:

Mean u = 152, std s = 18

Z score = \frac{X-u}{s} = \frac{100-152}{18} = -2.89

The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.

P(Z=-2.89) = 0.0019

The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.

Thus the probability of 100 mm Hg blood pressure is 0.0019.

Why might knowledge of the gene and protein sequences of a species be useful in classifying that species? (4 points)
lara [203]

It would make it possible to compare that species to other species at a level deeper than outward appearance

Explanation:

The proteins like hemoglobin and enzymes can be studied to see whether organism which are similar in form can also be related to each other. Its differences found in these proteins' amino acid sequences will present how closely or distantly related an organism is to another.

Sponges have no "true tissues." what does this mean
artcher [175]
<span>Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells. This is the simplest kind of cellular organization found among parazoans.
