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 =
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.
Answer:a
Explanation:the rough endoplasmic reticulum is a cell organelle that has ribobomes attached to it.the ribobomes attached gives it a coarse appearance. Rough endoplasmic reticulum is involved in the production of protein to be transported out of the cell.
The ribosomes pack amino acid into the proteins and then passes it to the rough endoplasmic reticulum.from there it is pass to the cis end of the Golgi apparatus.in the Golgi apparatus,further modifications takes place and the proteins is transported out of the cell.
Free ribobomes synthesize proteins meant for the cytosol.
The smooth endoplasmic reticulum synthesis non-protein molecules such as steroids and lipids.
Fire naturally occurs in a grassland ecosystem and it helps the environment stay healthy and strong. I promotes richer soil as well as gets rid of excess leaves scattered around. After a fire, grassland ecosystems can grow again and be better than they were before.
