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.
To solve this, you would need to identify the number of amino acids (20) you are dealing with and the number of positions (8) that are available in your polypeptide. so that would come out to 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 = 20^8
In the movement of sperm tail plays an important role due to which sperm is able to move.
Sperm move to the uterine tube through uterine contractions and the energy of their own flagella.
Motility of sperm is also depend upon various metabolic pathways and the mechanism of regulation.
<h3>What is causes sperm to move?</h3>
The structure of sperm contains tail which have large numbers of protons channels which are known as Hv1 channels that respond to changes in pH and concentration of zinc outside the cell.

I think the answer is c, because in a city, there is very little natural shade like trees. also, asphalt creates more heat when the sun is directly on it.
Answer:
d. a bacterium with human gene for producing insulin
Explanation:
Transgenic organisms are the organisms in which the foreign DNA is introduced by using the molecular techniques for obtaining a particular result. This foreign DNA can be introduced using a vector called plasmid vector.
One of the examples of transgenic organisms is E.coli with the human gene for producing insulin. So for producing artificial insulin, the gene which produces insulin peptide is ligated in a plasmid vector and then this plasmid is introduced in the bacterium where this plasmid replicates and produces insulin. So the correct answer is d.
