First you need to determine how much standard deviation the range is.
120+12*x= 96
x= 96-120/ 12= -2
120+12*y=144
y= 144-120/12= +2
Systolic blood pressure between 96 mmHg and 144 mmHg means that the blood pressure is at -2SD to +2SD. The Z-score for -2SD is 0.0228 and +2SD is 0.9772
So the percentage would be: 0.9772- 0.0228 * 100%= 95.44%
Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
Answer:
A. A diet with many saturated triglycerides and animal-derived foods.
Explanation:
<em>According to the American Heart Association, a diet in a low-saturated fat, high-fiber, high plant food diet can substantially reduce the risk of developing heart disease. In Mr.Jolly's case more salads less fat would help immensely. </em>
I wanna say photovoltaic panels. Not sure if I'm correct.
Answer:
break them down to monosaccharides
Explanation:
The covalent bonds between Carbon and Hydrogen atoms in polysaccharides and their monomers contain high energy that is tapped by cells to make ATPs (the energy currency of cell) in cellular respiration. Carbohydrates, such as amylose, glycogen, and starch, therefore, need to be broken down to smaller units like glucose that can be utilized by cells metabolic pathways. Carbohydrates are easily hydrolysed to provide energy when the body requires it.
