For example:
Sickle cell anemia is caused by an abnormal hemoglobin in red blood cells. hemoglobin is the red pigment found in red blood cells for carrying oxygen.The abnormality arises from a genetic mutation in the DNA gene that codes for the beta chain of the protein called globin of which hemoglobin is made of.In the beta chain, the sixth amino acid called glutamine is replaced by another one called valine.This one change in the amino acids cause the hemoglobin protein to behave abnormally, causing red blood cells to lose their normal spherical shape and become bent like a sickle, hence the name "sickle cell" anemia
Answer:
B. There is a moderate variation in birth weight.
Explanation:
The graph shows the "Number of Babies" on its<em> y-axis</em> and the "Weight in Pounds" on its x-axis. The line graph shows that the re is a moderate variation in birth weight and that occurs when the line of the graph starts to go up after 2.5 pounds and starts going down after 6.5 pounds. Then, the number of babies becomes constant again upon reaching 10.5 pounds.
Letter A <em>(There is no variation in birth weight) </em>is false. The weight in pounds on the y-axis shows a variation from 1 pound to 13 pounds and it also shows that many babies have a 6.5-weight in pounds. So, there is clearly variation here.
Letter C <em>(Variation changes over time)</em> is false. There is no indicator of time in the graph. It only shows two variables.
So, this explains the answer.
<span>Decrease. Net filtration is the equilibrium force that can be measured in the capsular space of the renal corpuscle. This determines how much water and small dissolved solutes leave the blood in the glomerulus. The equation for net filtration is: (IFOP); NFP = GBHP - (CHP + BCOP). The Net Filtration is generally around 10 mm Hg.</span>
Answer:
P - grandparent, F1 - Mom and F2 - you
Explanation:
According to Gregor Mendel the P generation is the starting generation and in this case it the the Mom's grandparent, F1 filial generation is the offspring of the the grandparent which the Mom and the he or she is the F2 generation or second generation from the grandparent.
