Blood is made up of plasma, and the formed elements red blood cells, white blood cells, and platelets. a blood sample is collected and is determined to be 56% plasma and 1% white blood cells and platelets. what is the hematocrit of this blood sample?

43%

Explanation:

When you collect blood in a tube and centrifuge it, the elements that compose it separate in three distinct layers:

If 56% of the blood sample is plasma and 1% is white blood cells and platelets, then the hematocrit is 100% - 56% - 1% = 43%.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
