Lamarck's idea of "acquired traits" proposed that a. acquired traits are passed down from parent to offspring. b. in animals, traits that are used often will grow and change shape. c. acquired traits are not passed down from parent to offspring. d. in animals, traits that are not used often will shrink and change shape.

The correct answer is-  A. acquired traits are passed down from parent to offspring.

Lamarck proposed a theory of inheritance in 1801, which is called Inheritance of acquired traits/characteristics.

According to this theory, during a life span, a individual brings certain changes in his characteristics in order to adapt to the changing environmental conditions. These changes are called acquired traits and can be passed from one generation to the next generation (that is from parents to their offspring).

Thus, option A) is the right answer.

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.
