What adaptations have plants and animals developed that allow them to survive the extreme climate of the tundra? a) thick fur b) dense hair c) retention of dead leaves d) feathered feet e) all of the above

E) All Of The Above. Because all of them give the plant/or animal a little extra protection, and protects them from the cold.

All the above(Option E)

Explanation:

The adaption that is required by the plants and animals of the tundra region must include the features that allows them to survive in extreme cold conditions.

The plants in the tundra region does allows the falling of dead leaves, they retain the dead leaves in the plant only for surviving in such conditions.

The animals their have thick fur and dense hair so that it can act as insulator to keep their body warm. They have fur in their feet to walk in such cold conditions.

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.

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.
