Describe the origin of each strand of the new double helices created after dna replication.

Each new strand which is also called the daughter strand is created by replicating a parent strand which is called the template strand.

Explanation:

DNA is the genetic material in most of the life forms. The DNA is replicated in a semiconservative way which means one strand in DNA is an old parent strand and another is a new strand.

Each strand in the DNA acts as the template strand during replication and DNA polymerase makes a new strand that is complementary to the parent strand. Therefore in a DNA double helix, one strand comes from parent DNA and another is newly made which is complementary to the parent strand.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

i would say it is
