Answer:
a. the DNA helix breaks or unzip down the middle between the base pairs.
b. the enzyme DNA polymerase moves along the exposed strand and add complementary nucleotide to each nucleotide in each existing strand.
c. a complementary strand is created for each of the two strands of the original double helix
d. two new identical DNA molecules have been produced.
Explanation:
The process of replication ensures the doubling of genetic material before cell division occurs in a cell. the process of repliction involves the above named four steps and is mediated by different enzymes performing different functions on this genetic material within the same close range (the replisome machinery). this enzymes include the helicases, the single strand binding proteins, the topoisomerases, DNA polymerases etc. the end product of replication is that two new identical DNA molecules will be produced from one.
With the help of xylem which is present in plants
Answer:it described how carbon is recycled between earth's biosphere, hydrosphere, geosphere and atmosphere. Carbon is an essential element for all life forms so understanding how it is recycled will help us to understand factors and all the biological processes that influence them.

Answer:
What are the main working modes of AFM?
AFM operation is usually described as one of three modes, according to the nature of the tip motion: contact mode, also called static mode (as opposed to the other two modes, which are called dynamic modes); tapping mode, also called intermittent contact, AC mode, or vibrating mode, or, after the detection mechanism, amplitude modulation AFM; non-contact mode, or, again after the detection mechanism, frequency modulation AFM.
Despite the nomenclature, repulsive contact can occur or be avoided both in amplitude modulation AFM and frequency modulation AFM, depending on the settings

Homo.
The genus and species for humans is Homo sapiens, "Homo" being the genus, and "sapiens" being the species
