Answer:
Uses each strand of a DNA molecule as a template for the creation of a new strand. (Option A)
Explanation:
DNA replication: It is defined as the uses of each strand of a DNA double helix act as a template for the creation of a new complementary strand. During the process of DNA replication, one leading strand (new strand) is made as a continuous piece and another lagging strand is made in small pieces.
DNA replication process, in addition to DNA polymerase, requires other enzymes such as DNA ligase, DNA helicase, DNA primase, and topoisomerase. DNA polymerase is the key molecule in the DNA replication, it is responsible for the synthesizing DNA. They help to add one by one nucleotide to the growing DNA chain and incorporating only those which are act as complementary to the template.
The two DNA strands unwind from one another during semi-conservative replication, and each serves as a template for the synthesis of a new, complementary strand. Two DNA molecules are produced as a result, each with one original and one new strand.
The act of duplication is referred to as replication. DNA replication is the first step in inheritance in molecular biology. The central dogma explains how the DNA replicates itself, codes for the RNA during transcription, and then codes for the proteins during translation.
On several sources of replication along the DNA template strand, DNA replication takes place (antinsense strand). One original strand and one freshly synthesized strand are included in every copy. Although it should be guaranteed that both copies are identical, Each strand of the double helix would act as a template for the manufacture of a new strand, according to the structure of DNA (which was discovered by James D. Watson and Francis Crick in 1953). The process by which freshly created strands united with template strands to create two double helix DNA molecules was unknown.

Sorry for the handwriting
Answer;
The human eye contains more rods than cones photoreceptors.
Explanation;
-The retina of the human eye is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones.
-The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are more numerous than cones in the periphery of the retina. The cones are not as sensitive to light as the rods. However, cones are most sensitive to one of three different colors (green, red or blue).
