DNA - deoxyribonucleic acid.The main constituent of chromosomes. It is the carrier of genetic information
<span>Genes - A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring </span>
Chromosomes - A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes... Keep this in mind: Inside every cell in your body are little "blueprints" that make you what you are! Those "blueprints," called DNA, contain everything necessary to sustain human life as well as physical traits that make you unique. The color of your hair, skin, and eyes; how tall or short you are; whether you're a man or a woman; the dimple in your chin; the bushy eyebrows-all these traits are passed on to you from your parents.
Inside the spiral-shaped DNA molecule are 26 pair of x-shaped chromosomes comprised of genes (little complex, protein packages that determine heredity). As a cell divides, the DNA molecule splits into equal halves and each half becomes part of a new cell. In human reproduction, a female egg (13 pair of chromosomes) joins up with a male sperm cell (13 pair of chromosomes), bringing the total number back up to 26 pair again.

Explanation:
Answer:
Seafloor spreading helps explain continental drift in the theory of plate tectonics. ... Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ridge push. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
