True, the vitreous humor is a clear, watery fluid that helps maintain the intraocular pressure of the eye and provides nutrients for the avascular lens and cornea.
Vitreous humor is also known as aqueous humor or vitreous liquid. The word vitreous means transparent, and humor means liquid. It is a clear jelly-like substance that fills the inside of the eyeball. As a person ages, the vitreous humor becomes more liquid. It plays an important role in providing metabolic nutrient requirements of the lens, coordinating eye growth and providing support to the retina.
The cornea helps our eyes to focus light so we can see clearly. It is the transparent and front part of the human eye that covers the iris, anterior chamber, and pupil, along with the anterior chamber and lens.

Answer:
The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells. The mechanisms involved in the cell cycle are highly conserved across eukaryotes. Organisms as diverse as protists, plants, and animals employ similar steps.
Genomic DNA
Before discussing the steps a cell undertakes to replicate, a deeper understanding of the structure and function of a cell’s genetic information is necessary. A cell’s complete complement of DNA is called its genome. In prokaryotes, the genome is composed of a single, double-stranded DNA molecule in the form of a loop or circle. The region in the cell containing this genetic material is called a nucleoid. Some prokaryotes also have smaller loops of DNA called plasmids that are not essential for normal growth.
In eukaryotes, the genome comprises several double-stranded, linear DNA molecules (Figure 6.2) bound with proteins to form complexes called chromosomes. Each species of eukaryote has a characteristic number of chromosomes in the nuclei of its cells. Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. The letter n is used to represent a single set of chromosomes; therefore a diploid organism is designated 2n. Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.
