As organs and organ systems continue to develop in this embryo, the eyes will contain clear, transparent lenses. how does a single group of cells differentiate to produce both the transparent lens cells as well as all the other specialized cells in the completed organism? a) each cell selectively uses certain genes to make specific proteins not found in any other cell types. b) a cell selectively deletes certain copies of genes and the remaining genes produce proteins for a specific purpose. c) each cell has the same genetic composition so specific hormones are activated to produce cell types with specific structures and functions. d) specific genes for specific proteins migrate to cells; those migrated genes are activated to produce the proteins that determine the cell's structure and function.

A) each cell selectively uses certain genes to make specific proteins not found in any other cell types

Explanation:

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
