3. the nucleus is a membrane-bound organelle found in eukaryotic cells.
5. one that will be expressed (shown) in an individual even if only one copy of the allele is present
7. a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
10. the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
12. a ribosome is a complex structure found within cells that plays a crucial role in protein synthesi
14. the total mass of living organisms in a specific area or ecosystem.
15. any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
16. the observable characteristics of an organism, including its physical traits, behavior, and biochemical properties.
19. osmosis is the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration.
20. is an organism with a genetic condition characterized by the absence or reduced presence of melanin, a pigment that gives color to skin, hair, and eyes.

1. a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
2. a is a change in the DNA sequence of an organism.
4. the total mass of living organisms in a specific area or ecosystem.
6. the fundamental unit of heredity, a segment of DNA that provides the instructions for making a specific protein or functional RNA molecule.
8. the semipermeable membrane surrounding the cytoplasm of a cell
9. a genetic trait that is only expressed when an organism has two copies of the recessive allele for that trait.
11. Proteins are complex molecules and do most of the work in cells. They are important to the structure, function, and regulation of the body.
13. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins.
17. the process of creating a genetically identical copy of a biological entity, such as a DNA sequence, cell, or organism.
18. the biochemical processes through which organisms obtain energy by converting food molecules (like glucose) into usable energy (ATP)
