Intro to Biology
The basic unit of structure and function in all living organisms?
What is a Cell?
This atom in a water molecule carries a partial negative charge.
What is Oxygen?
This organelle contains the DNA in a Eukaryotic Cell.
What is a nucleus?
The name for a monomer of a carbohydrate.
What is a monosaccharide?
Fill in the blank
Domain, Supergroup, Kingdom, Phylum, Class, Order, ____, Genus, Species
What is Family?
This term describes the maintenance of relatively stable internal conditions despite changes in the environment.
What is homeostasis?
This property allows a water strider to stand on the surface of water.
What is surface tension?
This region contains the DNA of a prokaryotic cell.
What is a Nucleoid?
This biomolecule includes fats, oils, and phospholipids.
What is lipids?
This process builds larger biological molecules by removing water.
What is dehydration synthesis?
This is the level of organization made up of all the different populations living and interacting in an area.
What is community?
Water can climb up a narrow tube because of the combined effects of these two properties.
What is Cohesion and Adhesion?
This organelle is in both eukaryotic and prokaryotic cells and aids in protein synthesis.
What is ribosomes?
Explain the properties of the head and tail in a phospholipid.
What is a hydrophilic head?
What is a hydrophobic tail?
This biomolecule is made from amino acids and can function as an enzyme.
What is a protein?
This organism is referred to as an extremophile and lacks a membrane-bound nucleus. What domain does it belong to? Is it a prokaryote or eukaryote?
What is Archaea?
What is a prokaryote?
A solution changes from pH 6 to pH 4. Compared with the original solution, it now has this many times greater H⁺ concentration.
What is 100 times?
This organelle produces most of the Cell's ATP
What is a mitochondria?
A chain of amino acids folds into a specific three-dimensional shape. Why is that shape important?
Shape of a protein determines its function.
A molecule that has both polar and non-polar regions.
What is Amphipathic?
A mutation causes some bacteria to survive an antibiotic while others die. After several generations, most of the bacteria are resistant. What biological process explains this change?
What is Natural Selection
Blood needs to stay within a narrow pH range. Substances that resist large changes in pH help maintain this stability and are called this.
What is Buffers?
This organelle is involved with waste and recycling and is in animal cells but not plant cells.
What is Lysosomes?
A student has a large protein and wants to separate it into amino acids. Should the student use dehydration synthesis or hydrolysis?
What is hydrolysis?
A cell is too large to exchange nutrients and wastes efficiently. Which concept from Chapter 4 explains why?
What is Surface-Area-To-Volume Ratio?
