A SUBATOMIC PARTICLE HAS A NEGATIVE CHARGE AND IS FOUND IN A SHELL OF THE ATOM. WHAT IS THE PARTICLE? AN ELECTRON MALE PEACOCKS COMPETE WITH ONE ANOTHER TO MATE FEMALE PEACOCKS. MALES WITH MORE COLORFUL TAIL FEATHERS ATTRACT FEMALE MATES AT A HIGHER RATE THAN THOSE W/O. THEREFORE MALE PEACOCKS HAVE COLORFUL TAIL FEATHERS, WHEREAS FEMALE PEACOCKS DO NOT. WHAT IS THIS AN EXAMPLE OF? SEXUAL SELECTION A GARDENER MAINTAINS A SPECIES OF ROSE THAT PRODUCD EITHER YELLO FLOWERS ( THE DOMINANT PHENOTYPE...

Amino Acids building blocks of proteins Carbohydrates the starches and sugars present in foods Fats lipids that are solid at room temperature; composing of glycerol and saturated fatty acids Glucose a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates; primary product (output) of photosynthesis and primary reactant (input) of cellular respiration Hydrophillic attracted to water (polar); refers to molecules that are water soluble Hydr...

Abiotic Non-living Ex. A rock crystal can "grow" in a simple fashion. But rock crystals don't sense or respond to changing environments thus they aren't alive. Biotic living - Be made of materials organized in hierarchical patterns. - Use energy and raw materials to survive. - Sense and respond to changing environments also to maintain homeostasis. - Grow, develop, and reproduce. - Evolving populations Atom Basic unit of matter Molecule a chemical structure consisting of at least two atom...

Abiotic Non-living, may be within or made by a living organism. Biotic Living. Matter is considered ______ if it was ever alive at some point in time Atom Smallest level. The basic unit of matter. Consists of a dense nucleus surrounded by electrons. Molecule Second level. A chemical structure consisting of at least two atoms held together by a chemical bond. Macromolecule Third level. Biologically important molecules that are technically polymers. Example: DNA. Cell Fourth level. The fundam...

Biology the scientific study of life Characteristics of Life 1. Be made of materials organized in a hierarchical pattern. 2. Use energy and raw materials to survive 3. Sense and respond to changing environments and maintain internal stability, or homeostasis. 4. Grow, develop, and reproduce. 5. Be part of a population that evolves. The Cell the smallest unit that displays all characteristics of life Matter Any substance that has mass and takes up space. All matter can be classified as biotic ...

Features of DNA Function: Stores genetic information. Location: Remains in the nucleus. Structure: Double helix. Sugar: Deoxyribose. Pyrimidines: Cytosine, Thymine. Purines: Adenine, guanine. Features of RNA Function: Involved in protein synthesis. Location: Leaves the nucleus. Structure: Usually single-stranded. Sugar: Ribose. Pyrimidines: Cytosine, uracil. Purines: Adenine, guanine. Actin Filament in the Cytoskeleton which has a prominent role in cell movement, maintaining cell shape, and co...

The two new daughter cells will be haploid, but the DNA they contain is still replicated. The homologous chromosomes have separated and are ready to start the second division, but they have not yet begun the second round of division. Which stage of the cell cycle is this cell in? Telophase I Homologous pairs of chromosomes have separated into two cells. Sister chromatids in each cell have not yet lined up in the middle of the cell. Which stage of the cell cycle is this? Prophase II Which typ...

Coevolution Event The process by which two or more species evolve in tandem by exerting selection pressures on each other Speciation Event A lineage-splitting event that produces two or more separate species. Phylogenetic Event The evolutionary development and history of a species or higher taxonomic grouping of organisms. Also called phylogenesis. The evolutionary development of an organ or other part of an organism Homology Event Shared trait among species Mutation A Mutation occurs when a...

Which item would be classified as biotic? -light -wind -temperature -fungus fungus Which item is an atom? -carbon dioxide -nitrogen -sucrose -methane nitrogen Largemouth bass have recently been introduced into ponds that previously did not contain any large, predatory fish. Which adaptation would help the existing population of small, prey species of fish avoid predation from the largemouth bass? -fins with smaller surface areas -faster average swim speed -more noticeable body coloration -...
