what is sexual reproduction
the production of an offspring from the joining of a sperm and an egg

a type of reproduction in which the genetic materials from two different cells combined, producing an offspring is what

what describes how a trait appears
phenotype does
homologous structures are
body parts of organisms that are similar in structure and position but different in function
plants respond to what
what is a protein used for
to build and repair muscles and bones
what are daughter cells
the cell cycle that results in two genetically identical cells
the study of how traits are passed from parents to offspring is called
heredity
comparative anatomy is
the study of similarities and differences among structures of living species
long day and short day plants are examples of plants that respond to
photoperiodism
what are substances formed by joining smaller molecules together
nucleic acids
cell division in prokaryotes is called what
what is the code for a protein called
gene
why do scientists think the fossil record is incomplete
fossils decompose over time
what happens in photosynthesis
plants convert light energy, water, and carbon dioxide into the food- energy molecule glucose through a series of chemicals, this gives off oxygen
