A zygote is a cell formed by sperm and an egg
An embryo is a developed zygote with some organs
A fetus is a developing individual
How are DNA, genes, and chromosomes related?
Chromosomes contain all basic heredity information that genes and DNA use. Chromosomes are composed of sequences of DNA
Relfexes
Unlearned, involuntary responses that occur automatically in the presence of certain stimuli
Habituation
The decrease in the response to a stimulus that occurs after repeated presentations of the same stimulus
