Intro to zoology Flashcards
Zoology
is the study of animals. It is one of the broadest fields in all of science because of the immense variety of animals and the complexity of the processes occurring within animals. A branch of biology that specifically deals with the study of animals-their anatomy, physiology, evolution, reproduction, interactions, including embryology and heredity, among others.
Anatomy
study of the structure of entire
organisms and their parts
Cytology
study of the structure and function of
cells.
Comparative genomics and bioinfomatics
study of the structure, function, and evolution of
the genetic composition of groups of animals
using computer-based computational method
Ecology
study of the interaction of organisms
with their environment
Embryology
study of the development of an
animal from the fertilized egg to birth or hatching.
Genetics
study of the mechanisms of
transmission of traits from parents to offspring
Histology
study of tissues
Molecular Biology
study of subcellular details of
structure and function
Parasitology
study of animals that live in or on other organisms at the expense of the host
Physiology
study of the function of organisms
and their parts
Systematics
study of the classification of, and
the evolutionary interrelationships among, animal groups.
Social science
It is the study of people,
culture and society
Natural science
The study that seeks to
understand the natural
world.
Physical science
Deals with matter and
energy.
Biological science
Deals with living
organisms
Aristotle
Ancient Greek philosopher in the 4th century BC who provided some of the first broad classification of living things.
He divided all living things into plants and animals.
Albertus magnus
He emphasized the notion that
information about nature could and should be collected by observing its various aspects.
Plant physiologist
studies the biological, physical, and chemical functions of a plant
Vertebrate paleontologist
The study of vertebrate fossils from primitive fishes to mammals
Analogy
similarity of functions and superficial similar structures that come from different origins
Homology
similarity of structures, some physical attributes is inherited from ancestors
Adaptive radiation
rapid diversification from ancestors to a multitude of different forms
Oncogenes
genes that have the potential to cause cancer
Islet cells
produces hormones
Unicellular organism
Organism with only a single cell
X-ray diffracitonary
a nondestructive technique that provides details about the crystallographic structure and physical properties of materials
Genotype
genetic material passed down generations
Phenotype
observable traits
Reflex action
sudden & involuntary response to stimuli
Lymphatic system
immune system, fluids in body kept in balance, protects from infections
Binomial system
used to give the specific scientific name of a species
Paleontology
study of geologic past, fossils
Ovum
single cell released by the female reproductive system
Brownian movement
random movement of microscopic particles in liquids/gases due to fluctuation
Biogenetic law
each embryo results in an adult form for an evolutionary ancestor
Line of faunal delimitation
divide of Asian and Australian species
Gastrea hypothesis of metazoan ancestry
monophyletic sponges, sponges have a difference in ancestry
homologous pairing
set of chromosomes come from father and mother, 2 sets form 1 set for zygote
Parallelism of Mendelian Segregation and chromosome behavior
genes/chromosomes are passed down from generation to generation in an altered form.
Drosophilia
genus of flies
Citric acid cycle
Krebs cycle part of cellular respiration
Mobile genetic components
transposable elements, moving genetic material, moves around within a genome or across to different genomes
Sliding filament theory
thick slides past thin during contraction, while some remain in relative length
Prions
proteins that trigger normal proteins in the brain to fold abnormally
