|
Define Embryology
|
The branch of biology that deals with the formation, early growth, and development of living organisms
|
|
|
What is zygote?
|
This is considered the first stage of embyonic development and results from the union of male and female gametes. The fertalized egg that results is reffered to as the zygote.
|
|
|
Do Lamphreys lack Jaws?
|
Lampreys don't have jaws.
|
|
|
What is a marsupial?
|
any mammal of the order Marsupialia, in which the young are born in an immature state and continue development in the marsupium. The order occurs mainly in Australia and South and Central America and includes the opossums, bandicoots, koala, wombats, and kangaroos
|
|
|
Which mammal lays eggs?
|
Platipus
|
|
|
What are the five characteristics of Chordata?
|
-Notochord present at some developmental stage
-dorsal hollow nerve chord - Pharynx with slits(sometimes called "gill slits") -pharynx with endostyle or it's derivative the thyroid gland -short postanal tail |
|
|
Flexion
|
Bending movement that decreases the angle between two parts. Bending the elbow, or clenching a hand into a fist, are examples of flexion. When sitting down, the knees are flexed. Flexion of the hip or shoulder moves the limb forward (towards the anterior side of the body)
|
|
|
Ectotherm
|
refers to organisms that control body temperature through external means. As a result, organisms are dependent on environmental heat sources[1] and have relatively low metabolic rates
|
|
|
Abduction
|
A motion that pulls a structure or part away from the midline of the body (or, in the case of fingers and toes, spreading the digits apart, away from the centerline of the hand or foot). Abduction of the wrist is called radial deviation. Raising the arms laterally, to the sides, is an example of abduction.
|
|
|
extension
|
The opposite of flexion; a straightening movement that increases the angle between body parts. In a conventional handshake, the fingers are fully extended. When standing up, the knees are extended. Extension of the hip or shoulder moves the limb backward (towards the posterior side of the body).
|
|
|
adduction
|
A motion that pulls a structure or part towards the midline of the body, or towards the midline of a limb. Dropping the arms to the sides, or bringing the knees together, are examples of adduction. In the case of the fingers or toes, adduction is closing the digits together. Adduction of the wrist is called ulnar deviation
|
|
|
endotherm
|
"within-heating" describes a process or reaction that absorbs energy in the form of heat.
|
|
|
What can amphibians breathe through?
|
Gils, skin and lungs.
|
|
|
What animal is capable of true flight?
|
bat
|
|
|
Which class of vertebrates have fur or hair?
|
birds and mammals
|
|
|
What is tissue?
|
Tissue is a cellular organizational level intermediate between cells and a complete organism. Hence, a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function
|
|
|
What are homologous appendages?
|
"appendage" is a general term that covers any of the homologous body parts that may extend from a body segment. These include antennae, mouthparts (including mandibles, maxillae and maxillipeds), wings, elytra, gills, walking legs (pereiopods), swimming legs (pleopods), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages
|
|
|
Define viviparous
|
bringing forth living young rather than eggs, as most mammals and some reptiles and fishes.
|
|
|
What is a monotreme?
|
Mammals that lay eggs instead of giving birth to live young.
|
|
|
What is an example of a monotreme?
|
Platypus
|
