Aminotes exam Flashcards

Organisms that maintain a constant body temperature through internal metabolic processes.

Monotremes, marsupials, and placental mammals.

The outermost membrane surrounding an embryo in an amniotic egg.

It is a fluid-filled cavity that encases and protects the embryo.

A group of amniotes that includes mammals, characterized by certain skull features.

They have a placenta that facilitates nutrient exchange between the mother and developing fetus.

A protein found in the scales of reptiles, as well as in human hair and nails.

It provides food for the embryo and is connected to the gut by blood vessels.

Egg-laying mammals, such as the platypus and echidna.

They birth underdeveloped offspring that continue to develop in a pouch.

The protein-rich solution in an egg, commonly known as egg whites.

It acts as a waste storage area for the embryo.

A part of the brain in mammals that allows for improved cognition.

Hair, mammary glands, and three middle ear bones.

A group of amniotes that includes reptiles and birds.

Feathers are a key adaptation for flight and insulation.

An organ that connects the developing fetus to the uterus wall for nutrient exchange.

They are the earliest living relatives of amniotes and have adaptations for life on land.

Glands in mammals that produce milk to feed offspring.

They maintain a constant body temperature and have features like feathers or hair.

A group of tetrapods that includes reptiles, birds, and mammals, characterized by having an amniotic egg.

It provides a protective outer layer for the embryo.

Organisms that rely on external sources of heat to regulate their body temperature.

Water, fat, and sugar.

A characteristic of birds that aids in flight.

Birds are classified as modern dinosaurs within the monophyletic group of reptiles.

A reproductive process where fertilization occurs inside the body, common in reptiles.

It allows for improved cognition and complex behaviors.

Mammals that birth underdeveloped offspring which continue to develop in a pouch.

They are used to convey sound and are a defining feature of mammals.
