releasing hormone – A kind of hormone released from the hypothalamus that makes the anterior pituitary secrete hormones.
electron – A negatively charged particle; located outside the atomic nucleus.
Evolution – The process by which the range of organisms on Earth change. Takes place by means of natural selection.
Müllerian mimicry – Two or more unpalatable species resemble each other.
long term energy 9.2 – after 15-20 minutes, fat is broken down
homeostasis – Process by which organisms maintain a relatively stable internal environment. **think of it as a thermostat inside the organism/body. ie. get too hot, body has you sweat to release some excess heat
Atom – Building block of matter; contains subatomic particles: neutrons, protons, and electrons.
are openings on the bottom surfurce of leaves where wter an doxygen exit and carbon dioxide enters – stomata
Active Transport – – breaks concentration gradient but needs to use ATP (energy for cell) – are very specific -pumps act as enzymes with active sites so they often pump only one substrate
What are the three distinct types of muscles in mammals? – Skeletal, Cardiac, and smooth
Tumor of the liver
Receptors – Special sructures that allow living organisms to sense the conditions of their internal or external environment.
Lipids – A group of organic compounds composed mostly of carbon and hydrogen including a proportionately smaller amount of oxygen; are insoluble in water, serve as a source of stored energy, and are a component of cell membranes.
klinokinesis – a change in the rate of turning
Vegetative Organs – The parts of a plant (such as stems, roots, and leaves) that are not involved in reproduction
exergonic reaction – reaction which results in a net release of free energy
pith ray – Undifferentiated cells between vascular bundles, extending from the central pith core.
Tumоr оf the liver
Nuclear Envelope – what surrounds the nucleus by a double membrane
