Biology

QuestionAnswer
Convergent Evolution The acquisition of the same biological trait in unrelated lineages
Divergent Evolution The vertebrate limb is one example of this type of evolution. The limb in many different species has a common origin, but has evolved in overall structure and function.
Basal Metabolic Rate minimal caloric requirement needed to sustain life in a resting individual
Heart rate (Beats/Minute) * Stroke Volume (Volume/Beat) = Volume/Minute = Delta Pressure/Resistance Cardiac Output
Septic Shock decreased tissue perfusion and oxygen delivery as a result of severe infection and sepsis
Parietal Pleura portion of the pleura external to the pulmonary pleura. lines the inner surface of the chest wall, covers the diaphragm, and is reflected over the structures occupying the middle of the thorax
Visceral (Pulmonary) Pleura attached directly to the lungs, as opposed to the parietal pleura, which is attached to the opposing thoracic cavity. The space between these two delicate membranes is known as the intrapleural space.
Mediastinum central compartment of the thoracic cavity. It contains the heart, the great vessels of the heart, esophagus, trachea, phrenic nerve, cardiac nerve, thoracic duct, thymus, and lymph nodes of the central chest.
Gama-aminobutyric acid (GABA) chief inhibitory neurotransmitter in the mammalian central nervous system. It plays a role in regulating neuronal excitability throughout the nervous system. In humans, also directly responsible for the regulation of muscle tone
Hilum part of an organ where structures such as blood vessels and nerves enter
R-selection predominates in unstable or unpredictable environments as the ability to reproduce quickly is crucial. Traits that are thought to be characteristic include: high fecundity, small body size, early maturity onset, short generation time
Fecundity Ability to reproduce
K-selection predominates in stable or predictable environments as the ability to compete successfully for limited resources is crucial and populations typically are very constant and close to the maximum that the environment can bear.
Gram Equivalent Mass Mass/# H+ = Mass/# OH- = Mass/# Equivalent
Genetic Drift change in the frequency of an allele in a population due to random sampling. The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.
Perineum Area between the scrotum and anus.
Peritoneal Cavity Abdominal Cavity
Endomitosis Endoreduplication without nuclear or cellular division, resulting in cells with many copies of the same chromosome occupying a single nucleus

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
