Examples of apex in the following topics:
-
- One of the most important environmental consequences of ecosystem dynamics is biomagnification: the increasing concentration of persistent, toxic substances in organisms at each trophic level, from the primary producers to the apex consumers.
- In some aquatic ecosystems, organisms from each trophic level consumed many organisms of the lower level, which caused DDT to increase in birds (apex consumers) that ate fish.
- The apex consumer (walleye) had more than four times the amount of PCBs compared to phytoplankton.
-
- The light at the apex of the cone is focused at the plane of the specimen; as this light moves past the specimen plane it spreads again into a hollow cone.
- When a sample is on the stage, the light at the apex of the cone strikes it.
-
- The apex of Minoan civilization occurred during the Neopalatial period, and lasted from 1700 to 1450 BCE.
-
- The apex of the patella
faces inferiorly and connects to the tibia tuberosity through the patella
ligament that attaches to the anterior surface.
-
- The Protopalatial period of Minoan civilization (1900 to 1700 BCE) and the Neopalatial Period (1700-1450 BCE) saw the establishment of administrative centers on Crete and the apex of Minoan civilization, respectively.
-
- In this case, the heart rate is determined by auscultation or audible sounds at the heart apex, not the pulse.
- The pulse deficit (difference between heartbeats and pulsations at the periphery) is determined by simultaneous palpation at the radial artery and auscultation at the heart apex.
-
- The apex (tip) of the shoot contains the apical meristem within the apical bud.
-
- In the Lake Ontario ecosystem food web, only three energy transfers occurred between the primary producer (green algae) and the tertiary, or apex, consumer (Chinook salmon) .
- Primary producers are outlined in green, primary consumers in orange, secondary consumers in blue, and tertiary (apex) consumers in purple.
-
- Higher-level consumers feed on the next lower trophic levels, and so on, up to the organisms at the top of the food chain, which are called the apex consumers.
- Primary producers are outlined in green, primary consumers in orange, secondary consumers in blue, and tertiary (apex) consumers in purple.
-
- Finally, the Purkinje fibers conduct the impulse from the apex of the heart up the ventricular myocardium, causing the ventricles to contract.
- The signal is (b) delayed at the atrioventricular node before it is passed on to the (c) heart apex.
