Learning Outcomes 24-1 Identify the organs of the digestive system, list their major functions, describe the histology of the digestive tract, and outline the mechanisms that regulate digestion. 24-2 Discuss the anatomy of the oral cavity, and list the functions of its major structures and regio...
Another critical part of preparation is making sure your body and mind are ready for what's to come. That means you want to be well-fueled and well-hydrated. An hour or two before your workout, have a light snack and drink some water. If you're doing morning workouts, try to get u...
At 3days post fertilization - dpf (2days post hatching - dph) larvae were reared in three 40-L tanks (30-L water volume; initial n=2700 larvae per tank; 28.3 +/- 0.4 degrees C, pH 6.9 +/- 0.2, dissolved oxygen 8.2 +/- 0.5mgL(-1), N-NO2 0.04 +/- 0.02mgL(-1), N-NH4 ...
They are differentiated by the absence of the pleopods' first pair. The three genera of the Astacidae, of the other three Northern Hemisphere families, live in western North America and western Eurasia, while the 15 genera of the family Cambaridae and the single genus of Cambaroididae, which...
In addition to their use in movement, tube feet are also used for gas exchange. Through their tube feet, sea stars can take in oxygen and release carbon dioxide. 05 of 07 Stomach Rodger Jackman/Getty Images One interesting feature of sea stars is that they can evert their stomach. This ...
After acquisition training, all the groups were subjected to the probe trial phase, during which the platform was removed from the tank to test the spatial memory of the animals. Treatment with MEPC (3, 30 or 100 mg/kg) effectively reduced the escape latency on the fourth day by ≥38 s...
Oxygen consumption increases sharply24 Frequent embryonic movement within egg 60%-75% of eggs are negatively buoyant Urea excretion rate and urea transporter gene expression reaches peak level around 36 hpf and steadily decreases thereafter42 39 ...
The cardiovascular apparatus is a transport circuit that carries blood cells, oxygen and nutrients to cells of the body’s organs, and wastes produced by working cells to their final destinations (mainly lungs, liver, and kidneys). It is involved in both mass and heat transfer. This is a pr...
RCA formation increases a plant root's capacity for water and nutrient acquisition, thereby reducing the metabolic costs of soil explora- tion and allowing it to grow larger [23, 24]. It has also been shown that RCA plays a central role in improving a plant's capacity to transport oxygen ...
