The endotherms have higher metabolic rates per gram as compared to the ectotherms. This causes change in physiology such that they have higher breathing and heart rates. Also, they have higher mitochondria numbers per gram of tissue.
Endotherms are the organisms that can maintain a constant body temperature inside, unaffected by the temperature outside. They are also called warm-blooded animals. The examples include: mammals and birds. The opposite of endotherms are the ectotherms who cannot maintain a constant body temperature.

Fluid is filtered from blood as it enters a capillary due to the hydrostatic pressure from the heart, but fluid is reabsorbed as the blood exits a capillary due to the osmotic pressure from proteins in the plasma
The appearance of edema is significantly influenced by plasma colloid osmotic pressure (COP). A greater understanding of the importance of COP determinations in clinical practice has resulted from the development of a straightforward method for COP measurement that is based on an electronic pressure transducer and a semipermeable membrane system.
The measured COP replicates the calculated value based on serum proteins in a steady state. A derived value is unreliable in pathologic sera. Average human plasma COP is 25.4 mm Hg. This value tends to drop with advancing years, is lower in females, and also drops in subjects confined to bed rest.

Common feature of f-actin, microtubule, and intermediate filament they all provide tracks for molecular motors.
F-actin, microtubules, and intermediate filaments are all cytoskeletal elements found in eukaryotic cells. They play a crucial role in maintaining cell shape and facilitating cell movement, among other functions. One common feature of these three structures is that they all serve as tracks for molecular motors, which are protein complexes that move along the cytoskeleton and transport various cellular cargo. The molecular motors move along the filaments and use the energy from ATP hydrolysis to power their movement. This movement is essential for various cellular processes such as cell division, intracellular transport, and maintenance of cell shape.

What is the primary benefit of perennial plants?
A) Increased crop yields
B) Decreased pesticide use
C) Increased nitrogen fixing
D) Easy integration of crop rotation
E) Decreased erosion
The primary benefit of perennial plants is decreased erosion.
Perennial plants are those that live for more than two years and typically grow back each year from their roots. This persistent growth provides a permanent cover on the soil, which helps to reduce erosion. Unlike annual crops, which are grown from seed each year and are left bare over the winter, perennials offer continuous protection to the soil, reducing the impact of wind and water and helping to keep the soil in place. This can lead to improved soil health and fertility, as well as decreased runoff, which can have a positive impact on water quality.

The synaptic cleft is the space between the motor end plate of the muscle fiber and the neuron's terminal button. This statement is true.
The neuron releases the neurotransmitter acetylcholine (ACH), which acts as a chemical messenger. ACH travels across the synaptic cleft to bind to receptors on the muscle fiber, much like a key fits into a specific lock.
The end result of the binding of ACH is muscle contraction. The binding of acetylcholine (ACH) to its receptors on the muscle fiber triggers a series of events that leads to a muscle contraction.
