Answer: The osmolarity of the filtrate would be about 300 mOsm because both solutes and water are reabsorbed in the proximal tubule. As particles are reabsorbed, water follows osmotically.
Explanation:
Answer:
Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and straited and smooth muscle is involuntary and non-striated.
Skeletal muscles are found attached to bones
Cardiac muscle cells are located in the walls of the heart
Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines)
Explanation:
Answer:
Sarcoplasmic reticulum.`
Explanation:
Muscle fibers are formed by the process of myogenesis in humans. These fibers help in the contraction of the muscle and also helps in the body movement.
Sarcoplasmic reticulum is a cell organelle present in the muscle fibers that corresponds to the structure of endoplamsic reticulum. Sarcoplasmic reticulum stores the calcium ions in the muscle fibers.
Thus, the answer is sarcoplasmic reticulum.
Answer:
Option a. effector
Explanation:
Effectors acts in response to the commands of the control center in negative feedback.
Negative feedback is when the system responds to the stimulus in such that it reverses the direction in which change occurs thus maintaining homeostatis (stability).
An example of negative feedback is thermoregulation in which body temperature is regulated with skin acting as receptor to communicate information to control center (brain); sweat glands and blood vessels acting as effector which results in regulation of body temperature.
The Effectors either supports or opposes the stimulus.
Answer:
B. Adrenergic
Explanation:
The sympathetic nervous system uses noradrenaline as the main neurotransmitter. Noradrenaline acts in alfa and beta adrenergic receptors and has effects over smooth muscle, cardiac tissue, and secretory glands.
