The FedEx of the cell are the vesicles.
Vesicles are the structures in which many cell materials are packed and transported. Vesicles are cellular organelles that are composed of a lipid bilayer and they function as cellular envelopes to transport cell materials from one place to another inside the cell.
An example of one material is protein. After a particular protein has been synthesized in the ribosomes of the cell, it is packaged in a vesicle called a transport vesicle. The vesicle carries this package to the Golgi apparatus for final tweaking after which it is again repacked in a new vesicle which transports it to its required destination in the cell.
Answer:
The correct answer is - autonomic (visceral) reflexes.
Explanation:
Autonomic or visceral reflexes is somewhat similar somatic reflexes but visceral reflex takes place in various soft tissues and muscles present in soft organs such as digestive, cardiac muscles, reproductive muscles, and others.
Visceral or autonomic reflexes include activation of smooth muscles, glands, and dilation of pupils, vomiting, defecating, sweating, blood pressure and many more body function regulating.
Thus, the correct answer is - autonomic (visceral) reflexes.
Answer:
The phenomenon in which osteoclast results in the degradation of the old bones and encourages the generation of novel bones by the assistance of osteoblasts is termed as bone remodeling. The remodeling of bones takes place throughout life, that is, whenever it is required. Some of the elements that monitor the process of bone remodeling are the concentration of serum vitamin D, serum level of calcium, and the level of calcitonin and growth hormone in the blood.
Thus, whenever the bone gets degrade or becomes useless it gets replaced by the process of bone remodeling. Hence, the hypothesis of 'use it' here signifies the usage of bones or else they will get useless or get degrade.
In the process of bone remodeling formation of more dense bones takes place due to the renewal of the destructed bones. This results in the presence of both the damaged bones and the newly formed bones at the same time, hence, it can be concluded that more bones are present at the time of bone remodeling.
Answer:
There are two phases of the cardiac cycle: The diastole phase and the systole phase. In the diastole phase, heart ventricles relax and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart to arteries.
