Answer:
Patches of fibrocartilage formed in the healing of a fracture are called <u>soft callus</u>, whereas the bony collar formed around the fracture is called <u>hard callus</u>.
Explanation:
In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
The best answer would be the butterfly. Many insects go through different physical changes during growth. These insects include the butterfly. From being an egg it turned into a larva and grown into a caterpillar which later on become a butterfly.
Answer:
Method A is conduction and Method B is radiation.
Explanation:
Driving the situation in which the heat spreads through a "conductor". That is, although it is not in direct contact with the heat source, a body can modify its thermal energy if there is heat conduction by another body, or by another part of the same body. For example, while cooking something, if we leave a spoon against the pan, which is on the fire, after a while it will heat up too.
Heat is energy in transit. This energy is transported by means of electromagnetic waves in the infrared frequency. In the transmission of heat by radiation, this fact is more evident. All bodies emit radiation, just having a temperature. The only difference between light and heat is the frequency of radiation. Thermoses are a good example of thermal radiation. The walls of the thermos are double and silver. The double walls are separated by practically a vacuum, in such a way that the heat exchanges by conduction or convection are minimized, as they need a material medium to occur. The silver walls, on the other hand, minimize heat exchanges by radiation, thus making sure that the liquid inside the bottle does not lose or receive heat.
