<span>Causes Of Melanoma. Ultraviolet rays Most skin cancers are caused by too much exposure to the sun's ultraviolet (UV) rays. The two types of UV rays that cause melanoma are UV-A and UV-B rays.</span>
Answer:
Morphogenesis is the formation of the structure of an organism or part. Which involves the differentiation and growth of cells and tissues and organs during development. They are important to living organisms because that is how they are developed early on (formation of the structure of the organism, then differentiation of the growing cells and tissues during this development).
Apoptosis is programmed cell death. When a cells DNA is damaged (or it is not attached to a layer of cells) the cell self destructs. This prevents cancerous cells from growing.
Answer:
Surface tension due to cohesion
Explanation:
Water molecules are polar meaning they have dipoles. The hydrogen end is partially positive while the oxygen end is partially negative. This is because oxygen with high atomic mass attracting most of the molecule's electron cloud to its end.
Due to this phenomenon water molecules act like little magnets that attract each other. The attraction of the molecules forms hydrogen bonds with each other. This is called cohesion (attraction of similar molecules). Due to this, water is able to create a surface tension that acts like a ‘skin’ and can support some weight (including its own weight) without collapsing.
Tibialis anterior.
Explanation:
Tibialis anterior is the muscle of lower limb that originates from the upper two-third of lateral surface of tibia and attaches the heel (calcaneous ) via heel cord and plantar.
When the knee is extended, this muscle results in flexing of the foot .
This injury also functions in keeping the balance of the body when we are standing or even when we are walking.
Answer:
To calculate power we need "time"
Explanation:
In physics, power is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power. The dimension of power is energy divided by time.
