<span> A supercell is a type of thunderstorm. Supercell thunderstorms have an intense rotating updraft. This rotating updraft is known as a mesocyclone. Supercell thunderstorms often produce large hail and tornadoes. Large hail is created by the very strong updraft of a supercell. The updraft is strong enough to keep water suspended aloft in the storm. This causes the water to freeze. As it starts to drop, it is caught in the updraft and sent back up into the storm. This repeats several times until the hail stone is too large for the updraft to keep aloft.
It takes a thunderstorm to produce a tornado. Thunderstorms are created when cold dry air from the north interacts with warm moist air from the Gulf of Mexico. Warm moist air rises as the cold dry air sinks. This can help create atmospheric instability.
Some tornadoes are formed from supercell thunderstorms. It is known that there is air underneath the storm that is rotating horizontally. When the updraft of the storm strengthens, with the help of inflow winds, the horizontal rotating air can be tilted into the vertical. If the rotation is strong enough, a lowering from the base of the storm cloud can form and make a wall cloud. Sometimes, the wall cloud can be rotating as well.If the updraft, downdraft, and rear flank downdraft are present, this can strengthen the rotation and can create a funnel cloud. If the rotation remains strong and eventually reaches the ground, then a tornado has formed. </span>
Answer:
There are 4 types of chromosome
1.Metacentric
2. Submetacentric
3.Acrocentric
4.Telocentric
Explanation:
Chromosome are found with in the nucleus of most living cells and consist of DNA that is tightly wound into threads like structure.
Chromosome can also be classified depending on their length, number,and arm size.
Answer:
A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.
Explanation:
- A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
- A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
- A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
- A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
- A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.
