Answer:

Hi,

They form from thunderstorm when moist air and cool dry air masses meet to create instability in the atmosphere and due to change in wind speed and direction at high altitudes the air swirl horizontally to form a funnel that progress to touch the ground and become the Tornado.

Explanation

First,a large thunderstorm occurs in a cumulonimbus cloud. A change in wind direction and speed occurring at high altitude will result into the swirling of air horizontally. The rising air from the ground will push up on this swirling air and tips it over. A funnel made up of warm air starts to suck up more warm air from the ground and surroundings thus growing longer and it stretches to reach the ground. When the funnel touches the ground, the tornado is formed.

Best wishes!

Answer:

Most tornadoes form from thunderstorms. You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada. When these two air masses meet, they create instability in the atmosphere. ... Most strong and violent tornadoes form within this area of strong rotation.

Although coal is no longer the favored energy source, u.s. coal mines still produced close to a billion short tons of coal. deta

Dahasolnce [82]

Mineral coal: Occurs through the fossilization of plants and animals, these fossils are stored for years, allowing their decomposition through microorganisms and high temperature and pressure, to originate a carbon-rich material, coal. Mineral coal is the most widely available fossil fuel in the world and like all fossil fuels, burning it can release various harmful gases into the atmosphere, which can cause respiratory problems, acid rain and destruction of the ozone layer. Through this charcoal, peat can be produced, which is widely used in the identification of plant remains. Mineral coal burns easily, so it is necessary to adopt safety measures to prevent fires and burns.

Charcoal: This charcoal comes from the solid part of the dry wood. It is less polluting than coal, in addition to being cheaper and abundant, since it is a type of renewable energy. It also has great combustion capacity, so it needs preventive measures against fires and accidents. It is often used in medicinal products, but its consumption can lead to diarrhea, constipation and vomiting.

Bone charcoal: It originates in the calcification of animal bones. They are often used in oil refinement and as a black pigment in some products. It can also be used as an absorbent material and as a lightening agent for oils and sugars. It does not have such a high combustion capacity, and can be used in edible products, however the excess of this coal can modify the final structure of the products in which it participates.

Soot: is coal in powder form, originated from incomplete combustion of methane and ethylene. It can be used in the manufacture of paints, tires, absorbents and others. Burning it can release toxic products into the atmosphere and should therefore be avoided.

Activated carbon: It originates from the burning of some types of wood and is used to remove impurities from substances, being frequently used for water treatment. It can also be used as an antidote to animal poisoning. Its use should be done according to the recommended amount, to prevent possible poisoning from occurring.

T-G-A-G-G-T-C-T-C-C-T-C T-G-A-G-G-T-C-A-C-C-T-C What type of mutation is depicted in this sequence?

kap26 [50]

Answer: The mutation is substitution.

Explanation:

There are three main types of mutation:

Substitution, deletion, and insertion.

We would be able to tell right away if the second sequence had an insertion or deletion, because it would have a different number of letters than first sequence. However, it does not. Both sequences have 12 letters.

But, the 8th letter in the first sequence (T) is different from the 8th letter in the second sequence (A).

This is substitution.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or r

sdas [7]

Answer:

um...

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

A stem cell is fate determined once it has received the Self Renewal signal. As result, which genes are newly expressed?

zhuklara [117]

Answer:

The genes that are newly expressed after the stem cell has received the Self Renewal signal are: ID genes, DET genes and DIV genes.

Explanation:

Stem cells have the capacity of turning into different types of cells according to the needs of the tissue they're in. When these genes are expressed, the stem cell loses this potential.
