Len [333]

Answer:

The dry-out material contains spores of anthrax-causing bacteria

Explanation:

<em>Anthrax is a disease caused by a bacteria known as Bacillus anthracis. Susceptible animals get infected by anthrax when the spore of the bacteria gets into their bodies, become activated, multiply and produce toxins.</em>

The spore serves primarily as a propagating structure and also as an agent for transmitting infections. It can be transmitted by air, water, food or any other means. Bacterial spores usually have the capability to tolerate harsh environmental conditions and only become inactivated when conditions are favourable.

The dry granular powdery material constituent of the letters received by the U.S. senators must have been spores of <em>Bacillus anthrasis</em>

Answer:

Varicella-zoster virus

Explanation:

Varicella-zoster virus (VZV) is a virus with double-stranded DNA as its genome. It is a member of the family Herpesviridae. The virus causes chickenpox in children. It is mostly present in the latent form after the disease subsides and the same virus can cause shingles in adults under specific conditions. Therefore, shingles is also called a reactivated form of chickenpox caused by the latent varicella-zoster virus. The virus has an incubation period of 10 to 23 days and causes the formation of pus-filled small vesicles on the face or upper trunk.

What are the two main ways a star can live based on it mass?
Andrej [43]

Answer:

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.

Stars start their lives as clouds of dust and gas. Gravity draws these clouds together. A small protostar forms, powered by the collapsing material. Protostars often form in densely packed clouds of gas and can be challenging to detect.

"Nature doesn't form stars in isolation," Mark Morris, of the University of California at Los Angeles (UCLS), said in a statement. "It forms them in clusters, out of natal clouds that collapse under their own gravity."

Smaller bodies — with less than 0.08 the sun's mass — cannot reach the stage of nuclear fusion at their core. Instead, they become brown dwarfs, stars that never ignite. But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. The star turns on and becomes a main sequence star, powered by hydrogen fusion. Fusion produces an outward pressure that balances with the inward pressure caused by gravity, stabilizing the star.

How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years. A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years. (This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time.)
