Answer:

1. Nearly all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium.   In what is called radioactive emission of "alpha particles" the atom of, say uranium, spits out particles in the form of two protons and two neutrons--a helium nucleus.

2.Helium is obtained through natural gas as it is extracted from the ground. The helium is a result of the decay of thorium and uranium. As these elements decay, they release an alpha particle. That alpha particle is the nucleus of a helium atom.

3.Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.

Answer:

1. A natural rare element on Earth. It is naturally found  on the Earths ground.

2. Helium is obtained from decaying radioactive elements such as Uranium, and/or by liquefying air in order to separate the different elements.

3. It depends on the scale needed. For large use the processes of fractional distillation is used, this process separates liquids based on their boiling points. It can also be obtained from decaying radioactive elements.

Explanation:

Helium is a natural colorless gas that is naturally found on Earth's grounds. It was discovered by astronomers Pierre Janssen and Sir Joseph Lockyer  in 1868 . It has a low density, chemical reactivity, low temperature, and boiling point. This gas is used for a number of things including:

  • Airbags
  • MRI magnets
  • Computer and mobile phone chips

How can bacteriophage dna be spread from cell to cell without causing cell death?
nexus9112 [7]

Answer:

through lysogenic cycle

Explanation:

The bacteriophage attaches itself on the bacterial surface. The DNA strand to be replicated is injected into the bacteria by the bacteriophage. The DNA integrates into the bacterial chromosome and  becomes a pro-phage.

The bacterial cell proceeds to cell division  through budding. The progeny possess the bacteriophage. After complete replication, the virus DNA  detaches from the host genome and enters the lytic cycle. The capsid heads assemble on the surface of bacterial cell to package the fully matured viral DNA . The phage produces lytic enzymes that weaken the cell wall of bacteria cell.

Compare and contrast dehydration synthesis(condesation) and hydrolysis.
dexar [7]

Answer:

This

Explanation:

In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.Aug 14, 2020
