How can a molecule that contains an atom of phosphorus be made radioactive using an unstable isotope?

Biology
1 answer:
AVprozaik [17]2 years ago
3 0

Answer:

A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule

Explanation:

Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.

However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.

This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.

Answer:

People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.

Crude oil is ________. a. composed of less than ten different hydrocarbon molecules b. usable in its raw form c. formed in a wid
kolbaska11 [484]

Crude oil is <u>refined to separate the chemicals used for gasoline, lubricants, plastics, and other products.</u>

<u />

  • In a distillation tower, the crude oil is separated by boiling point after being heated by a furnace.
  • The material is then transformed into finished goods like fuels like gasoline and diesel, as well as specialty items like asphalt and solvents, by using heat, pressure, or a catalyst.
  • Ethane, liquid petroleum gas (LPG), and naphtha are the three main petrochemical feedstocks generated from crude oil.
  • These are mostly employed in the creation of synthetic fibers, plastic polymers, and other petrochemical intermediates.
  • With increased global income, demand for these products will only continue to rise.

Both homologous and analogous structures are strong pieces of evidence of evolution.
Hunter-Best [27]

Answer:

A - True

Explanation:

Summary. Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
