Answer 1
Answer:

Answer:

SAMPLE ANSWER:  The model does not represent a compound because it shows two atoms of the same element combined. To be a compound, the model would need to contain atoms of different elements, represented by different-colored balls.

On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.

Answers

The thyroid gland will be mostly affected in this case. The element Iodine is

the major precursor which is involved in the formation of two hormones.

Thyroid hormones

  • Triiodothyronine (T3)
  • Thyroxine (T4).

When an individual is exposed to radioactive iodine , it alters the production

of the hormones which leads to series of effects such as:

  • Decreased metabolism
  • Low body weight
  • Goitre etc.

Answer:

In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.  

However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.  

Why is only 10% of the energy consumed by an organism available to be transferred to another trophic level?

Answers

Final answer:

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer.


Explanation:

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer. This is known as the 10% rule.

The 10% rule states that energy is lost as heat during the process of respiration and metabolic activities, and only a fraction of the remaining energy is converted into biomass that is available as food for the next trophic level.

For example, if a primary producer (such as a plant) has 1,000 units of energy, only 100 units are passed on to the primary consumer (herbivore), and only 10 units are transferred to the secondary consumer (carnivore) in the next trophic level.

How long does nuclear waste need to be safely stored until it’s no longer hazardous

Answers

Nuclear waste:

Atomic waste is one of the most troublesome sorts of waste to oversee on the grounds that it is profoundly dangerous. As indicated by the U.S. Ecological Protection Agency (EPA), atomic waste is arranged into six general classes.

[1-2] These incorporate (1) spent atomic fuel from atomic reactors, (2) uranium factory tailings from mining and processing of uranium mineral, (3) significant level waste from spent atomic fuel reprocessing, (4) low-level waste, (5) transuranic waste from guard projects, and (6) normally happening and quickening agent created radioactive materials.  

The well-being concerns and security issues related with atomic waste present significant limitations on the far reaching utilization of atomic vitality. Because of its b and exceptionally perilous properties, atomic waste is required to be deliberately put away or reprocessed. The putting away and reprocessing are additionally convoluted by the long half existence of the radioactive materials in the atomic waste.

For instance, a portion of the segments can remain half of their hazardous levels even one million years after the fact after generation.

This is a process where two nuclei or particles interact to form different particles

Answers

Answer:

Nuclear Reaction

Explanation:

When two nuclei or particles move towards each other and, despite the Coulomb repulsion, they get close enough that there is interaction between the particles of one with the particles of the other by the nuclear force, and the formation of different particles and a redistribution of nucleons and a nuclear reaction is said to have occurred.

Nuclear reactions are usually produced by bombarding a target nucleus with a projectile that may be some type of particle or small nucleus, so that Coulomb's repulsion does not become a major obstacle. Reactions involving not very large energies occur in two phases. In the first phase, the target nucleus and the projectile group together, forming what is called a compound nucleus in a highly excited state. In the second phase, the composite core decays by any process that does not violate the conservation principles

In nuclear physics, a nuclear reaction is a process in which two nuclei or nuclear particles collide, to produce different products than the initial particles. In principle a reaction can involve more than two particles colliding,
