What are the rules of atoms?

Biology
1 answer:
liberstina [14]3 years ago
6 0

The rules of the atoms can be majorly explained through three rules and principles;

  • Aufbau principle
  • Pauli exclusion principle
  • Hund's rule

Hund’s rule states that an atomic orbital is firstly singly occupied by electrons before it is doubly occupied until its fully filled. Electrons in a singly occupied orbital have the same spin quantum number.

Aufbau principle states that the lowest atomic orbitals are occupied first, while Pauli exclusion principle states that the electrons in an atomic orbital cannot have the same quantum state.

Which of the following does not characterize the lungs of birds?
kompoz [17]

Answer:

C) They are compressed during inhalation.

Explanation:

Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.

In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.

In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.

How do radiation and chemotherapy affect cancer cells?
elixir [45]

Answer:

They destroy the DNA or RNA

Explanation:

Cancer drugs work by damaging the RNA or DNA. The faster the cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.
