<span>The thymus.The thymus plays an important role in the development of T-lymphocytes which is an important type of white blood cell. It reaches maximum development at puberty and then the thymus begins to get atrophied (the shrinking of the thymus with age) and then the thymic stroma is replaced by fat tissue. Loss of thymic function is thought to contribute to weaker immune system of the elderly, increasing instances of diseases such as cancers and other infections.</span>

ANSWERS:

They are both ionic compounds.

These compounds are made up of H^{+} cations (positively-charged ion) and either NO_{3}^- or SO_{4}^{-} anions (negatively-charged ions).

Their names both end in -ic acid.

Acids are named based on their anion. With acids like these where the anion is attached to a hydrogen cation, we name such acids with the the suffix “-ic”.

They both contain polyatomic ionic.

NO_{3}^- and SO_{4}^{-} are both polyatomic ions.

"Poly-" = many

"ions" = have a + or - charge

So, yes, these are ions that are made up of several atoms (not just one atom like H^{+})

Sound waves travel through gas liquid and solids A) True B) False
Novay_Z [31]

Answer:

True.

Explanation:

  • Sound is a form of Energy that produces a sensation of hearing in our ears.
  • Sound is produced as a result of vibration produced in a body.
  • Sound energy is transmitted from one place o other place by wave motion.
  • When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
  • During vibration, they collide with the surrounding particle and transfer some energy to them.
  • They then start vibrating faster and transferring  energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
  • Thus, particles are an important factor in propagation of sound.
  • Sound cannot travel in vacuum.
  • It requires a medium to travel from one point to another.
  • A sound can travel in all medium, solids, liquids and gases as all of these have particles.
  • The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest  in solids.
