. As arteries extend outward they decrease in thickness until they turn into microscopic vessels known as_ ((frog dissection))
sveticcg [70]

ANSWER: The correct answer is CAPILLARIES

EXPLANATION: Arteries are the muscular wall tube that carries oxygenated blood from the heart to other part of the body. The arteries extend outward from the heart, and form capillaries.

The capillaries are hairlike thinnest blood vessels, that helps to join the arteries and ventricles together. The blood in the arteries extends to the capillaries of the organs where the blood is supplied, and then moves out to from the organ via the ventricles.

The capillary starts from the part of the arteries that are very thin.

In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.

Monica [59]

Answer:

West Nile virus (WNV) causes epidemics of febrile illness, meningitis, encephalitis, and flaccid paralysis. Since it was first detected in New York City in 1999, and through 2004, 16,000 WNV disease cases have been reported in the United States. Over the past 5 years, research on WNV disease has expanded rapidly. This review highlights new information regarding the virology, clinical manifestations, and pathology of WNV disease, which will provide a new platform for further research into diagnosis, treatment, and possible prevention of WNV through vaccination.
