There are (2) DNA molecules.
The cities, especially the largest ones have almost always been located along the banks of a river, usually a larger one. ... In the past, a major reason was the fertile soil, as the larger population needed more food, and the fertile deposits by the rivers enable high scale production of food. ( cite: google )

Answer: Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Examples of transverse waves include vibrations on a string and ripples on the surface of water. We can make a horizontal transverse wave by moving the slinky vertically up and down. In a longitudinal wave the particles are displaced parallel to the direction the wave travels. brainliest??
Explanation:
Answer:
120 mm Hg
Explanation:
Given that,
Height = 8022 ft/2445 m
Atmospheric pressure = 570 mm Hg
In order to calculate the partial pressure of oxygen, at first, it is required to calculate the mole fraction of Oxygen.
Mole fraction of Oxygen = % of Oxygen in the air
= 20.95 % = 0.2095
Now, we know that,
⇒ Partial pressure of oxygen = Total pressure × mole fraction of Oxygen
= 570 × 0.2095
= 119.415 mm Hg
Therefore, the partial pressure of oxygen in Vail is approximately 120 mm Hg.
