Aerobic means "with oxygen," so when you exercise aerobically your body needs an extra supply of oxygen. Your heart has to work harder to continuously deliver the oxygen to your body, and this makes your heart stronger.

Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli al

Lorico [155]

Answer:

It provides more surface area for the absorption of oxygen.

Explanation:

The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

PLS ANSWER FASTTT What is the difference between Love waves and Rayleigh waves?

MAXImum [283]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{\text{Option D}}$

$\huge\textbf{Releigh Waves}$

A Rayleigh wave is a seismic surface wave causing the ground to shake in an elliptical motion(they move in a surafce rolling manner). A seismic wave means a earthquake wave, so Rayleigh wave is realted to the motion of earth and its crust. Rayleigh waves are formed when the particle vibrate with the combination of both transverse and longitudinal waves. This vibration gives rise to a wave which moves elliptically backwards that is Rayleigh Wave. Rayleigh waves are really fast they move with the spped 10 times faster than the speed of light. Rayleigh waves are generated by the interaction of P or compressional and S or shear waves(P ans S Waves are inside the Earths Crust) at the surface of the earth.

$\huge\textbf{Love Waves}$

Love waves or Q waves or Quer Waves are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. A Love wave is a surface wave having a horizontal motion only. Love waves are formed when the earth particles move in a transverse wave manner creating a wave travelling perpendicular to the direction the wave.

Masja [62]

Answer:

d. does not have the ability to develop into a new organism, but can give rise to any of the cell types in a body

Explanation:

they are referred to as master cells with the ability to make cells from all three basic body layers, so they can potentially produce any cell or tissue the body needs to repair itself.
