Weathering and erosion played a big role in forming the grand canyon. The rock was being weathered, most likely mechanical weathering, and then it eroded away. Think of a pebble that is in running water. When you pick it up, it is smooth, right. But before, it was pointy. So, the grand canyon was once a big rock, and weathering broke through it making it one of the wonders of the USA.
Answer:
Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.
Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
I believe it is 4)Shearing teeth (Carnassial teeth)
Amniotic egg are for reptiles
Fur are for marsupials, and dogs
Retractable claws are are cats
Shearing teeth are for carnivores
This is correct, because aerobic is more efficient than anaerobic, making it preferable. Cellular respiration is energetically more efficient than anaerobic respiration.
<h3>Cellular respiration and anaerobic respiration </h3>
Cellular respiration refers to the generation of energy in the form of ATP in presence of oxygen.
Conversely, anaerobic respiration generates energy (ATP) in absence of oxygen.
Cellular respiration is an energetically more efficient pathway than anaerobic respiration, thereby facultative organisms generate ATP by cellular respiration when it is possible.
