Answer:
hormone that causes fight or flight: adrenaline
Energy from a light source is known as radiation.
Answer:
Mass = 15600 g
Explanation:
Given data:
Number of atoms of oxygen = 5.87 × 10²⁶
Mass of oxygen = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5.87 × 10²⁶ atom × 1 mole / 6.022 × 10²³ atom
0.975 × 10³ mole
975 mole
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 975 × 16 g/mol
Mass = 15600 g
Dimensional analysis:
5.87 × 10²⁶ atom × 1 mol/6.022 × 10²³ atom × 16 g/ 1 mol = 15600 g
Answer:
Option A, Tectonic plates above the currents move toward each other.
Option C, One plate will submerge beneath another plate.
Option D, A convergent boundary is formed at the site of the collision.
Explanation:
The convection currents are the ones responsible for the movement of the tectonic plates, thus shaping the Earth's appearance with their movement, as well with the structures created by the movement. If the convection currents move toward each other, than the tectonic plates are moving toward each other. That will cause collision between the continents, and convergent boundaries will be formed. If the collision is between two or more continental plates, than they will merge, and from the pressure mountain ranges will start to form, but if there an oceanic plate involved as well, than the oceanic plate will be subducting beneath the continental plate or plates.
