<span>The dominant motion in the universe is the smooth expansion known as Hubble's Law. In 1929, Hubble estimated the value of the expansion factor, now called the Hubble constant, to be about 500 km/sec/Mpc.</span>
I think it’s called a hawk
The answer is.d. stromatolites hope it help
<h2>Endothermic Process</h2>
Explanation:
An example of endothermic process is :
Heat is needed for water to boil.
Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.
Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.
I believe your answer would be the stem.
