The respiratory system of the birds
On the left side there are 12 hydrogen atoms there needs to be the same number on the right. The coefficient for hydrogen in water is 2.
2*x=12
x=6
Law of Motion says that every object that moves uniformly tends to stay in that state unless a force is applied to it. Force is equal to the mass of that object multiplied by its acceleration:
F = m × a
The unit of force is N = kg * m/s².
Q1: T<span>he acceleration of gravity on Planet Zorg is unknown:
a = ?
</span>We know:
F = 180 N
<span>m = 30 kg
</span><span>
Since F = m </span>× a, then:
a = F/m
a = 180 N/30kg
a = 180 kg*m/s² / 30 kg
a = 6 m/s².
So, the acceleration of gravity on Planet Zorg is <span>6 m/s².
Q2: Force needed to change the motion of the object on the Earth is unknown:
F = ?
We know:
a = 9.8 </span><span>m/s²
m = 30 kg
If F = m </span>× a, then:
F = 30 kg × 9.8 m/s²
F = 294 N
So, f<span>orce needed to change the motion of the object on the Earth is 294 N.</span>
Adaptation is supported by Darwin's observation of local
variation among tortoises in the Galapagos Islands.
<span>In biology, an </span>adaptation, also called an adaptive trait, is a trait with a
current functional role in the life of an organism that is maintained and
evolved by means of natural selection. Adaptation<span> refers
to both the current state of being </span>adapted<span> and
to the dynamic evolutionary process that leads to the </span>adaptation.

Answer:
The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite.
Explanation:
Generally light colored, coarse-grained plutons of these compositions are referred to as granitoids. The term originated from Pluto, the classical god of the underworld.
