46 chromosomes, but 23 pairs.
Explanation:
1.Law of Inertia
<em>Inertia</em><em> </em>: is the ability to resist change in motion.
<em>Example</em><em>;</em><em> </em><em>if you roll a ball it will keep running unless you</em><em> change </em><em>it's</em><em> </em><em>direction with the help of </em><em>friction.</em><em>.</em>
2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..
<em>unbalanced force is a type of force</em><em> where total force</em><em>≠</em><em>zero</em><em>,</em><em> </em><em>means the object will move</em><em>.</em><em>.</em>
<em>Example</em><em>;</em><em> if you will try to push a truck</em><em> will be less but if you push a car the acceleration will be more</em><em>.</em><em>.</em><em> because </em><em>c</em><em>ar has less </em><em>mass.</em><em>.</em>
<em>3</em><em>.</em><em> the third law of motion state that foreign every</em><em> action there is a opposite reaction</em><em>.</em><em>.</em>
<em>Example</em><em>;</em><em> can you throw a ball on the floor </em><em>.</em><em>.</em><em>.</em><em>the floor </em><em>pushes</em><em> </em><em>back</em><em> that the ball</em><em>.</em><em>.</em>

I think if the whale population decreased the surface fish populations would decline due to reduced populations of algae. This can be simply explained by the fact that, if the whale population is decreased, it means that the nitrogen rich feces that is supply nutrients to the algae would also decrease and therefore decrease the population of the algae and as a result the population of of the surface fish would also decline.
