1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.
2. Adaptation is an organism changing to better themselves in a certain environment.
3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.
4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.
5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.
7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
Answer:
The correct answer is B) the gravitational attraction that exists between all
bodies.
Explanation:
Every plant has a gravitational force which extends beyond its atmosphere.
The formula for calculating this gravitational pull is given as follows:
Fg= GMm/r2
= Force of Gravity
<em>G </em>= Gravitational Constant
<em>M </em>= Mass of the Planet
<em>m </em>= The Comets Mass
<em>r </em>= The distance between the centre of the comet and that of the planet
The force of gravity of the Planet can cause the comet to move faster in it's course towards the planet. This is called centripetal acceleration.
