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>

<span>When the landmasses are again collected together in a specific area
The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent. </span>
Answer:
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’s response to its environment.

Explanation:
According to National Geographic, ostriches are a part of a very small group of birds that cannot fly because unlike most birds, their small wings are not strong enough to carry their body for flight and their breastbone isn't balanced enough for flying. Birds that are unable to fly are called ratites.
A number of scientists namely Thomas Huxley, Richard Owen, and others have tried to show that these ratites are actually related to each other and eventually, it was discovered that they all had one thing in common, the way the bones at the roof of the mouth were arranged was similar to that of reptiles rather than other birds.
Richard Owen found and assembled the remains of an extinct ostrich skeleton which was an extinct moa and contrary to already held opinion, one ratite known as tinamous did not really fit with the profile of a ratite because it could fly, even though almost grudgingly and they possessed keeled sternum which suggests that they evolved from flying birds.
DNA tests showed that tinamous evolved within ratites and not necessarily as a separate entity. The tests also showed that moas and tinamous are related.
It was also speculated that the division of the supercontinent Pangaea southern side led to the separation of flightless ratite ancestors, causing each landlocked group to evolve and become the flightless birds we know today such as the ostrich, rheas, etc.
