=300000×510
=153000000Km

There would be dead animals overloading the Earth. Think about it, without worms and other things that break down dead things they would still be here and just sit there.
Work done= <span>force x distance moved in the direction of that force so: 200 x 15 = 3000J=4kJ</span>
The solution is hypotonic. This is because the solute concentration is greater inside the cell than outside the cell.
Answer and Explanation:
Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth
. The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting
. Even though fewer offspring are produced through this method, their survival rate is higher.
