Answer:
True
Explanation:
The crust makes up less than 1% of earths mass.
Answer: The kinetic energy of the flying bird is 56 Joules.
Explanation:
Mass of the bird = 7 kg
Velocity of the flying bird = 4 m/s
Kinetic energy of the bird will be given by :


The kinetic energy of the flying bird is 56 Joules.
False. It can and will dissolve in water.

A) This is predator-prey relationship.
B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.
- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.
C) Let population A be Zebras, and population B Lions.
From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.
