Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them In this case, the eggs are fertilized inside the female's body before they are released.
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Explanation:
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.
Answer:
The mass of a pendulum's bob does not affect the period. Newton's second law can be used to explain this phenomenon. In F = m a, force is directly proportional to mass. As mass increases, so does the force on the pendulum, but acceleration remains the same.
