Answer 1

Answer:

Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow. ... The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures

Explanation:

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.
