Reforestation is a biodiversity method that can increase the biodiversity by replanting with trees. Reforestation will help forest recuperate from logging, rest fires and human abuse. Replanting trees will increase the density and variety of the trees and by doing so, wildlife will also increase. Although reforestation is a common approach to relive forest, forest management is still needed to maintain the endemic or native species.
This means that the fertilized egg has implanted in the fallopian tube and is growing outside of the uterus. An ectopic pregnancy occurs when the fertilized egg settles and grows in any location other than the inner lining of the uterus. Most of these cases occurs in the Fallopian tube (tubal pregnancy).

Answer:
b) Reptiles, birds, and some mammals produce amniote eggs.
Explanation:
All the mammals produce amniotic eggs. An amniotic egg is an egg that has four extraembryonic membranes including amnion. Amnion is a fluid-filled sac that serves as a cushion and does not allow the egg to desiccate. Since mammals are land animals, they have amniotic eggs to prevent any damage to the embryo from desiccation and physical injury.
