An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
new species will take their place
Explanation:
The frontier ethic assumes that saving endangered animal species may be considered foolish because new species will take their place. Frontier ethics suggests that the earth has an unlimited wealth of resources.
- The theory counters the sustainable ethics view to utilization of resources.
- Frontier ethics believes that if a resource becomes depleted in a part of the world, the earth will produce new ones to balance up.
- This is not economic or sustainable view to use of resources.

Human impacts on biomes are best characterized by interruption of natural biome process.
<h3>What is a Biome?</h3>
An area of the globe that may be categorized based on the kind of plants and animals that inhabit there is known as a biome. What life there is in a biome depends on factors like temperature, soil, light, and water availability.
An ecosystem is distinct from a biome. An ecosystem is a habitat where living and nonliving things coexist. A biome is a particular geographical region distinguished by the organisms that call it home. Many different ecosystems can make up a biome. For instance, habitats like coral reefs and kelp forests can be found in aquatic biomes.
