Answer: Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Explanation:
Both water and food. However the most obvious answer would be water.
The snowshoe rabbit will no longer be able to camouflage itself, thus resulting in a decline in its population due to death by predation.
What are abiotic factors?
Abiotic factors are nonliving components of an ecosystem, such as temperature, light, wind, and moisture. They are the physical and chemical elements of an environment that influence the structure and function of ecosystems. Abiotic factors shape the biotic, or living, components of an ecosystem, which include plants, animals, and microorganisms. Abiotic factors determine what species of life can live in a particular ecosystem. For example, a cold, wet climate will support different species of plants and animals than a hot, dry climate. Abiotic factors also determine the carrying capacity, or the number of organisms that can be supported, of a given environment. Abiotic factors are essential to the functioning of all ecosystems and are constantly changing due to natural processes and human activities.

Sponges are sessile animals that have specialized cells called amoebocytes and choanocytes.
Sponges (phylum Porifera) are one of the simpllest multicellular organisms (first to branch off the evolutionary tree from the common ancestor of all animals) that have bodies full of pores and channels allowing water to circulate through them. Sponges’ s structure consists of two thin layers of cells and mesohyl layer between them. They don’ t have real tissues or organ systems such as nervous, digestive or circulatory systems. Constant water flow through their openings and pores obtain food and oxygen and remove wastes.
