Levels of organization in ecosystem: 1.Individuals or organisms <span>2.Population- A group of organisms of a given species that live in a specific area at a given time</span> <span>3.Comunity- All of the populations of different species that live in the same area and interact with one another</span> <span>4. Ecosystem- Community (biotic) interacting with the environment (abiotic)</span> <span>5.Biome- A group of ecosystems sharing similar characteristics</span> <span>6. <span>Biosphere-The sum of all the ecosystems established on planet Earth.</span></span>
<span><span>Species - a group of genetically related individuals that can breed to produce fertile young. The individuals are not necessarily members of the same species. </span><span> Population - a group of same species that interact with one another and reside in the same location.
</span><span>Community - a population comprised of different species that interact with one another and reside in the same location. </span><span> Ecosystem - includes all non-living aspects and the living population of the environment. It comprise both abiotic and biotic factors in the area. </span></span>
In what phase of cell division does exchange of genetic material between non-sister chromatids, or “crossing-over,” occur? It occurs in prophase 1 of meiosis
Explanation:
In prophase 1 of meiosis there is crossing of genetic material
Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Eukaryotic cells contain membrane-bound organelles, including a nucleus. So I belive the answer is A :P Hope it helps
