Answer:
Membrane bound cell organelles
Explanation:
A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.
To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.
Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.
Answer:
Explanation:
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA. These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and the phosphate groups that are linked by different bonds in a series of sequences. The DNA structure defines the basic genetic makeup of our body.
