Where is the DNA located in a Prokaryote cell and Eukaryotic cell?

tigry1 [53]

Prokaryotes have no cell nucleus and no membrane enclosed organelles. Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like). In other words, the nucleoid is the area in a prokaryotic cell where DNA is located.

In eukaryotic cells, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.

How will biodiversity change if a new bird species ate small mammals lizards and toads

Karolina [17]

Answer:

Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.
