Biotic refers to the living factors and abiotic refers to the nonliving factors.
This is the chronicle of evolution over millions of years of geologic time engraved in the order which fossils appear in rock strata.
Answer:
cnidaria
Explanation:
the group contains jellyfish which fit that exact description tentacles that sting you with a burning sensation if your skin comes in contact with them
There are both physical and biological limiting factors found in nature.
-Physical factors (abiotic factors) include temperature, water availability, oxygen, salinity, light, food and nutrients.
-Biological factors (biotic factors) involve interactions between organisms such as predation, competition, parasitism and
herbivory.
Answer:
1.Plasma membrane
The plasma membrane surrounds the cell to create a barrier between the cytosol and the extracellular matrix. Plasma membranes also enclose lumens of some cellular organelles.
2.Endoplasmic reticulum
The endoplasmic reticulum (ER) is a large network of membranes responsible for the production of proteins, metabolism and transportation of lipids, and detoxification of poisons. There are two types of endoplasmic reticulum with separate functions: smooth endoplasmic reticulum and rough endoplasmic reticulum. The presence or absence of ribosomes in the ER’s plasma membrane determines whether it is classified as smooth or rough ER.
3.Golgi apparatus
The Golgi apparatus appears as a series of flattened, membranous sacs, or cisternae, that resemble a stack of pancakes just off the rough endoplasmic reticulum. It receives vesicles containing proteins recently produced by the rER. The Golgi apparatus can be compared to a warehouse or post office for newly formed proteins. Here the proteins are further modified, packaged, and sent off to their final destinations in the cell or body.
