Answer:
because ots diffwrent feom the others, cause of the cells roles ir has to play.
I'm pretty sure the answer is B. Invest in alternative energy sources that do not burn fossil fuels. The reason I would pick B is because in Antarctica the ice is melting more and more over time because, cars and factors etc are burning fuels which result in more damage to the ozone layer.
Answer:
A pseudocoelom is a body cavity that lies between mesodermal and endodermal tissue and is, therefore, not completely surrounded by mesodermal tissue. A “true” coelom is completely surrounded by mesodermal tissue, and can thus be subdivided into compartments.
Explanation:
The cell's series of tunnel-like membranes functioning in transport and storage are the Endoplasmic Reticulum.
What are the functions of the Endoplasmic Reticulum?
In both plant and animal cells, the endoplasmic reticulum is a network of tubules and flattened sacs that perform a number of tasks.
The structure and function of the two ER regions are different. Ribosomes are affixed to the cytoplasmic side of the membrane in rough ER. Ribosomes are not linked to smooth ER. The smooth ER is often a tubular network, whereas the rough ER is a collection of flattened sacs.
Rough Endoplasmic Reticulum (RER)
Endoplasmic Reticulum in rough shape. Membranes and secretory proteins are produced in the rough endoplasmic reticulum. Protein synthesis is carried out by translation on the ribosomes affixed to the rough ER. The rough ER generates antibodies in certain leukocytes (white blood cells). The rough ER creates insulin in pancreatic cells.
Smooth Endoplasmic Reticulum (SER)
The production of carbohydrates and lipids is one of many tasks performed by the smooth ER. Cell membranes must be built using lipids like cholesterol and phospholipids. Vesicles that deliver ER goods to various locations also use Smooth ER as a transitory place.
Hence, the correct answer is the Endoplasmic reticulum.

Answer: They evolved from the same line as the cave bear, descending from Ursus abstrusus, a small, primitive black bear. Ursus Euarctos, a black bear, came to North America during the Pliocene Epoch before the brown bear.
