Answer:
D
Explanation:
An oil boom helps contain the oil so that it is easier for them to skim it off of the water. They aren't meant to clean up oil, only to contain the oil since it does not sink or mix with water.
The shape of a protein allows it to perform its particular job.
Answer:
T-tubules (transverse tubules)
Explanation:
T-tubules, also known as transverse tubules, are narrow tubes that are continuous with the sarcolemma (i.e., the cell membrane of striated muscle cells). In skeletal/cardiac muscle cells, T-tubules form invaginations of the sarcolemma that contain many ion channels involved in excitation-contraction (e-c) coupling of muscle cells. Thus, transverse tubules function to conduct the action potential from the cell membrane (sarcolemma) to the interior of the muscle cell.
Answer:
As these cells are non-photosynthetic, all other organelles would be found in these cells except for chloroplasts which contain photosynthetic pigments used for photosynthesis. A few examples of structures found within these cells would be cell wall, cell membrane, cytoplasm, ribosomes, nucleoloid and many others. Do note that prokaryotic cells do not have organelles with membranes hence they do not have mitochondria or lysosomes or endoplasmic reticulum etc.
