The correct answer is option C. Single celled organisms and soft, bone less animals. The Precambrian ear was believed to be before evolution. Meaning more plants and complex animals. Therefore, organisms were single celled during that time.

Answer: A mollusk accidentally imported from Europe. They clog pipes and water ways.
Explanation:
Answer:
It has no atmosphere.
Its surface is covered with circular craters.
It has huge, round basins.
It has lunar highlands.
Explanation:
Mercury is similar to the moon because both have no atmosphere, surface is covered with circular craters and having large, round basins. Both have lunar highlands. Craters are the circular, excavated holes made by impact events that has a rough surface while on the other hands, most of the crust of the Moon is made of silicate rocks is known as anorthosites, these regions are called the lunar highlands.
Answer:
The best answers to your question, as per the immense amount of research on the topic, would be: The peptides that you would expect to find in the polypeptide that will eventually fold to become an ion channel protein, would be: 1. A signal-anchor peptide, 2. an internal signal peptide and an amino-terminal signal peptide.
Explanation:
Ion channels are transmembrane proteins whose main purpose is to serve as pathways through which different ions, like potassium, or sodium, can cross from both the inside and outside of the cell as it may be required in different circumstances. These proteins, unlike many others, are first translated from genetic material in the cytosol, and then, thanks to signaling sequences on their chain, they will be taken to the ER and Golgi apparatus, where the rest of the translation and the final packaging will be arranged, so that they may be shipped towards their destination, which is the plasma membrane. These proteins, because of their function, need to have a signal-anchor peptide, an internal signal peptide which will direct them to the ER for final assembly and packaging and an amino-terminal signal peptide.
