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.
The main function of the nematocyst is prey capture. The correct option among all the options given in the question is option "B". The nematocysts are used by Cnidarians like hydra, jellyfish etc. It is actually a specialized capsule that contains venom and it is used to paralyze and capture small preys for food and also to sting any enemy that comes near.
Answer:
Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called the stomata. The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf.
Explanation:
Answer:
D. It produces gametes / sex cells.
Explanation:
Meiosis is a reductions division, so the source of the sex cells will produce the gametes, undergoing meiosis. The gametes will have half the number of chromosomes in a human body (23).
