After studying the diagram you have posted above that represents the electric field. The sign of the new charge on both A and B is that A is going to be negative and that B is going to be negative. So the correct answer choice is 3.
These cells line focal pits of the CNS and, in specific spots, deliver CSF. The cilia of these cells help flow the CSF that sustains and pads the mind and spinal string. Expansions from these cells wrap vessels and give additional control over which materials enter or leave the intercellular liquid of the CNS.
Prophase I : Condensation of chromosomes and nuclear envelop breakdowns.
Metaphase I : Pairing of homologous chromosomes and chromosomes line on metaphase plate.
Anaphase I : Homologous pair chromosomes separate and move opposite sides.
Telophase I : Chromosomes reach spindle poles.
Cytokinesis : Division of cytoplasm, division of cell takes place.

I can not guarantee that this is correct, but it is my answer to your question.</span>
Enzyme synthesis cannot be a function performed by a membrane protein.
<u>Explanation:</u>
Membrane protein is found on the lipid bilayer that surrounds the cell. Enzymes are the globular structures of proteins which are made by the translation of the specific m-RNA in the cytosol of the cell and not by the membrane proteins. While a membrane protein can be used as a pump to transport ions across the membrane, it can be used for cell-cell or cell-matrix adhesion and as a hormone binding protein.
