Answer:
Phospholipid bilayer and carbohydrates.
Explanation:
Phospholipids form a double layer that protects the cell from the outside, in this layer the heads of the phospholipids, which are hydrophilic, are orientated towards the inside and the outside of the cell, and the tails of the two layers, which are hydrophobic, are in contact with each other. This bilayer allows the passage of certain substances due to its polarity, the elements that are too big, are ions, or that are hydrophilic have especial channels made of proteins that allow the passage of these kinds of elements
The other component that can affect the permeability is carbohydrates. These, when they attach to lipids and proteins, form a layer around the cell that allows the passage of certain substances, allows the recognition of the cells that are from the body, and the ones that are foreign so that there can be communication between cells.

Answer: N-terminal green fluorescent protein (GFP)
Explanation:
Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. <u>The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid</u>.
Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.
<u>GFP is Green Fluorescent Protein</u>, and it is a protein produced by the jellyfish <em>Aequorea victoria</em> t<u>hat emits bioluminescence in the green region of the visible spectrum</u>. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. <u>Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.</u>
There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.
The symptom that is a characteristic of manic mood state is therefore: b) Catatonic excitement
<h3>What is the Manic Mood State?</h3>
The manic mood state is a phase of bipolar disorder, which is characterized by catatonic symptoms such as heightened energy, euphoria, loss of sleep, excessive talk, and being hyperactive.
Thus, the symptom that is a characteristic of manic mood state is therefore: b) Catatonic excitement
