Explanation:
Transmembrane protein are proteins that are firmly associated with membranes because it is integrated along the length of bilayer lipid membrane. This kind of protein is made up of two kinds of amino acid, hydrophilic or polar amino acid and hydrophobic or non polar amino acid. while peripheral protein loosely associated with membrane, they are present on the surface which means they are not integrated in to the cell membrane and facing intercellular fluid. this is why it contains only hydrophilic amino acid.
The primary amino acid sequence contains hydrophobic amino acid which identifies the protein as transmembrane protein. These amino acid are methionine (Met), leucine(Leu), valine(Val), glycine(Gly), tryptophan(Trp), isoleucine(Ile), phenylalanine(Phe), proline(Pro) and alanine(Ala)
The given question is not complete. The complete question is:
Number the steps from when a stimulus is received to when the body reacts.
The stimulus is received by sensory receptors.
Motor neurons cause muscles to contract so the body can react to the stimulus.
The brain processes the information through interneurons.
Interneurons transfer response information to motor neurons.
Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The body of an organism like humans reacts towards each of the external stimuli of the environment like the smell of the food and even to the internal stimulus like hunger or pain. Thus, it can be considered that one is stimulated all the time and reacts towards the constituents found in the surroundings. The entire procedure of the organism reacting towards the stimuli are as follows:
1. The sensory receptors receive the stimulus.
2. The stimulus information is further carried to the spinal cord or the brain by the sensory neurons.
3. The processing of the information in the brain takes place with the assistance of interneurons.
4. After that the response information is mediated towards the motor neurons by the interneurons.
5. The motor neurons eventually result in the contraction of muscles showing that the body is reacting towards the stimulus.
Smaller molecules diffuse easily as compared to the larger molecules. In other words, smaller is the size of molecule, easier and faster is its diffusion across a semipermeable membrane.

The cells that are transformed into plasma cells with the influence of cytokines are T-Helper cells. It is a very important cell in our immune system and it is used to activate antibodies that could help destroy microbes and pathogens entering the body. They are commonly produced in the bone marrow.
