Motor neurons are cells that carry information from the central nervous system to the muscles and glands, while sensory neurons send signals from body parts to the central nervous system. Sensory neurons are found over the body, such as in the skin, ears, eyes, nose and tongue. Interneurons in the central nervous system allow information to flow between motor and sensory neurons.
he cell body of a neuron holds a nucleus and organelles that carry out basic cell functions, such as protein synthesis, transporting materials and producing energy. A neuron also has special parts that allow information to move. Dendrites are branch-like structures that receive signals. The axon, which often resembles a long tail, takes messages away from the cell. The axon ends in a terminal containing a chemical called a neurotransmitter, which allows the signal to move across the space between the cell that sends information and the cell that receives it. When axons and dendrites of different cells are bunched together, they create nerves. Ganglia are groupings of many neurons' cell bodies.
The processes conducted by nerve cells happen incredibly fast, in thousandths of a second. That is why the human body reacts so quickly to stimuli in the environment. A hand touching a hot stove is removed almost immediately so that serious injury does not occur.

Explanation:
Like we all know, the purine ring of IMP is made up of a nine membered compound . they are heterocyclic aromatic organic compound that consist of a pyrimidine ring fused to an imidazole ring. there are four nitrogen atoms and five carbon atom.
The ring is imidazole ring is made up of N1, C2, N3, C4, C5, C6 with the pyrimidine sharing C4 and C5 with the imidazole ring and also made up of N7, C8, N9.
the direct source of N1 is from aspartate
the direct source of C2 and C8 is from N 10 ‑formyltetrahydrofolate (THF)
N3 and N9 is derived from the amide group of Glutamine
C4, C5 and N7 is derivd from Glycine
C6 is derived from bicarbonate
Answer:
Explanation:
A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they form a double layer that is characteristic of all cell membranes.
A phospholipid is made up of two fatty acid tails and a phosphate group head. Fatty acids are long chains that are mostly made up of hydrogen and carbon, while phosphate groups consist of a phosphorus molecule with four oxygen molecules attached. These two components of the phospholipid are connected via a third molecule, glycerol.
Answer: first photo in my opinion would be d or c, but mostly d!
2nd photo would be either a!
hope i helped!
