Answer:
A motor unit is a group of MOTOR NEURON and the MUSCLE FIBERS connected to it.
Explanation:
Neuron is the structural and functional unit of nervous system.
Motor unit consists of a motor neuron and the skeletal muscles innervated by the terminals of the neuron.
Several associated motor units called motor pool coordinates together the contractions of a single muscle.
That is, the activation of a motor unit leads to the contraction of all the muscle fibers attached to it.
I think that occurrence is an example of : The lithosphere influences the atmosphere and biosphere
Rains happen when the water within the atmosphere brought out by the win and will eventually fall to the place where it came into
The thing is, These mountains often blocked the water-filled with air, causing it not able to reach the place behind the mountain, which will eventually became a desert
Answer:
1. Nucleotides
2. Amino acids
3. Amino acids
4. Glucose
Explanation:
All the above substance described are biomolecules. They are all polymers i.e. complex molecule bond together in a long repeating chain, made up of simpler subunits called monomers. The monomers of the different biomolecules outlined above are:
1. The nucleic acids, DNA and RNA carry genetic information and are made up of many NUCELEOTIDES. A nuceleotide is a chemical combination of a five carbon sugar (pentose), phosphate group and nitrogenous base. These nucleotides are arranged sequentially to form nucleic acids (RNA and DNA).
2. Myoglobin is a protein that binds oxygen molecules and is a polymer of AMINO ACIDS. Amino acids are the building blocks of proteins. They are arranged to form a 3D structure that determines the function of the protein.
3. Insulin is a protein hormone that regulates blood glucose levels and is a polymer of AMINO ACIDS. All proteins are made up of the amino acid but the protein's function is dependent on the 3D structure formed by the amino acid sequence.
4. Animals store energy in the form of glycogen, a carbohydrate made up of thousands of monosaccharide (GLUCOSE). Glycogen is a polysaccharide made up of many monosaccharide units. These units are glucose molecules that are multibranched to form the glycogen that stores mainly in the liver and muscles of animals.

Answer:
Multiple RODS send combined messages to a bipolar cell, whereas a single _CONE may link directly to a single bipolar cell.
Explanation:
The rods and cone cell are photoreceptive cells in the eye. The Rod cells are sensitive to coloured lights stimulus, while the Cones cells are sensitive to black and white stimulus.
