Bella is writing a research paper on ocean currents. The two sources she should consult will be;
1. an article published by a university or a government agency
3. an article published in 2015 and updated a week ago
Because while writing research papers we should consult authentic and latest information and resources.
Explanation:
In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.
Proteins are structural support molecules comprised of long chains of monomers called amino acids, joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source. Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding

A single motor neuron together with all the skeletal muscle fibers it innervates is called a motor unit.
- Motor neurons are more than just relays for the motor commands sent down the hierarchy from higher levels. They themselves are parts of intricate circuits that carry out extensive information processing.
- Due to their highly branching, intricate dendritic trees, motor neurons are able to integrate inputs from several other neurons and generate accurate outputs.
- A single motor neuron, and nothing else, innervates each and every muscle fiber (make sure you understand the difference between a muscle and a muscle fiber). However, several muscle fibers can be innervated by a single motor neuron.
- A motor unit is the aggregate of a single motor neuron and all of the muscle fibers that it innervates. The innervation ratio refers to how many fibers a motor unit innervates.
