Answer: A. Brain - Organ level
B. Neurons - Cellular level
C. Neurotransmitters - Chemical level
D. Neurons and neuroglial cells - Tissue level
E.Brain combined with the spinal cord and spinal nerves - Organ System level
Explanation: There are five levels of organisation of life; cell, tissue, organ, system and organism.
The smallest unit is cell. Neurons are nerve cells.
Aggregation of cells forms a tissue. Neurons and neuroglial cells aggregate to form nervous tissues and are hence at tissue level.
Aggregation of tissues forms an organ. Brain is an example of organ. It is formed from aggregation of nervous tissues.
Tissues aggregate to form organs while aggregation of organs constitute a system. The nervous system consist of brain combined with spinal cord and spinal nerves.
The nervous system release chemicals called neurotransmitters.
Answer:
I believe that is the infraspinatus fascia
Answer:
<h2>consensus</h2>
Explanation:
Such type of the nucleotide sequence that is mostly present at each position is called a consensus sequence. This sequence plays an important role in the sequence alignment and some other molecular biological research and some other fields. Generally, it is made up of a small segment of the nucleotide and also considered as a conserved sequence motif because its presence is conserved on the position where it is present.
<h3>The answer is:</h3><h2>Hypothesis</h2>
A theory is an educated guess and so is a hypothesis. They both have limited evidence as a starting point for further investigation.
