Explanation:
Answer:
Neuroglia - the supporting cells of the nervous system
Oligodendrocytes - fewer branches than astrocytes
Dendrites - branched extensions off of a neuron
Astrocytes - star-shaped cells
Microglia - small, phagocytic cells in the central nervous system
Explanation:
The given cells in the question are cells of different types of neuroglial cells that are astrocytes, microglia, oligodendrocytes are different types of neuroglial cells. The nervous systems are supported by this Neuroglia.
As the name indicates Astrocytes are star-shaped cells and carry many branches whereas, Dendrites are the smaller, but higher in numbers, projections of the neuron cell body. It has also axon projection bind to the cell body.
• Microglia are phagocytic cells that protects thenervous system
Answer:The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.

Answer:
C. a dog buries a bone in the backyard
Explanation:
A dog burying a bone in the backyard is not an observation in terms of scientific methods.
Observation is the process of acquiring data about a phenomenon under study.
Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.
Also, we can use some specialized equipment to make observations.
- A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.
