Gray matter consists of the ______ of neurons

Biology
2 answers:
laila [671]3 years ago

Gray matter consists of the <u>unmyelinated axons</u> of neurons.

<u>Explanation:</u>

The outer layer of the brain consists of the grey matter and white matter. The grey matter gets its name by the pinkish grey colour obtained by the greyish colour of the neurons and the red colour from the capillaries.

The grey matter consists of the dentrites, axons and cell bodies and this is essential for memory, attention and learning.  

The unmyelinated axons are not covered by the fat protein myelin and these axons carry signals.They are the ones to help the processing of information in the brain.

Gray matter consists of the <u>cell bodies </u>(soma) and <u>dendrites</u> (branches) of neurons or the nerve cells.  

Explanation

The absence of myelinated sheaths of the neurons in gray matter gives its gray color. Along with soma and dendrites, gray matter also consists of axon tracts, neuropil, glial cells and blood capillaries. The volume of gray cells correlates with a person’s skills and abilities.

Both the brain and the spinal cord contains gray matter. Gray matter is involved in a number of brain activities like thinking and memory, seeing and hearing, decision making and self-control etc.

What is a secure chemical landfill? A. a landfill in an area of nonporous bedrock B. a biological treatment plant for liquid was
natima [27]

The correct answer is option A, that is, a landfill in the region of nonporous bedrock.  

A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.

A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.

Explain the process of how viruses hijack cells. Include the following words: membrane; protein
Kryger [21]

Answer:

The viral replication process begins when a virus infects its host by attaching to the host cell and penetrating the cell wall or membrane. Then the viral genome hijacks the host cell's machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids. In the past, viruses were considered nonliving infectious particles, little more than genetic material wrapped in a protein capsid. Today, virologists are beginning to think of viruses as living organisms that can be classified phylogenetically into defined species, much like any other living organism. The primary reasons for this shift in attitude can be partially attributed to the discovery of giant viruses, having large genomes and complex regulatory systems. Aside from that, it has become obvious that viruses lead complex lives; they evolve, speciate, and participate in the evolution of all classes of living organisms. In this chapter, we will discuss the early attempts to classify viruses, and review the biologic properties of the classes of virus that contain human pathogens.
