The human brain communicates with the rest of the body through networks of what?

Biology
2 answers:
True [87]2 years ago
8 0

Through nerves attached to the brain and to the spinal cord. When an action potential traveling down the axon reaches a terminal button, they secrete a chemical called a neurotransmitter.

The brain communicates with the rest of the body through the spinal cord, which runs from the base of the brain all the way down the back. The spinal cord is made up of lots of nerves, and these nerves branch out into more nerves that travel to every part of the body.

Answer:

in group 5. Organic Wastes

Explanation:

Remember in a chemical lab, in a hospital or in an industry there is always some wastes that need to be treated in an specific  way. There are 19 categories in which the wastes need to be poured in order to be treated. The starch is an organic waste that normally is involve in biological processes. This waste is consider as a non - toxic, in this way can be join with other organic wastes as acetic acid, peroxide, etc.

Why does the actions of the thymus demonstrate a close functional connection between the lymphatic system and the endocrine syst
OleMash [197]

Answer:

The Thymus is a unique gland which protects the body against autoimmunity when the immune system act against itself.Hence the Thymus plays a significant role the dual systems i.e.,the lymphatic system (body’s defensive mechanism) and the endocrine system

Explanation:

The Thymus is special gland located anteriorly to the chest directly behind the sternum and in between the lungs. Active until puberty and gradually shrinks to become fat after puberty.

Function: Prior to birth and during childhood thymus engage in producing and maturation of T-lymphocytes or T-cells a particular type of white blood cells which defence the body against infectious disease germs.Though the organ does not function throughout the life span but it plays a significant role protecting the body against autoimmunity refers to an immune system works against itself .Therefore the thymus plays a key role in lymphatic system and an endocrine system.

Secretion:Thymus secretes Thymosin a hormone it instigates the development of T-Cells ( disease resisting cells) Thymosin stimulates the development of T-Cells until a human attains its puberty. At the age of 75 thymus becomes a fatty tissue.

Sodium ions, oxygen (O2), and glucose pass directly through lipid bilayers at dramatically different rates. Which of the followi
Elodia [21]

Answer:

The correct order, from fastest to slowest, for the passage of molecules and ions through the cell membrane is oxygen, sodium ions, glucose (option D).

Explanation:

The plasma membrane is a lipid bilayer, with glycoproteins and membrane proteins, which constitutes a semi-permeable barrier to the passage of substances into and out of the cell.

The speed with which a substance can pass through the membrane depends on its chemical properties -hydrophilic substances pass through with greater difficulty than lipophilic ones- requiring in some cases specialized transport mechanisms. The different rates with which a substance passes depends on this.

  • <em>Oxygen (O₂) </em><em>passes through simple diffusion, depending on a concentration gradient. It's the molecule that passes through the membrane the fastest. </em>
  • <em>In second place, there would be the </em><em>Na⁺ ions</em><em> -charged atoms- that cross the membrane by facilitated diffusion, through specific ionic channels. </em>
  • <em>The </em><em>glucose</em><em> molecule, being larger, requires the use of transport proteins, being its passage through the membrane slower with respect to oxygen or sodium.</em>

Undoubtedly, molecular weight and affinity for the plasma membrane are determining factors for the passage of molecules through the lipid bilayer.
