Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses.
The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine.
Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.
Fishing until reaching an established quota that allows the fish population to rebound each season is a method of sustainable fishing
<h3>What is sustainability ?</h3>
The main objective of sustainability is for people to live in peace and harmony on Earth for an extended period of time. Specific definitions of sustainability are difficult to agree on and hence vary in the literature and across time
- Sustainability is often represented diagrammatically. The figure at the top of this page suggests that there are three pillars of sustainability – economic viability, environmental protection and social equity.
- Sustainability is important for many reasons including: Environmental Quality – In order to have healthy communities, we need clean air, natural resources, and a nontoxic environment. Growth - UNTHSC's enrollment continues to expand, thus we demand additional resources such as energy, water, and space.

Plasma membrane,DNA,ribosomes,and ctyoplasm
The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container.
Explanation:
Answer:
Inside the axon terminal of a sending cell are many synaptic vesicles. These are membrane-bound spheres filled with neurotransmitter molecules. There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.
