Answer:
Electrical gradient.
Explanation:
Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:
I) selective of ions pass through it.
II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.
IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels
Answer:
<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.
Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
Answer:
Hyponatremia is a condition in which the levels of sodium in the blood is too low. Some of the symptoms of hyponatremia include headaches, muscle cramps or spasm, seizures, weakness, restlessness, and confusion. Hyponatremia can occur from excess fluid in the body, or a loss of sodium in body fluid.
Explanation:
Answer: here´s why
Explanation: Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. If water is heated, its volume gradually decreases.
