Answer:
Oxygen
Explanation:
The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.
Answer:
Exocytosis.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles
Exocytosis can be defined as a process which typically involves a cell releasing a large amount of a material (bulk transport) outside of the cell, using vesicles.
This ultimately implies that, exocytosis is a process in which living organisms release or expel large amount of unwanted material through the use of vesicles. Vesicles are cell organelles that ensure materials are properly transported to the right and exact location.
Additionally, exocytosis is a process initiated by the Golgi apparatus because it prepares the material for export by chemically tagging them.
The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
<h3>
How do materials move within the earth?</h3>
The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.
So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
