Answer:
Cells --> Tissues ---> Organs --> systems
Explanation:
There are four levels of organization of life in organisms. These are the cells, tissues, organs and systems.
- Cells
This is the first and simplest level of organization of life. Cell is the smallest unit of body of living organisms. Examples of cells are rod and cone cells in the eyes, nerve cells, red blood cells etc
- Tissues
A tissue is the second level of organization of life. It is a group of similar cells forming a layer in an organism which performs a particular function. Examples of tissues include blood and muscles
- Organs
An organ is the third level of organization of life. It is a group of similar tissues forming a layer which performs a specific function. Examples of organs in the body include skin and eyes
- System
An system is the fourth level of organization of life. It is a group of similar organs which work together to perform specific functions. Examples of systems in the body of animals include nervous and digestive system. The systems then work together to make up the body of an organism.
Thus, the correct order from the most simplest to the most complex is:
Cells --> Tissues ---> Organs --> systems
Answer:
spiders
Explanation:
While humans and many other species have red blood, due to the iron in their hemoglobin, other animals have different colored blood. Spiders(as well as horseshoe crabs and certain other arthropods) have blue blood due to the presence of copper-based hemocyanin in their blood. Some animals, such as the sea cucumbers, even have yellow blood.
Magnetic energy builds up in the sun.
- When the energy is released, this is called a solar flare.
Answer:Hemopure is a blood substitute developed by Biopure Corporation. *consists of hemoglobin, purified from bovine blood, free in the plasma. *binds oxygen in the lungs then delivers oxygen to the body. *cell-free hemoglobin releases the oxygen more quickly than red blood cells. *risk of high blood pressure and heart attacks.
