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:
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>
B) One swims freely and the other often lives attached to a hard surface.
