Answer:
Cool dense water sinks to the ocean floor.
Warm water replaces cool surface water.
Wind blowing parallel to the shore causes upwelling of cool water.
 
        
             
        
        
        
When food is digested, the food is broken down into Glucose, which can get into the bloodstream through the small intestines. It travels around the body in the bloods plasma and is then diffused into the body's cells through the capillaries. Once the Glucose is in the body cells, it can be used for respiration.
The breathing system is used in respiration because we need it to respire aerobically, so that our body gets all the vital oxygen it needs. When we breathe, oxygen is stored in the alveoli in the lungs. From there, it can be diffused into the bloodstream, to be used for respiration.
The products of aerobic respiration is Carbon Dioxide and Water. The Water leaves the body as sweat or waste such as urine. The Carbon Dioxide is carried through the blood to our lungs where we can breathe it out. Where as in anaerobic respiration, the product is Lactic Acid. This ends up being broken by oxygen after exercise (oxygen debt) and is also turned into Carbon Dioxide and Water.  
        
             
        
        
        
During the metaphase, chromosomes are taken to the equatorial plane, were they randomly line up. Option B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
 
<h3>What is the metaphase?</h3>
 
Metaphase is one of the cell division stages that follows the prophase and precedes the anaphase.
 
During this phase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes randomly line up.
 
Once aligned, each chromatid joins with a microtubule of opposites poles and gets ready to go through the anaphase. Sister chromatids are held together until they reach the Anaphase.
Since chromosomes in this stage are well defined and can be observed in detail under the microscope, they are used to create karyotypes and identify chromosomal abnormalities. 
These chromosomes have the typical X shape. 
Among the options, the one that correctly describes the metaphase is Option is B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
