Answer:
Limits platelets population.
Explanation:
The result of this  modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body. 
 
        
             
        
        
        
1. fossils and chemical isotopes found in sediments and glacial ice
By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.
2. decrease in mortality because winter is warmer
The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm. 
Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.
 
3. all activities by humans affecting the Earth and its biosphere
Anthropogenic activities are all activities by humans affecting the Earth and its biosphere.
4. decline in sea ice
The main cause behind declining numbers of polar bears is the diminishing size of the sea ice. The bears use the ice as hunting ground where they stalk seals. 
 
        
             
        
        
        
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.
 
        
             
        
        
        
Answer:
 The part of the cell that is in charge of the synthesis of proteins are called Ribosomes.
