Answer:
<u>Cilia</u>
Explanation:
Cilia and flagellum are made up of microtubules. 
Cytoskeletal filaments are structures which allow movement. In cilia and flagella, the cytoskeletal filaments are present in the form of microtubules and the primary work of these structures is to facilitate in movement. 
Cilia is also present in mammals to facilitate the movement of fluids in cells. 
Structurally, there is no difference between cilia and flagella. The only difference between cilia and flagella is in their lengths.
 
        
             
        
        
        
Answer:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the  nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus. 
 
        
                    
             
        
        
        
Answer:
The tree will not survive due to the nature of the tundra
Explanation:
The tundra comes from a finnish word "tunturia" which means barren or treeless land. It is classified as a cold icy desert with permafrost on the ground. Unlike the tropical rain forest which is a wet climate group and is a forest of tall trees in a region of year round warmth, the tundra is cold and dry. The tundra soils are formed at high altitudes, they are usually frozen. Common plants in tundra are shrubs, herbs, lichens and grass and usually grow in groups and remain closer to the ground for prevention against cold winds. The cold nature of the tundra and its soil prevent the growth of trees because trees need to have deeper roots and they cannot grow on frozen ground.
