It acts as a framework inside the endoplasmic  reticulum  and keeps it from collapsing . it helps keep the organelles in place and directs their movement as needed . it keeps the DNA safely enclosed in the nucleus and holds the nucleus together . it provides anchoring places for the cell cytoplasm and help it move molecules .      maybe that help :)

Gradual change with a passage of time is called evolution
Explanation:
 
        
             
        
        
        
The answer is 1/2.
If:
R - t<span>he dominant allele for red kernels
r - t</span><span>he recessive allele for yellow kernels
Then:
RR - dominant homozygote
Rr - heterozygote
rr - recessive homozygote
The cross Rr x rr will result in 1/2 of offspring with red kernels (Rr) and 1/2 of offspring with yellow kernels (rr):
Parental generation:      Rr      x      rr
Offspring generation:  Rr    Rr     rr      rr
So, there are 2 out of 4 Rr offspring (2/4 = 1/2) and 2 out of 4 rr offspring (2/4 = 1/2).</span>
