Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
Answer:
A) potential energy called chemical energy.
Answer:
RNA polymerase creates mRNA when it is is in the starter called Positive transcription factor 5. What does the “mRNA destroyer” do? It destroys the mRNA when there is enough mRna 6. ... Negative transcription doesn't allow mRNA to produce more 7.
Explanation:
Answer:
Number of nucleosomes in 
bp is equal to 
Explanation:
For wounding one nucleosome, total length of DNA required is equal to 
bp
The length of linker DNA in mammals is equal to 
bp
Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length
bp
Thus, in 
bp length of DNA, the total number of nucleosomes is equal to 
Thus, number of nucleosomes in bp is equal to
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
