Explanation:
<span>The information that
determines what the organism will be like is the DNA molecule. It is made up of
nucleotides. These nucleotides are linked chains. The four types of bases found in nucleotides are: adenine,
thymine, guanine, cytosine. The order of the bases determines what instructions are contained on the strand. For example, say a strand shows
ATCTT and say that presents in a person who has blue eyes while other eye
colors would be a different code. Wach piece of code determines what the organism will be like based on those pairs.</span>
The answer is D. Species A will have fewer phenotypes.
Alleles are alternative forms of a gene. In species A, the leaf color is controlled by two alleles, for example, P and Q. They will have three possible genotypes - PP, PQ, and QQ. Three different genotypes give maximum three phenotypes.In species B, leaf color is controlled by three alleles, for example, L, M, and N. They will have six different genotypes - LL, LM, LN, MM, MN, and NN. Six different genotypes give maximum 6 phenotypes.
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
• Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
• Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
Explanation:
The autonomic nervous system controls internal body processes such as the following:
Blood pressure
Heart and breathing rates
Body temperature
Digestion
Metabolism (thus affecting body weight)
The balance of water and electrolytes (such as sodium and calcium)
The production of body fluids (saliva, sweat, and tears)
Urination
Defecation
Sexual response
