<span>The correct
answer is B. Bees pollinating flowers.</span>
<span>
In biology, mutualism is how two different organisms survive upon the activity
of the other. Each benefits from the mutual relationship. In the case of bees
pollinating flowers, both the bees and the flowers need something and benefit
from the interaction with the other. </span>
 
        
                    
             
        
        
        
Answer:
Angiosperms
Explanation:
Angiosperms are important to humans in many ways, but the most significant role of angiosperms is as food. Wheat, rye, corn, and other grains are all harvested from flowering plants. 
 
        
             
        
        
        
Answer:
- Parental cross = Cch  x chch  
- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio
Punnett  square:  
           ch         ch
C       Cch       Cch
ch    chch      chch
  
Explanation:
A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

Answer:
Bacteria that are oxidase-negative may be anaerobic, aerobic, or facultative; the oxidase negative result just means that these organisms do not have the cytochrome c oxidase that oxidizes the test reagent. They may respire using other oxidases in electron transport.)
