Genetic Engineering  

Benefits  

-Ability to create food that is resistant to pests, cold, and disease.  

-Greater food production volume and increased vitamins.  

Risks  

-Concerns about long-term health risks.  

-Lack of regulation.  

Cloning  

Benefits  

-Ability to increase endangered animal populations.  

-Possibility of eliminating diseases and defective genes.  

Risks  

-Shorter lifespan for cloned animals.  

-Greater chance of health issues for cloned animals.  

Artificial Selection  

Benefits  

-Allows for selection of desired traits.  

-Ability to create better versions of organisms.  

Risks

-Loss of genetic diversity.  

-Increased chance of diseases that can shorten lifespan.

Explanation:

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
