# Since the early 1990s, geneticists have produced ____________ crops that yield fruits and vegetables commonly found in U.S. supermarkets. A) large harvest B) genetically modified C) mutationally induced D) transgenically reduced

B) genetically modified.

Explanation:

Genetically modified foods are foods that are produced from organisms with DNA that has been modified through genetic engineering. This results in food that is more appetizing, more high-yielding or more resistant than food that has not been modified. This type of food is created in such a way in order for breeders to have better control over the positive traits of the organisms. These methods are similar to the more traditional selective breeding and mutation breeding.

Calculate the pI of Histidine (pKa’s = 2.3, 6.04, 9.33)6.11
7.68
3.08
2.35
4.07

Explanation:

Isoelectric point (pI) is the pH at which the amino acid has net a charge of zero. We have to choose the two values of pKa at which the neutral form of the amino acid is predominant. Histidine (Hys) is a basic amino acid. From pKa's data, we deduce:

pKa1 = 2.3 (corresponds to α- carboxyl group)

pKa2= 6.04 (corresponds to R group)

pKa3= 9.33 (corresponds to α- amino group)

Since it is a basic amino acid, the neutral form will exist between the higher pKa's values. Thus, the pI will be in a pH value between 6.3 and 9.33.

So, we have to calculate the average of pKa2 and pKa3:

pI= (pKa2+pKa3)/2= (6.04+9.33)/2= 7.68

Therefore, the pI of Hys is 7.68.

What group of organic molecules is made up of a sequence of an amion group, a carboxyl group, a hydrogen atom and a side chain bonded to the central carbon atom?AProteins
B Carbohydrates
C Nucleic acids
D Lipids

Proteins is made up of a sequence of an amion group, a carboxyl group, a hydrogen atom and a side chain bonded to the central carbon atom.

The group of organic molecules that consist of an amino group, a carboxyl group, a hydrogen atom, and a side chain bonded to a central carbon atom is known as proteins. The side chain, or R group, varies between different amino acids.

### Explanation:

The group of organic molecules made up of a sequence of an amino group, a carboxyl group, a hydrogen atom, and a side chain bonded to the central carbon atom is known as Proteins. Unlike nucleic acids, lipids, and carbohydrates, proteins are the only type of molecules that have this specific structure. This structure is known as an amino acid, and many of these amino acids link together to form proteins. The side chain, or R group, varies between different amino acids, and these variations provide the diversity in protein function and structure.
