Two methods of biotechnology used by scientists are described below.

Process A: Inserted a pesticide gene into a soybean
Process B: Used plants and microorganisms to create a new biofuel

Which process is likely to be more advantageous in conservation?

Process B because it will reduce our dependency on fossil fuels
Process A because it will increase the number of pests in the environment
Process B because it will cause an increase in fossil fuel pollution
Process A because more food will increase the global population

Question 8(Multiple Choice Worth 4 points)
(06.01 MC)

What is the likely advantage of growing a genetically modified variety of tomato that remains fresh over several days?

Post-harvest losses due to delayed transportation would be reduced.
Disease-causing pests may never be able to attack such a variety of tomato.
When consumed it would provide more nutrients than the regular variety.
When consumed it would improve the quality of life of people with genetic disorders.
Question 9(Multiple Choice Worth 4 points)
(06.01 HC)

A corn plant has been genetically engineered. It produces pollen that can make its own toxins. These toxins protect the corn plant against pests. What is a likely impact on the environment around the corn plant?

Bird and butterfly populations around the area may increase.
The concentration of pesticides in a nearby lake would increase.
Newer strains of pesticide-resistant pests may develop.
The carbon dioxide level would increase in the area.

Some steps in cell division are shown below:

1. Chromosomes condense and pair up
2. Segments of DNA of sister chromatids twist and cross
3. Exchange of DNA occurs between chromosomes
4. Four daughter cells are created that are haploid

Which of the following steps is least likely to occur during meiosis 1?

Step 1
Step 2
Step 3
Step 4
Question 11(Multiple Choice Worth 4 points)
(06.01 MC)

Which type of biotechnology would a dairy farmer use to mate the cows at his farm with genetically superior bulls to produce offspring that give high-quality milk?

Genetic engineering because the genes of the cows are altered
Genetic engineering because cows with desirable traits are produced
Artificial selection because offspring with desirable traits are produced
Artificial selection because the process reduces the production time of offspring
