Answer 6

International Rice Research Institute, Los Banos, Laguna

Question 7

Any of a group of genetically enhanced cultivars of crops

Answer 7

High-yielding Varieties

Question 8

First component of technology was the development of HYV’s

Answer 8

High Yielding Hybrid

Question 9

Varieties were developed that were?

Answer 9

Shorter with stronger stem and roots

Question 10

Give effects of pesticide to the environment. Air pollution

Answer 10

• pesticide drift occurs when pesticides in the air are carried by wind to other areas
• can volatilize, posing a threat to wildlife
• droplets of sprayed pesticides may travel on wind

Question 11

Produces less pesticide drift than aerial spraying does

Answer 11

Ground spraying

Question 12

Give effects of pesticide to the environment. Water pollution

Answer 12

• may drift outside its intended area when sprayed
• may percolate
• may carried to water as runoff
• may be spilled

Question 13

Give effects of pesticide to the environment. Soil pollution

Answer 13

-decreases the general biodiversity in the soil

Question 14

Give effects of pesticide to the environment. Plants pollution

Answer 14

-pesticides hinder nitrogen fixation, which is required for the growth of the plants

Question 15

The planting of vast areas to only one crop

Answer 15

Monocropping/ Monoculture

Question 16

Produces genetically modified organisms (GMO)

Answer 16

Genetic Engineering

Question 17

Also called transgenic maize corn and is a genetically modified crop

Answer 17

Bt Corn

Question 18

What does BT from BT corn means

Answer 18

Bacillus Thuringiensis

Question 19

Micro organisms found in soil that protects the corn from insects

Answer 19

Bacillus Thuringiensis

Question 20

What is the pest that usually affects corn production

Answer 20

European corn borer

Question 21

A population of what kind of butterfly was affected when pollen of Bt corn was carried by wind

Answer 21

Monarch Butterfly

Question 22

Utilizes species that are locally available and are therefore suited to environmental conditions

Answer 22

Organic farming

Question 23

How does organic farming optimizes the use of biological processes

Answer 23

1. By nurturing the natural predators of pests
2. Keeping the soil healthy with beneficial microorganisms
3. Allowing wild species from nearby natural ecosystems to pollinate crops
4. Encourages variety in space and variety in time through crop rotation
