which would result in higher food production at a lower cost? select four options.\n□ cows that are able to fight off diseases\n□ rice that has added provitamin a\n□ corn that is resistant to diseases\n□ wheat that is not killed by weed killer\n□ corn that can grow in cold places
Answer
Brief Explanations:
- Disease-resistant cows: Reduces loss from illness, boosting production without extra cost.
- Disease-resistant corn: Lowers crop loss and need for expensive treatments, raising output at lower cost.
- Weed-killer tolerant wheat: Lets farmers use herbicides to eliminate weeds (which reduce yield) without harming wheat, increasing production efficiently.
- Cold-tolerant corn: Expands growing areas, increasing total production without raising per-unit costs. Rice with added provitamin A improves nutrition but does not directly boost production or lower costs.
Answer:
- cows that are able to fight off diseases
- corn that is resistant to diseases
- wheat that is not killed by weed killer
- corn that can grow in cold places
