A gene for disease resistance in fir trees is transferred to pine trees using modern DNA technology. How might this be economically helpful to tree farmers?
A) Abnormal pine tree growth would be eliminated.
B) Erosion of topsoil would no longer be a concern.
C) Pine trees would be safe from pine beetle attacks.
D) More pine trees would live to maturity, increasing lumber output.
I think A or D.
The correct answer is D) More pine trees would live to maturity, increasing lumber output. By transferring a gene for disease resistance from fir trees to pine trees, the resulting genetically modified pine trees would have an increased ability to resist diseases that could otherwise kill them. This would result in more trees reaching maturity and therefore increasing the lumber output for tree farmers.
To determine which option, A or D, is more economically helpful to tree farmers, we need to assess the potential economic benefits of each.
Option A: Abnormal pine tree growth would be eliminated.
If the gene for disease resistance in fir trees is successfully transferred to pine trees, it could potentially eliminate abnormal pine tree growth caused by diseases. This could lead to healthier and stronger pine trees, reducing the impact of diseases on the trees' growth and overall productivity. However, this benefit may not directly translate into significant economic gains for tree farmers unless abnormal tree growth has been a significant problem, affecting the quality or marketability of the trees.
Option D: More pine trees would live to maturity, increasing lumber output.
On the other hand, if the transfer of disease resistance genes from fir trees to pine trees leads to a higher number of trees surviving to maturity, it could significantly increase the overall lumber output for tree farmers. This would result in a larger supply of pine wood available for harvesting and potentially higher revenues for the farmers.
Considering the potential economic impact, option D seems to be more beneficial for tree farmers. Increasing the number of pine trees that reach maturity and can be harvested for lumber directly contributes to increased productivity and potential profitability for tree farmers.
Therefore, the correct answer is option D: More pine trees would live to maturity, increasing lumber output.
Correct! Both options A and D would be economically helpful to tree farmers.
A) Abnormal pine tree growth would be eliminated: By transferring the disease-resistant gene from fir trees to pine trees, any abnormal or stunted growth caused by diseases would be eliminated. Healthy and robust pine trees would be more desirable for lumber production, resulting in higher quality wood and increased profits for tree farmers.
D) More pine trees would live to maturity, increasing lumber output: Disease-resistant pine trees would have a higher survival rate, reducing losses due to disease outbreaks. This would result in more pine trees reaching maturity and being ready for harvesting. Increased lumber output means more products to sell and higher potential revenue for tree farmers.
Both options A and D showcase the economic benefits of transferring the disease resistance gene to pine trees, making them valuable considerations for tree farmers.
