which if the follwing is a disadvantage of the overuse of artificial fertilizers

Answers

Answer 1

The correct option is B. Excess nitrogen causes algal blooms. Overuse of artificial fertilizers, specifically nitrogen-based fertilizers, can lead to an increase in nitrogen runoff into nearby water bodies such as rivers, lakes, and oceans.

This excess nitrogen can act as a nutrient for algae, promoting their rapid growth and reproduction. As a result, algal blooms can occur, leading to the depletion of oxygen in the water and negatively impacting aquatic ecosystems. The reduced oxygen levels can harm fish and other organisms, causing them to die.

As mentioned in option A and D, it's not typically associated with the overuse of artificial fertilizers but excess of carbon dioxide (CO2) emissions can contribute to climate change but are not directly related to the use of fertilizers.

Option C, excess nitrogen causing plants to die, is not accurate. While high levels of nitrogen can have negative effects on plants, such as inhibiting root development, burning foliage, or disrupting nutrient balance, it does not generally cause plants to die.

Which property of a plant species would be MOST USEFUL for meeting the scientists' goal?

Answers

The property of a plant species that would be MOST USEFUL for the scientists' goal of developing a useful crop plant through selective breeding is Very high genetic variation. The correct answer is option B.

High genetic variation within a plant species means that there is a wide range of genetic traits and characteristics present. This provides a greater chance of finding desirable traits that can be selected for and developed in the breeding process. By selecting plants with specific desired traits and crossing them, scientists can increase the likelihood of producing offspring with those traits. Over time, this can lead to the development of a new plant variety with improved qualities such as higher yield, resistance to pests or diseases, or improved nutritional value. Therefore, the correct answer is option B.In summary, a plant species with very high genetic variation would be most useful for the scientists' goal of developing new farm crops through selective breeding because it increases the chances of finding desirable traits and allows for the development of improved qualities in the offspring.
