Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pesticide contamination in fruit juices poses a potential health risk due to the toxicity of these chemicals. Excessive consumption of pesticide-contaminated fruit juices can lead to acute or chronic health effects, depending on the type and concentration of pesticides present.

Multiple choice

Which analytical technique is commonly used to detect pesticide contamination in fruit juices?

  1. Gas chromatography-mass spectrometry (GC-MS)

  2. High-performance liquid chromatography (HPLC)

  3. Spectrophotometry

  4. Immunoassay
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gas chromatography-mass spectrometry (GC-MS) is a widely used technique for detecting pesticide contamination in fruit juices. It involves separating and identifying individual pesticide compounds based on their mass-to-charge ratio, providing a comprehensive analysis of the pesticide profile.

Multiple choice

Which of the following is a natural pest control method used in organic farming?

  1. Using synthetic pesticides

  2. Releasing beneficial insects

  3. Applying chemical fertilizers

  4. Burning crop residues
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Releasing beneficial insects, such as ladybugs or lacewings, is a natural pest control method used in organic farming. These insects prey on pests, reducing their population and minimizing crop damage.

Multiple choice

Which of the following is a natural insecticide used in organic farming?

  1. Neem oil

  2. Synthetic pesticides

  3. Chemical fertilizers

  4. Burning crop residues
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Neem oil is a natural insecticide derived from the neem tree. It is effective against a wide range of pests, including aphids, mites, and whiteflies. Neem oil can be applied to plants as a spray or used as a soil drench.
