Question

at one time, farmers had to spray insecticides on their fields to protect their crops from insects. today, farmers can buy seeds that produce plants that are resistant to many insects. which process contributed to the development of these seeds? a cloning b artificial selection c genetic engineering d asexual reproduction the two mice pictured below are genetically identical how were they produced?

Explanation:

• Question 3:
• Cloning is creating an identical copy of an organism. But the seeds here are about introducing new traits (insect - resistance) rather than just copying.
• Artificial selection is choosing organisms with desired traits for breeding. While it can lead to some trait improvements, genetic engineering is more precise for introducing specific genes (like those for insect - resistance).
• Genetic engineering involves directly manipulating an organism's genes. This is how seeds can be made to produce insect - resistant plants.
• Asexual reproduction is a mode of reproduction (like budding, fragmentation) and not a process for developing such seeds.
• Question 4:
• If two mice are genetically identical, they are likely produced by cloning. Cloning techniques (such as somatic cell nuclear transfer) can create organisms with the same genetic material.

Answer:

• Question 3: C. Genetic Engineering
• Question 4: By cloning.
