Research in plant biotechnology has focused primarily on characteristics that
a. improve resistance to pests, reduce the need for pesticides, and increase survival rates in adverse growing conditions.
b. allow genetically engineered seeds to be prepared within two months.
c. allow genetically engineered seeds to double in size within one year.
d. reduce the need for other genes to be introduced into a plant genome.

a. improve resistance to pests, reduce the need for pesticides, and increase survival rates in adverse growing conditions.

Plant biotechnology is a sub field of biotechnology which studies about the diversity of plant species and manipulates the genome of the plants in such a manner so as to make them resistant against the pests and diseases hence pesticides are not required, improving the yield of the crops, making the crops resistant against the adverse environment conditions like drought and thunderstorm.

On the basis of the above description, a. improve resistance to pests, reduce the need for pesticides, and increase survival rates in adverse growing conditions is the correct option.

where is the option.let me know

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
