Gluten is a mix of proteins that are produced in some grains, such as wheat. Rice does not naturally contain gluten in its grains. However, scientists have used a method which induced mutations in rice plants and successfully created a strain of rice that produces gluten. The method involved exposing plants, seeds, or pollen to radiation. The resulting plants were then grown and tested for different traits.

Due to mutation.

Explanation:

Due to mutation, the rice plants are able to produce gluten like other grain crops such as wheat etc. In this mutation, change occurs in a DNA sequence of the rice plant by exposing the plant to ionized radiation. Due to this radiation, change occurs in the DNA of rice plant and the rice plant is able to produce gluten like wheat plant. So mutation is a very useful method for producing substances which a plant can't produce in its normal condition.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
