The correct Answer is:
To determine the correct statements from the given options, let's analyze each statement step by step: ### Step 1: Analyze Statement A **Statement A:** Wheat variety, Atlas 66 having a high protein content. - **Evaluation:** This statement is true. Atlas 66 is known for its high protein content and has been used in breeding programs to improve the protein quality of wheat. **Hint for Step 1:** Look for specific characteristics of the mentioned wheat variety to confirm its protein content. ### Step 2: Analyze Statement B **Statement B:** SCP is the alternate source of proteins for animal and human nutrition. - **Evaluation:** This statement is true. SCP stands for Single Cell Protein, which refers to protein extracted from single-celled organisms. It is indeed used as an alternative protein source for both animals and humans. **Hint for Step 2:** Consider the definition of SCP and its applications in nutrition. ### Step 3: Analyze Statement C **Statement C:** Plants developed by micropropagation will be genetically different from the original plants from which they were grown. - **Evaluation:** This statement is false. Micropropagation is a technique that produces clones of the original plant, meaning the new plants are genetically identical to the parent plant. **Hint for Step 3:** Recall the principles of micropropagation and how it affects genetic similarity. ### Step 4: Analyze Statement D **Statement D:** Semi-dwarf rice varieties were derived from IR-8 and Taichung Native-1. - **Evaluation:** This statement is true. Semi-dwarf rice varieties, which contributed to the Green Revolution, were indeed developed from IR-8 and Taichung Native-1. **Hint for Step 4:** Research the origins of semi-dwarf rice varieties and their impact on agriculture. ### Conclusion After evaluating all the statements: - **Correct Statements:** A, B, and D are true. - **Incorrect Statement:** C is false. ### Final Answer The correct statements are A, B, and D.

In the first biological applicativon of bucky ball , chemists at the University of Califorminaat San F Francisoc and Santa Barbra made a discovery in 1993 that could help I designing drugs to rtreat AIDS . The human immunodeficienrcy virus (HIV) that causes AIES reproduces by syntheising a long protein chain , which is cut into smaller segments by an enzymecalled HiV-proteases . ONe way to stop AIDS , then might be to inacivate the enzyme. when the chemists reacted a water-soluble derivative of bucky ball with HIV-protease , they found that itbinds to the portion of th enzyme that would ordinarily clareve the repreouctive protein , preventing the HIV virus from reproducing . Consequently the virus could no bnolgre infect the human cells they had frown in the laboratory . The buycky ball compound itself is not a suitable drug for use against AIDS because of potential side effects and delivery difficaultes , but it does provide a model for the development of such drugs Consider following statements about bucky ball : A , It is also called fullerene B: It is also called Buckminster fullerene C: Bucky tubes (made of fullerenes ) are several times stronger than steel wires D: Bucky ball is a plastic polymer Select correct statement (s) :
