The targets were in Africa, which is not far from the Middle East is the correct answer.
The Al-Qaida-the Islamic Militant organisation who were responsible for 9/11 attack, likely choose its first American bombing targets in Africa, which is not far from middle east, the latter being the cradle of al-Qaida.
Biology, chemistry, and geology is the answer.
b. They have been genetically modified.
c. They were developed during the Green Revolution.
d. Genetic material from another organisms is sometimes added
The bioengineered food products are those food products, which are modified by the alteration in their genetic material. There alteration in the genetic material is done by changing and incorporating the gene of interest in the DNA of the organism. Sometimes, the gene of interest are derived from the genome of the other organisms.
The use of the chemical pesticides escalated the green revolution, at that time the genetically modified food product were not so developed.
Hence, the correct answer is c. They were developed during the Green Revolution.
B. Vascular tissue
C. Dermal tissue
D. Apical meristem
Answer:
Explanation: Cytological markers such as the translocated segment and the chromosome knob play a crucial role in various biological research and applied sciences. These markers have proven to be invaluable tools for understanding genetic diversity, evolution, and gene mapping in organisms. The translocated segment, which is an exchange of genetic material between nonhomologous chromosomes, can provide insights into evolutionary relationships between species. By studying translocations, scientists can determine how different species are related and how genetic material has been exchanged or rearranged during evolution. On the other hand, the chromosome knob is a distinguishing structure found on certain chromosomes that serves as a reliable cytological marker for gene mapping and breeding programs. It facilitates the identification of specific genes associated with particular traits or diseases through cytogenetic techniques. Moreover, these cytological markers enable researchers to develop breeding strategies that aim at improving crops' yield, disease resistance, or other desirable qualities by precisely transferring particular chromosomal segments or genes identified by the presence of knobs and translocations. Hence, understanding the significance of cytological markers is vital for both basic scientific discoveries and practical applications in agriculture and medicine.
