The correct answer is option A, that is, FFA (Future Farmers Association).
The FFA creates a positive distinction in the lives of students by creating their tendency in premier leadership, career success, and personal growth via agriculture education.
It is the premier youth organization, which prepares members for careers and leadership in the business, science, and technology of agriculture. The population of the planet will be around 9.8 billion by 2050, thus, needing a 60 percent enhancement in the production of agriculture. Therefore, a rapidly developing talent, technical aptitude, and innovation are needed to meet this challenge.
The right answer is Scientists should conduct long-term studies of DNA technology to determine the consequences.
DDT is a potent insecticide: it kills by opening the sodium channels of insect neurons, destroying them instantly, leading to spasms and then death. Some genetic mutations acting on the sodium channels can make some insects resistant to DDT and other insecticides working on the same principle.
The US Environmental Protection Agency has categorized DDT into the B2 class, that is, potential carcinogen for humans. This supports the fact that the insecticide acts on human DNA.
B) legally and appropriately transferred care
Answer:
The cause of respiratory distress syndrome in premature infants is <u>lack of surfactant in the lungs because the lungs has not fully developed.</u>
Explanation:
Respiratory distress syndrome is a type of neonatal disease of respiration caused by the lack of surfactant production by the lungs.
Normally the lungs of fetus start the formation of surfactant during the third trimester of pregnancy (26 weeks through labour and delivery ). The surfactant is produced by type II alveolar cells and is the lipoprotien complex that has surface tension lowering effect (surface active agent ) having both hydrophobic and hydrophilic properties thus coats the air sacs and alveoli.
In the premature infants, the lungs are not fully developed hence the adequate amount of surfactant is missing thus resulting in Respiratory distress syndrome.
