Answer: Ligament
Explanation:
Ligaments are tissues which possess enough strength to attach bones to other bones.
Tendons on the other hand attaches muscles to bones, while cartilages are connective tissues that often play the role of bone before being replaced as an organism develops.
The synovial fluid lubricates the cartilage found at synovial joints during movement preventing shock or friction.
So, the correct answer is Ligament
Answer:
Higher food production per unit of agricultural land
Explanation:
With respect to the rate of fertilizer usage in relation to food production over the past 40 years, we can assume that we are almost getting to the limit to which Nitrogen fertilizer input can further increase food production using the same area of land. Further higher input of nitrogen fertilizer might be counter productive, and neither do lower use of Nitrogen fertilizer per unit area solve the predicted increase in demand of food in the future. The most plausible statement that represents future agricultural changes for maintaining an adequate food supply in response to growing population is “Higher food production per unit of agricultural land”. This can be achieved through other technological innovations compared to nitrogen use.
