The recent manuscript "Biomechanics: Cell Research and Applications for the Next Decade" Ann Biomed Eng. 2009 May;37(5):847-59, by Discher, Dong, Fredberg, Guilak, Ingber, Janmey, Kamm, Schmid-Schönbein and Weinbaum discusses the challenges for cell mechanics now and in the future. 4.1 Read the manuscript carefully and summarize it with approximately 150 words (do not copy abstract). 4.2 The authors have identified ten major accomplishments in cell mechanics. List all the ten accomplishments by title. 4.3 Select your favorite past accomplishment and describe it in less than 100 words. 4.4 The authors have identified seven major challenges for the future. List all the seven future challenges by title. 4.5 Select your favorite future challenge and describe it in less than 100 words.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
