Answer: D: They are closed at one end
Explanation:
"Lymphatic Capillaries" are tiny, thin walled microvessels located in spaces between cells and their main function is to drain and process extracellular fluid.
They are larger than blood capillaries and have "closed ends". Their unique structure permits interstitial fluid to flow into them but not out. Thus their ends are closed unlike the loop structure of blood capillaries.
<span>The first desirable trait that is being engineered into our crops is sustainability. This means that crops are being bred to be able to grow in adverse conditions, ensuring the ability to sustain our food supply as humans. The second, are the alterations being genetically done to crops to eliminate the need for pesticides. By heightening the crops natural ability to eliminate and deter pests, there are higher yields and the elimination of pesticides seeping into and poisoning the human consumer. And, finally an ability to eliminate the need for traditional breeding in crops. By genetically replicating plants, we are eliminating the chance that the human race may "run out", of seeds, of starts, of the need for pollination. This basically ensures us an unlimited food supply, just in these three traits being bred into our crops.</span>
