cultivation. and to try to make suggestions so we can say look you ve identified a characteristic that helps make the plants drives resistant and for example it s roots my grow very fast or very slowly that s a factor that should be taken into account by researchers aiming to adopt plants to climate change flexible hide and photosynthesis rates are a good indicator of a plant s overall health the imaging system detects fluorescents a method from chlorophyll if the leaf appears bread on the screen it means the rate of photosynthesis is poor and the plant is struggling to grow. some honey off by plants close their stuff to limit water of operation from their leaves marsh. and that s if we observe as an early stage mother plant is closing its tomatoes so we can do something about it. we could water it for example that he s norman is also a member of the research team he hopes that one day he ll be able to measure
needs help and she s getting it from a feds that she finds on the plane and there s none there. none there either. but then she finds one it s not hard to catch and eat it. i just need a small container underbrush. and then i very gently brush the a fit into the container. so i just throw the main one by one. the a fed grows a little agitated and with good reason low house gives it a new leaf to feed on and then places the whole thing under the microscope the composition of flow and sap changes depending on the location and the leaf to find out more the biologist wants to capture a live image of what s happening in the leaf cells but she 1st needs to know which of them currently contain sugar crushing the leaves to find out isn t an option.
transmitted to other parts of the plant when it s attacked or damaged. signals and plants can also be electrical. when a particular stimulus reaches a certain threshold they can trigger what s known as an action potential and bang there s a reaction. to suffer. mentally it s comparable to what happens in human cells if there are certain types of electrical signals that so far have only been found in plants flunking fun and rewarding. scientists call these other signals system potentials they ve observed how an impulse triggers changes and the voltage at the so membrane in simple terms the positive charge outside the cell increases but instead of the membrane reacting with a sudden discharge when stimulated as happens with an action potential the increased voltage is passed on systemically from cell to cell from the leaf to leaf.
used to be way to europe many commonwealth leaders did not want the u.k. to leaf. now their support will come at a price i took a very good record of their support may come at a price what price could britain have to pay here. well first of all to be a more equal footing that which also many of the delicate have just eluded to and virtually all the people have spoken out in this commonwealth meeting have have alluded to the same thing that they want a more level playing field more equal relationship and nobody really wants to go back to anything that smells of the old and then again there are also some really concrete demands break sample india which of course is a very attractive economy to the frayed trade deal with the free trade deal with but they did more and a lot of good will from britain when it comes to visa for example we have indian
later this afternoon leon panetta due to leaf his post in mid-february will announce that the pentagon is removing their ban on women serving in combat roles. the decision could open 230,000 jobs to women who will now be able to serve on the frontlines. lee, this seems like a no-brainer, and, yet, the wall street journal has this to say about it. owe despite the professionalism of marines, it would be distract and potentially traumatizing to be forced to be naked in front of the opposite sex, particularly when your body has been ravaged by lack of hygiene. in the reverse it would be painful to witness a member of the opposite sex in such an uncomfortable and awkward position. ravaged by that s exactly right. body odor that costs the army its victories. what? i didn t know hygiene or its lack could ravage you. as you pointed out, how many times were people fighting in
