Mirroring the way many universities split their content, this specification gives students a broad range of experience in the three areas of physical, organic and inorganic chemistry. These guides were updated in February to reflect the latest specification changes. Prepare for your year ahead by accessing the essential information you need to deliver the International A-level Chemistry specification. They are related to, but separate from, knowledge of the subject content. The Scheme of Work provides a suggested pathway through the specification, enabling you to plan your course.

Attraction of water molecules to the Walls adhesion from the stem water enters the xylem of leaves water moves in the xylem vessels of the stem in a continuous uninterrupted water column up to the tree leaves Leaves once in the leaves water moves into the mesophyll cells by osmosis as water vaporizes from the spongy mesophyll cells their sap becomes more concentrated than the adjacent cells as the result water flows into the cell from other surrounding cells which in turn takes in water from xylem vessels within the leaf veins this creates a pull suction force called transpiration pull that pulls a stream of water from xylem vessels in the stem and roots. The transpiration pull maintains a continuous column of water from the roots to the leaves. Absence of cuticle also increase rate of transpiration ii Explain the environmental factors that affect rate of transpiration in plants high temperature increases rate of transpiration and low temperature reduces the rate humidity when high increases rate and when low reduces the rate transpiration rate is higher in moving air wind than in still air high light intensity increases internal temperature hence higher rate of evaporation leading to higher rate of transpiration availability of water in the soil leads to more absorption hence more loss to the atmosphere atmospheric pressure when high leads to more evaporation and when low leads to low rate evaporation of water iii State the structural differences between xylem vessels and sieve tubes sieve tubes have cross wall while xylem vessels have none xylem vessels are lignified while sieve tubes are not Sieve tubes have cytoplasm elements while xylem vessels have none. Water vapour accumulates in the depression of stomata lowering the water vapour concentration gradient leading to lower rate of evaporation rolling of leaves v State the factors that cause increase in the rate of transpiration from leaves increased light intensity low relative humidity temperature vi Explain how drooping of leaves on a hot sunny day is advantageous to a plant reduces surface area exposed to sun reducing cuticular transpiration c Explain how aquatic and terrestrial plants are adapted to deal with problems of transpiration a. Mesophytes they grow in soils with enough water water loss is perfectly balanced by absorption of more from the soil no special adaptations b. Either cut a stem of a young plant or twig of a tree under water or else uproot a young herbaceous plant and wash the soil gently put some water in a beaker and add a dye i. OR use radio-active tracers, C14 in form of carbon ring a plant then put it in a container containing radio-active phosphorous solution The radio-active phosphorus is later detected in the leaves.

ГЛАВА 39 Росио Ева Гранада стояла перед зеркалом в ванной номера 301, скинув с себя одежду. Наступил момент, которого она с ужасом ждала весь этот день. Немец лежит в постели и ждет. Самый крупный мужчина из всех, с кем ей приходилось иметь. Нарочито медленно она взяла из ведерка кубик льда и начала тереть им соски. Они сразу же затвердели. Это было одной из ее многочисленных хитростей: мужчинам казалось, что она сгорает от страсти, поэтому они стремились прийти к ней снова и .

Неисправность ТРАНСТЕКСТА угрожала и базе данных, а легкомыслие Стратмора не имело оправданий. Всем известно, что ТРАНСТЕКСТ и главная база данных АНБ тесно связаны между. Каждый новый шифр после его вскрытия переводится на безопасное хранение из шифровалки в главную базу данных АНБ по оптико-волоконному кабелю длиной 450 ярдов. В это святилище существует очень мало входов, и ТРАНСТЕКСТ - один из. Система Сквозь строй должна служить его верным часовым, а Стратмору вздумалось ее обойти. Чатрукьян слышал гулкие удары своего сердца. ТРАНСТЕКСТ заклинило на восемнадцать часовМысль о компьютерном вирусе, проникшем в ТРАНСТЕКСТ и теперь свободно разгуливающем по подвалам АНБ, была непереносима.

Скорее бы просигналил ее терминал. Но тот молчал. Конец лета. Солнце уже зашло. Над головой автоматически зажглись лампы дневного света.

И вот Халохот уже за спиной жертвы. Как танцор, повторяющий отточенные движения, он взял чуть вправо, положил руку на плечо человеку в пиджаке цвета хаки, прицелился и… выстрелил. Раздались два приглушенных хлопка. Беккер вначале как бы застыл, потом начал медленно оседать. Быстрым движением Халохот подтащил его к скамье, стараясь успеть, прежде чем на спине проступят кровавые пятна.

 - Мы сотрем всю переписку Хейла с Танкадо, уничтожим записи о том, что я обошел систему фильтров, все диагнозы Чатрукьяна относительно ТРАНСТЕКСТА, все данные о работе компьютера над Цифровой крепостью, одним словом -. Цифровая крепость исчезнет бесследно. Словно ее никогда не. Мы похороним ключ Хейла и станем молиться Богу, чтобы Дэвид нашел копию, которая была у Танкадо. Дэвид, вспомнила Сьюзан.
