Text SolutionText solutionverified iconVerified

Oceans are least productive because
(i)  There is insufficient radiation as sunlight decreases with the increasing depth of the ocean.
(ii)  Oceans are nitrogen deficient which is an important nutrient for plants.
(iii)  Conditions of high salinity which is not favourable for all plants.
(iv)  There is no substratum to support plants.

54-Year-Old Female with a Defective Heart Valve Dr. El-Sheikh is a 54-year-old Egyptian female who complains of weakness, fatigue, shortness of breath, chest pain, and dizziness. Her heart rate is 96 beats/min, and her blood pressure is 148/54 mm Hg. You notice that she nods her head with every heartbeat, and her radial pulse is very strong and abrupt. Her heart sounds are abnormal, with a long diastolic murmur at the right sternal margin in the second intercostal space. Her doctor orders an echocardiogram, which shows that Dr. El-Sheikh has severe aortic regurgitation (backflow of blood through an incompetent valve) and an enlarged left ventricle. 5. The additional muscle in Dr. El-Sheikh's enlarged left ventricle means that it requires more oxygen. Which arteries are most important for supplying this ventricle?

ocss. The pigments are organised into two crete photochemical'light harvesting aplexes (LHC) within the Photosystem I (PS and Photosystem (PS II). These are named the sequence of their discovery, and not in esequence in which they function during the ht reaction. The are made up of ndreds of pigment molecules bound to teins. Each photosystem has all the pigments cept one molecule of chlorophyll a) forming ght harvesting system also called antennae] qure 13.4). These pigments help to make otosynthesis more efficient by absorbing Photon ierent wavelengths of light. The single chlorophyll molecule forms reaction centre. The reaction centre is different in both the tosystems. In PS I the reaction centre chlorophyll has an absorption ik at , hence is called P700, while in PS II it has absorption xima at , and is called . 6 ThE Electron Transport photosystem II the reaction centre chlorophyll absorbs elength of red light causing electrons to become excited and jump an orbit farther from the atomic nucleus. These electrons are picked yy an electron acceptor which passes them to an electrons transport
