The new IB Economics syllabus and curriculum for 2020 is listed below, for first assessment in 2022. In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of hydrogen carriers, liberating carbon dioxide. Arteries convey blood at high pressure from the ventricles to the tissues of the body. Other gases including methane and nitrogen oxides have less impact. A nerve impulse is only initiated if the threshold potential is reached. The genome is the whole of the genetic information of an organism.

Global temperatures and climate patterns are influenced by concentrations of greenhouse gases. Ex situ conservation is the preservation of species outside their natural habitats. The left cerebral hemisphere controls muscle contraction in the right side of the body and vice versa for the right hemisphere. Membrane proteins are diverse in terms of structure, position in the membrane and function. Some genetic diseases are sex-linked. Light energy is converted to chemical energy in carbon compounds by photosynthesis. Bipolar cells send the impulses from rods and cones to ganglion cells. Metabolic pathways consist of chains and cycles of enzyme-catalysed reactions. The receptor–hormone complex promotes the transcription of specific genes.

Psychoactive drugs affect the brain by either increasing or decreasing postsynaptic transmission. %PDF-1.3 Rods and cones differ in their sensitivities to light intensities and wavelengths. All organisms are classified into three domains. Veins collect blood at low pressure from the tissues of the body and return it to the atria of the heart. Malnutrition may be caused by a deficiency, imbalance or excess of nutrients in the diet. Microorganisms are used in industry because they are small and have a fast growth rate. Autotrophs convert carbon dioxide into carbohydrates and other carbon compounds. Differentiation involves the expression of some genes and not others in a cell's genome. The distribution of species is affected by limiting factors. Fusion of gametes results in diploid zygotes with two alleles of each gene that may be the same allele or different alleles. ��?2�\�z��T�ɵ{�xH��[email protected]� ������X�P�=��k��={�+�9r&��s=��.9��o��>]M`�S��}N=[��r�M�v�@��Ap�1� Q �̦�oU�X�/� ��a(\�����o�� ���UMkj\�ŢL�kBl�f��9!ؘ����<3��:ܘ�_W�2/�e!d!$����`�S"�����IpEq)8�^w�dјY�����2�S�W˳�Ek��\�yQX� ӖK՘^��������������g�NL�Ҽ:���7_������͛� bش�հ�u�FPu\��vX�hm �(��qa���n`E �2���o��ij��"o�6 H�[email protected]` nҖ�e��E�p8 �\].EZu&�g�Ap�Ty��j3�Vc˨efZ`��Vޅ�� @���f��Ƽ�+o��?Hzz�*��&P���+�/ ��'�N�5�d������q���@xF2��>�+����~$)�nω|±��c�f��K�+��w��sM�0��Ћ����&�kM�j�T��G�ߓkb>�>�m��>�n��|�%>0ێ�L���g���� g���V��R����?0�Q��%BB"�(�Eݒ��os�S������> Ӊ�΀⇹9��fAB�͈,��Ue����i�[� The composition of blood in the renal artery is different from that in the renal vein.
