The increase in size or weight of an animal. The reason is because for multicellular organisms, most major evolutionary change proceeds by alterations in the pattern of growth, development, and maturation. By understanding the processes related to animal growth we can alter true growth and fattening as a result of growth rate. .������k@ ��奿�cm@ш��C9b�X�ވc�A{5oV��~I���s-�n+��ʛ���� 7]=A�|�)L9B�T0��7\��;捻�W �F�gL�����+�,[,��+�X[����7�,W!G80�$i�N8�u���j��}�w��x!$�kf��C輄��8D��8���3��3��G�@��롐�?�g�!��@�4dE�=4 �7�/�U���� . << /Length 5 0 R /Filter /FlateDecode >> 1.4.

Hormones • Sex hormones – Testosterone (other androgens such as androstenone and adrenal androgens) • Increases bone growth • Shortens G1 phase • Increase protein synthesis – Estrogen • Facilitates fat deposition • Stimulate muscle growth • Very anabolic in ruminants • Growth Hormone or Somatotropin – Major action is to the production of Insulin –like Growth %��������� PRINCIPLES OF HUMAN DEVELOPMENT Developmental psychologists believe that knowledge of an accurate pattern of development is fundamental to an understanding of children. Harvest Processes for Meat 8. Therefore, all students will receive full virtual instruction until further notice. These include hyperplasia, or increase in cell number due to cell proliferation (cell division or mitosis) and recruitment from stem cell populations; hypertrophy, or increase in the size of cells; and differentiation (precursor cells achieving mature functioning— often this process cannot be reversed).
