Role of Stomata & Control Stomata : a pore found in the epidermis of plants which are used to control as exchange Main function of stomata : Allow enough C02 to enter the leaf to optimize photosynthesis‚ while conserving as much water as possible Structure of stomata * Each stomata consists of a stoma (minute pore) which are surrounded by 2 guard cells. * Stomata closes and opens according to the turgidity of the guard cells * Stomata also allows for cooling of the leaf by loss

Pg. 287 #1‚3‚4 1. Describe the structure of a nucleotide. A nucleotide is a sugar molecule that has 3 parts including a simple sugar‚ a phosphate group and a nitrogenous base. Nucleotides join together forming long chains‚ with the phosphate group of nucleotide bonding to the deoxyribose sugar of an adjacent nucleotide. 3. Explain why the structure of a DNA molecule is often described as a zipper. The structure of a DNA molecule is often described as a zipper because it is made of tow chains

ENZYME STRUCTURE AND FUNCTIONS: Enzymes are biological catalysts. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures Definition of enzyme: A protein with catalytic properties due to its power of specific activation is defined as an enzyme. STRUCTURE Enzymes are proteins their function depends on its complexity. The reaction takes place in a small part of the enzyme

Role of Brain in Cognitive Functions Cathy Moyer-Larsen Role of Brain in Cognitive Functions Cognitive brain functions enable the ability of the brain to attain information in a meaningful way. Cognitive psychology is what happens in the mind. Two important conditions concerning the ability to use cognitive brain functions is the current mood and health (Willingham‚ 2007). Cognitive functions originate in the part of the brain called the cerebrum. Majority of brain mass is in the cerebral

result in the death of the human being. From the Brain-Death theory‚ death is defined as an irreparable cessation of brain function. Therefore‚ it follows that a fetus becomes a human being when it possesses the essential property of a human being that is‚ having a brain that has not suffered irreparable cessation of function. To reinforce this conviction‚ he added that by the sixth week of conception‚ when the fetus possesses a functioning brain‚ all the other properties that are required for being

Question 1 Given what we know about localization of function in the human brain‚ is it scientifically legitimate to categorize people as left-brained or right-brained? Hemispheric lateralization‚ as discovered by Roger W. Sperry (1965)‚ ascribes to the specialization of one cerebral hemisphere or the other in controlling specific functions (Passer‚ Smith‚ Holt‚ Bremner‚ Sutherland & Vliek‚ 2009). In recent years‚ there appears to be a growing phenomenon in the generalization
