sun‚ water‚ weather‚ and the Earth itself. Sing a Song about the Role of Plants! Teachers—download lesson plans to use in your classroom! Plants help the environment (and us!) in many different ways: Plants make food Plants are the only organisms that can convert light energy from the sun into food. And plants produce ALL of the food that animals‚ including people‚ eat. Even meat. The animals that give us meat‚ such as chickens and cows‚ eat grass‚ oats‚ corn‚ or some other plants. Plants

scientists in the AP Biology Development Committee have used their knowledge‚ discovered‚ and written down new AP Biology Principles that explains and guides you through biologically systems and how living things function. One principle states: Organisms use feedback mechanisms to regulate growth and reproduction‚ and to maintain dynamic homeostasis. In order to understand this biology principle‚ you must understand the operation of the feedback system‚ and how it is used to regulate growth‚ reproduction

Interactions with the environment- organisms are open system that exchange material and energy with their surroundings. 6. Energy and life: all organisms must perform work‚ which required energy.

variety‚ but living creatures can take in energy from the environment. This energy‚ in the form of food‚ is transformed to maintain metabolic processes and for survival. Life grows and develops. This means more than just getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured. Life can reproduce. Have you ever seen dirt reproduce? I don’t think so. Life can only come from other living creatures. Life can respond. Think about the last time you accidentally

According to many sources and credited opinions genetically engineering is scientifically dangerous and wrong. Genetic engineering is basically swapping‚ switching and getting rid of certain genes before creating a problemless child. Considering the parents choose to engineer their child the process would include extensive processes to inquiry the child’s natural genes. The many time consuming expensive tests would need to be done to make it possible to know which genes would be faulty in the child

MONERA • • • • • There are many different kinds of bacteria‚ but all of them belong to the kingdom Monera. A thousand bacteria can sit side by side in just 1 tiny millimeter. Despite their small size‚ bacteria are the most abundant of any organisms on Earth. Bacteria often get a bad reputation because they usually cause illness. Some bacteria doesn’t cause any harm‚ however some are beneficial.

Epigenetic Studies of Twins and Their Impact on Precision Medicine In a biological sense‚ DNA is the physical blueprint for a specific organism. Genes encoded in DNA directly transcribe specific phenotypes‚ such as brown hair or blue eyes‚ which individualize the physiology and behavior of an organism from others in its species. By comparing DNA base-pairs and coding sequences among humans‚ it was estimated that there is only 0.5% of interchromosomal difference between every living person on the
