These adaptations allow survival in changing conditions. 
The picture below shows leaves with a drip tip which allow rain drops to run off quickly. Plants need to shed the water drops to avoid growth of fungus and bacteria and ruining the development of it. This adaptation allows it to live longer and produce more offspring than other individuals. This reproductive success achieved by adaptations results in a change in the characteristics of a population through a period of time, known as natural selection. The frequency of traits in populations and species being changed is called evolution and is dependent on adaptations of individuals of a species.]]> 2018-09-09 20:59:05 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200367 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200374 Organisms respond to stimuli by moving away or toward from a stimulus. 
The movement of an organism by choice or in response to a stimulus is also a part of its behaviour. In the example below, I am responding to the external stimuli being the smell of soup by moving towards it.]]> 2018-09-09 20:59:09 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200374 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200392 An organism's growth is recognized by an increase in size and usually the number of cells is part of its development.
 In this example, my plant has grown from a seed in a pot into a tall adult plant with beautiful green leaves. This represents the development of an organism and especially its growth in size and an increase in the number of cells. Development also includes repair that would take place following an injury of some kind to the organism.]]> 2018-09-09 20:59:19 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200392 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200408 Organisms acquire energy and materials to carry out their activities. 
Food is the material and energy for humans and other animals. The photo below displays myself consuming food, in this case an apple for nutrients being Vitamin C. Our cells use energy from the nutrient molecules to do everyday tasks from moving to lifting objects. Certain nutrient molecules are broken down to provide energy to carry out synthetic reactions as well. ]]> 2018-09-09 20:59:22 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200408 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200414 Organisms are organized in a hierarchy of levels.
 For the picture below, this tree represents the organism. The organism is the highest point in the hierarchy level containing organ systems. Typically in the lowest level of organization, atoms are at the bottom of the spectrum. Then they join to form molecules, DNA molecules in this tree example, which are found in cells. Cells are the smallest unit of life that can differ in shape, function and size. In this case the cell is known as a plant cell. These cells will form a group and become tissues, leaf tissues for this example. Tissues will perform a certain function and combining tissues together will form an organ. In this case, the organ is a leaf. Organs will work together to form an organ system and allow the organism to function.]]> 2018-09-09 20:59:25 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279200414 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279202959 An organism's genetics carry genetic information for organism reproduction. Our DNA contains hereditary information that guides cellular functions and life's activities. Unicellular organisms reproduce asexually by dividing. The new cells will remain having the same genes and structure of the single parent. Multi cellular organisms mainly reproduce sexually such as humans. A parent being male and female contributes to about a half of their own genes to their offspring.
 The picture of my family below is an example of organism reproduction.]]> 2018-09-09 21:26:46 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279202959 FernandoN9999 https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279205475 The organism's internal environment of an organism remains relatively constant is known as maintaining homeostasis. 
The photo below shows me sweating and represents the human body internal temperature being affected by external temperature and trying to revert to normal internal temperature. Our organ systems in our body work together to help maintain homeostasis and stay healthy.]]> 2018-09-09 21:52:44 UTC https://padlet.com/FernandoN9999/jzswnd8weirs/wish/279205475
