 Homeostasis - Homeostasis is the tendency of an organism to regulate its internal conditions, regardless of external conditions. As humans, our body sweats when we are warm, the sweat on the surface of our skins helps to cool us down to, or to regulate our internal temperature. This is a picture of myself after a good workout. 

 Gymnosperm Leaf- A Gymnosperm is a plant that does not protect its seeds in an enclosure like a fruit does, and it does not flower. This evergreen tree leaf is an example of a Gymnosperm Leaf.

 Gymnosperm Cone- This is a cone (strobili) off of a Pine Tree, which is a Gymnosperm plant.

 

Adaptation of a plant- This plant has adapted to grow its leaves spread outwards on a flat plane to capture as much sunlight as it can in a shaded area. By doing so, it is able to survive with minimal sunlight on the bottom layer of this forest. Below is another view of this same plant from underneath.

 Exoskeleton- An exoskeleton is an external skeleton on an organism which protects it and provides the organisms support, unlike in us humans where our internal skeleton provides our support. This spider has an exoskeleton, along with most other insects.

 

 Radial Symmetry (animal)- This starfish has radial symmetry which can be determined by finding multiple planes of symmetry within an organism. Flowers have radial symmetry however starfish and the sand dollar are the two most common forms of radial symmetry within an animal.

 Endosperm- The endosperm is found inside the seeds of flowering plants and it is what makes up most of the mass inside the seed and provides nutrition to the embryo through starch. These corn kernals (for popcorn!) are an example of a seed which contains endosperm.
