This picture represents evolution by giving a visual sequence showing how we as humans evolved from ape-like ancestors. Each organism in the picture represents a small change of traits that have been developed and pass down over the generations. You can see the subtle changes in things like posture, body size and headships. It also shows how these organisms adapted overtime to better survive in their environments. It also reflects a key part of evolution know as "descent with modifications." Not only have humans evolved, but every species once came from a different ancestor that inherited traits in order to survive. This process, that is still on going, helps to explain the diversity we see on Earth today.

Naegleria Fowleri is a protist most commonly found in warm freshwater lakes, rivers and hot springs. You've probably heard of it through it's more common name "the brain eating amoeba." It gained its name because if this amoeba is enters ur system when water goes into your nose it can cause serious damage. Infections are very rare, but if you happen to encounter this protist it progresses very quickly and is usually fatal. Symptoms of this infection include headache, fever, nausea, and vomiting. As the infections progress you may also experience stiff neck, confusion, lack of attention, loss of balance and hallucinations. Typically, after 5 days it will result in the patient being in a coma. Scientists are still working to find effective treatments to fight this deadly infection.

Grass – Has fibrous roots and parallel veins, making it a monocot.

Sunflowers – Have 2 cotyledons, branched veins, vascular tissue in a ring, a taproot, and flower parts in multiples of 4 or 5, making them a dicot plant.

Corn – Has parallel veins, flower parts in 3s, and fibrous roots, making it a monocot plant.

Oak trees – Have 2 cotyledons, branched veins, a taproot, small flowers typically in groups of 4 or 5, and vascular tissue in a ring inside the trunk, making them a dicot plant.

Peanut plant – Has branching veins, 2 cotyledons, and a taproot, making it a dicot plant.

Onion – Has one cotyledon, parallel veins, fibrous roots, flower parts in 3s, and scattered vascular bundles, making it a monocot.

Peach trees – Have 2 cotyledons, branched veins, a taproot, vascular tissue in a ring, and flowers in 5s, making them a dicot plant.

Lilies - have 1 cotyledon, parallel veins, fibrous roots, and flower parts in 3s, making them a monocot plant.

For my assignment I choose to find a video on Echinoderms and learn more about them. The word Echinoderm is latin and stands for "spiny skin." One of the most famous Echinoderms, is the starfish. Echinoderms live in the ocean and are all invertebrate. All echinoderms have radial symmetry, meaning that you can split their bodies into 5 identical parts. They also have something called tubed feet; they are small and tube like and part of their water vascular system. They are useful in the act of moving, breathing and eating. Some Echinoderms have chemical defenses, while others have spiny skin or a bad taste in order to protect themselves from predators.

Homeostasis is how the systems within our bodies regulate and maintain themselves. It helps are bodies be able to adjust in order to keep the balance and help recover from injuries and illnesses. It keeps things like temperature, fluid balance and oxygen levels stable. There are two main ways homeostasis works: positive and negative feedback. Most homeostatic processes use negative feedback, this is where the body detects a change and reverses it. This includes things like sweating to cool down or shivering to warm up. The other process is positive feedback, this is where a process will amplify itself until a specific outcome is reached. Examples of this include child birth or blood clotting. Overall, homeostasis is essential for the body systems to be balanced and preventing harm from too much or not enough of vital substances.

Parkinsonism is a syndrome that causes problems with movement such as tremors, bradykinseia (slow movement), muscle stiffness and posture instability. In order to be diagnosed with Parkinsonism at least 2 out of the four symptoms have to be present. There are many things that could cause Parkinsonism, such as strokes, brain tumors, certain drugs, and/or other brain problems that affect dopamine pathways. However, Parkinson's disease itself is a specific condition. It happens when the nerve cells in part of the brain called substantial nigra lose their color and develop clumps called levy bodies. Parkinson's is the most common cause of Parkinsonism. Doctors diagnose this disease by looking at a persons symptoms, not through labs tests or scans.

I choose a picture of the Arctic tundra. This biome is known for its long, harsh, very cold winters. Summers in this biome are short and cool. The vegetation in this biome is low-growing, including mosses, lichens, and grasses. The wildlife includes animals that have adapted to the cold climate. Examples of these animals are Arctic foxes, polar bears, and migratory birds. Biodiversity is especially low in the Arctic tundra. Overall, this biome has harsh conditions that make life challenging for both plants and animals.

Biodiversity is the total variety of all living things on earth. This word summarizes millions of habitats, species, individuals and characteristics. High biodiversity is important because it keeps ecosystems secure and supplies us with food, medicine, and costal protection. Activities such as habitat destruction, overhunting, and overfishing, has caused many populations to drastically decrease, or even go extinct. The loss of biodiversity is happening very quickly with some species declining by over 75% in just a few decades. This not only effects nature, but also us humans. It is important that we are aware of this problem and take action to help prevent this loss of life.
