The four organ systems that I chose were skin, muscles, eyes and ears. For each of these systems, we drew a scientific diagram. Skin The skin is covered over the body, called the integumentary system. It protects the body from injury and disease caused by bacteria and various viruses. Skin also helps to maintain body temperature are keeps cells from drying out. This is a very important organ system so the body can stay safe from harm and danger. Muscular System There are three different kinds of muscles. Cardiac muscles, skeletal muscles, and smooth muscles. They are located in various different places of the body such as arms, legs, and even eyes. They help perform some of the body's movements such ...

Mutations are not planned or done purposely, but GMOs are modified for specific different reasons from harmful viruses to better tasting fruit.  What are Mutations? A mutation is a change of genetic material. There are two ways that Mutations can occur. The first way is by external factors. These are caused by radiation, pollution, or chemicals. Then, there are internal Factors which are errors that get bigger over time such as DNA that fails to copy accurately. Now you may be thinking, “Can I make a mutation?” Mutations are random, meaning that you cannot decide when they will occur. Mutations can have positive and negative effects that happen right away or over a long period of time. There are two different kinds of mutations. There are gene mutations and chromosome mutations that have differe...

Cheetahs live mainly in grasslands and areas with bushes and trees in some parts of Africa and the middle east, but you may have trouble finding one because they are very close to extinction. Less than 10,000 cheetahs are left in the wild. This is because of loss of habitat, and less prey to eat which threatens the loss of these beautiful creatures. The scientific name for a cheetah is  Acinonyx jubatus. The family name of cheetahs is Felidae. Their lifespan can be from 10 - 12 years, depending on the different conditions of prey, habitat, and weather. They eat carnivores such as  gazelles, impalas, which is a medium-sized antelope, and smaller hoofed animals in their habitat, though they can also eat rabbits, birds, and other small animals. The cheetah is the f...
