Answer:
1. The reason I think that the rattlesnake might be in danger of being stepped on is that it like every other snake has to slither on the ground in order to relocate its-self to another place. If the environment were to change then the snake could be in a lot more danger because if the environment were to change it could cause food shortages and it could cause habitat destruction. The reason why I think that natural selection would make it more likely to be stepped on is because of the rattlesnake's camouflage that can make it blend in with its surroundings. This what can make it be stepped on accidentally.
2. The forces that were in the rattlesnake's favor were that in its natural habitat it enables it to blend in with its natural surroundings. The thing in the environment that might have changed is food and if there was a natural disaster this could make that happen. The way that this can affect whether the rattlesnake is a favorable or unvaforable characteristic is by it if it wasn't then it wouldn't be able to survive in its habitat, but, This rattlesnake is favored by this characteristic because it's able to survive in this habitat.

The cartilage that is located at the end of long bones that closes when growth ceases is called the Hyaline cartilage. Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix. Chondrocytes plays a major role in the organization of extracellular matrix, which is responsible for the biomechanical properties of cartilage tissue. A region of hyaline cartilage remains over the surface of the epiphysis as the articular cartilage and another area of cartilage remains between the epiphysis and diaphysis.
The epiphyseal plate is the area of growth in a long bone. It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed.
