Retrieve your animal tissue specimens. If you have an Edmentum lab kit, your specimens are frog skin, human cardiac (heart) muscle, and human red blood cells. As you did with the protist slide, start with the lowest magnification and record what you see. Identify the structure of the tissue and whether you can see any individual cells and cell structures. Repeat with the next two magnification settings. In the answer space, write down what you observed for each sample under each magnification.

The frog skin is first dissected from the frog and then observed under the microscope.

Explanation:

The skin has squamous epithelial cells when viewed under the microscope. The squamous epithelial cells are flat and irregularly shaped that are arranged in thin layer.

Human cardiac muscle under the microscope looks striped and are involuntary in nature. Human red blood cells appears as disc shaped and red in colour. It does not contain nucleus and performs function of oxygen transport.

One is the squamous epithelial cells and the other one is the involuntary muscle cell.

Explanation:

From the microscope layout, it can be seen that the frog skin consist of the squamous epithelial cell arrangement. In other words, the frog skin consists of a one-cell layer that is under the skin. This single layer is responsible for the respiration and transport of the toxins out of the body. It is the single epithelial layer that gives the cell its soft structure.

On the other hand, the tissue from the cardiac muscle will be hard and rough. This is the striated muscle cell. These cells are adapted to such because they involve a lot of muscle when pushing blood to the extremes.
