Question 2

The common garter snake (Thamnophis sirtalis) is found throughout North America. In the South, it is active year round. In the North, it is active during the warmer months but hibernates during the winter. It is commonly found basking on warm rocks during cool mornings. This lifestyle indicates that the snake is probably

Accepted Answer

The common garter snake is ectothermic, meaning it relies on external sources of temperature to regulate its body heat, as indicated by its basking behavior and seasonal activity patterns.

Question 3

You are given a sample of tissue to identify. The cells contain large amounts of protein arranged in stripes. When an electrical charge is applied to it, the tissue twitches and then relaxes. You classify this sample as__________ tissue.

Accepted Answer

The description of cells with large amounts of protein arranged in stripes and the ability to twitch upon electrical stimulation are characteristic features of skeletal muscle tissue. These stripes are due to the arrangement of actin and myosin proteins in the muscle fibers, which are responsible for muscle contraction.

Question 13

While working in a forensic lab, you are given a bit of tissue to analyze. It has several layers. The upper surface consists of dead, flattened cells. As you move deeper into the tissue, the cells look healthier. The bottom layer of cells is actively dividing. Under the dividing layer is an acellular protein goo. You identify the sample as__________ tissue.

Accepted Answer

The description matches stratified epithelial tissue, which is characterized by multiple layers of cells with the most superficial layer consisting of dead, flattened cells and deeper layers showing progressively healthier cells, with the bottom layer actively dividing. The "acellular protein goo" mentioned is likely referring to the basement membrane that underlies epithelial tissues.
