Question

16.(14.5)the human body is organized in a hierarchical arrangement, as shown below. what structure is represented by the first image?a. organ systemb. tissuec. celld. organ18.(14.5)sensory cells in the human eye can detect changes in light. the information obtained from these sensory cells is transmitted to the brain through neurons, and the brain determines the correct behavioral response.for example, if the intensity of light being detected by a persons eye rapidly increases, the nervous system might transmit information to the eye that causes the eyelid to close and block out the light. this is an example of a behavioral response that......a. requires communication between several individual organismsb. must be completed by a single cellc. requires communication between cells and an organ systemd. is not influenced by an organisms environment

Explanation:

Step1: Identify body hierarchy order

The human body hierarchy from simplest to most complex is: Cell → Tissue → Organ → Organ System → Organism. The first image is the smallest, simplest structure, so it is a cell.

Step2: Analyze question 18's scenario

The response uses sensory cells (cells) and the nervous system (organ system) to communicate, so it requires interaction between cells and an organ system. Eliminate A (no multi-organism interaction), B (needs more than one cell), D (triggered by environmental light change).

Answer:

1. C. Cell
2. C. Requires communication between cells and an organ system
