Which process is used by the skin to repair itself when you get cut claim, evidence, reasoning

Alex

Answer:

Wound Healing

Explanation:

Wound healing is the process whereby the skin repairs itself after injury. Wound healing can be divided into four overlapping processes; maintenance of homoeostasis, an inflammatory response, a proliferative phase, and remodeling.

How??....

Red blood cells help create collagen, which are tough, white fibers that form the foundation for new tissue. The wound starts to fill in with new tissue, called granulation tissue. New skin begins to form over this tissue. As the wound heals, the edges pull inward and the wound gets smaller.

On multiple choice questions, students cannot do that and he cannot give students partial credit. The teacher gives one class multiple choice questions and the other essay questions. He compares the scores after each class. Identify the: INDEPENDENT VARIABLE, DEPENDENT VARIABLE, HYPOTHESIS, EXPERIMENTAL GROUP, and CONTROL GROUP.

Essay question is the independent variable while the multiple choice is dependent variable. The hypothesis remains the fact that his thought about students performance in essay questions better than multiple choice questions, experimental group remains both essay and multiple choice questions and the control group is the essay question
