BIO 1302 Unit III Homework (VC)

Instructions

Introduction

In the Unit III Lesson, you learned about the overfishing and decline of the Atlantic Cod off the coast of Nova Scotia. Other populations of fish around the world have been affected in much the same way. This activity will help you explore which species are imperiled by current fishing practices and which are, for now, a relatively sustainable choice for the table.

FIR 2302Unit III Homework Assignment (VC)

Instructions

In this assignment, you will write two letters using the letter template available here.

On the first page of the template, write a letter about empowerment addressed to a new rookie firefighter on your crew. Specifically discuss the empowerment of when and how to speak up, how to be tactful in speaking up to more seasoned firefighters or officers, and the importance of all firefighters watching out for unsafe practices. The body of your letter should be a minimum of 500 words.

On the second page of the template, write a letter to your company officer or a chief officer if you are a company officer addressing a situation where you or a peer could have been injured. In the fire service, these situations are commonly referred to as close calls, but solid situational awareness prevents a bad ending. You are required to explain the situation that occurred and identify recommendations to prevent it from happening again (e.g., training, equipment changes, or staffing issues). The body of your letter should be 500 words.

Your article review must consist of the following components:

• explain key terminology and religious practices,
• explain Prime Minister Abe’s tenets of Shintoism, and
• compare and contrast Chinese religions to Japanese religions.

Your reflection should be at least one page in length. You must include at least one outside source, which can be your textbook. Remember to use APA formatting throughout the assignment.
