Answer:

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

When is it okay for a client to become intimately involved with their trainer? A. If both parties consent to it B. Never C. If t
mrs_skeptik [129]

Answer:

B. Never

Explanation:

Personal trainers (PT) are individuals hired to improve the fitness (mostly by exercise or dieting) of another person, known as the client. Not only do personal trainers possess the skills and knowledge to go about their jobs, they are also certified, hence, making them professionals at what they do.

Series of conversations, sometimes personal can occur between the PT and the client in order to extract information needed to successfully help the client. However, a personal trainer is mandated to be PROFESSIONAL while performing this role. One of the professional ethics of the job is that personal trainers are NEVER to get into any intimate relationship with their clients. This is a serious offence that can cost a trainer not only his/her job but also professional license.

which of the following shows the levels of organization in a multicell organsim from the smallest level to the largest?
zzz [600]

1. Organelles-. e.g. mitochondria, nucleus.

2. Cells- e.g. epithelial cells, palisade cells. 

3. Tissues- e.g. muscles, connective tissue.

4. Organs- e.g. heart, liver.

5. Organ systems- e.g. digestive system, circulatory system

This is because there are many organelles inside a cell and  a collection of same cells that creates tissues, a collection of tissues form organs, to carry out a particular function, and a collection of organs working together is an organ system. I think this is what they're after as I had a similar question a little while ago.
