excretory; respiratory
immune; reproductive

2:What is the difference between an artery and a vein?

An artery carries blood away from the heart; a vein carries blood to the heart.
An artery is responsible for carrying blood; a vein is responsible for gas exchange.
An artery is responsible for gas exchange; a vein is responsible for carrying blood.
An artery carries blood to the heart; a vein carries blood away from the heart.

3:The __________ system is made up of the nose, pharynx, trachea, lungs, bronchi, and alveoli.


4:Read the following summary, which describes blood flow and heart output in space. Then, answer the question.

The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

What process is being described?


5:The __________ system is responsible for moving blood cells throughout the body.

Which risk may result from having a cross-connection?


Cross-connections may result in backflow that causes the contaminants to enter the pure water supply under certain conditions. A backflow is a change of pressure in a water pipe that forces water to flow opposite to its intended direction, allowing contaminants to enter the unprotected system.

Final answer:

Cross-connections, which are physical links between clean and potential sources of contamination, present several risks primarily concerning health and safety. These risks include the transmission of diseases through contaminated water or medical equipment and electrical hazards in case of improper wirings.


A cross-connection exists when there is a physical link between a clean water source and a potential source of contamination. The risks associated with cross-connections primarily relate to the health hazards of consuming contaminated water, such as disease transmission, and possibly, complications ranging from gastrointestinal issues to fatal illnesses.

For example, in health care settings, a cross-connection might involve pathogens potentially introduced into the bloodstream via contaminated catheters, dental procedures, or wounds. This connection could lead to increased risk of diseases like Hepatitis B. In more severe scenarios, cross-contamination could lead to outbreaks like the one seen in the Flint, Michigan, water crisis, where pollution in the city's water system led to widespread health issues.

Moreover, cross-connections in electrical systems also present risks, like thermal hazards where excessive electric current causes undesired heating effects or shock hazards, potentially lethal electric currents passing through a person.

(01.07 MC)Josh would like to add swimming to his wellness plan, but he doesn't have a lot of experience with that activity. Which of the following represents a realistic plan he can follow to get started in the sport? Begin swimming five days a week for 10 minutes, aiming to complete 30 laps Begin swimming three days a week for 15 minutes, aiming to complete 10 laps Begin swimming two days a week for 45 minutes, aiming to complete 15 laps Begin swimming seven days a week for 20 minutes, aiming to complete at least 40 laps


Begin swimming two days a week for 45 minutes, aiming to complete 15 laps. The correct option is C.

What is wellness plan?

A programme that aims to promote and improve one's physical and mental well-being; typically supplied through the workplace, though insurancecompanies may also make them available to members directly.

Your company or plan may use the programme to provide you with premium savings, cash rewards, gymmemberships, and other inducements to sign up.

In recreational and competitive swimming, the body is propelled through the water using a combination of arm and leg actions as well as its inherent buoyancy.

It improves your cardiovascularfitness, muscular strength, and endurance while also assisting you in maintaining a healthy weight and heart and lungs.

Start swimming for 45 minutes, two days a week, with a goal of 15 laps.

Thus, the correct option is C.

Liquid A) an ionized gas of positively and negatively charged particles

Solid C) particles that slide past one another

Gas D) particles spread far apart that move around freely.



Liquid --> C.)

Plasma --> A.)

Solid --> B.)

Gas --> D.)

Liquid - A) particles that slide past one another  

In a liquid, the particles are close together but have enough energy to move and slide past one another. This allows the liquid to take the shape of its container. Think of pouring water into a glass - it takes the shape of the glass but still stays together as a liquid.  

Plasma - C) an ionized gas of positively and negatively charged particles  

Plasma is a unique state of matter that occurs at extremely high temperatures. It is often found in stars, lightning, and fluorescent lights. In plasma, the atoms become ionized, meaning they lose or gain electrons, resulting in positively and negatively charged particles.  

Solid - B) particles packed closely together that vibrate in place  

Solids have tightly packed particles that vibrate in place. The particles are held together by strong forces, which is why solids have a fixed shape and volume. Examples of solids include a rock or a piece of wood.  

Gas - D) particles spread far apart that move around freely  

Gases have particles that are spread far apart and move around freely. They have no fixed shape or volume, and they fill the space they are in. Examples of gases are air, oxygen, and carbon dioxide.
