Answer:

An antigen is any substance that causes your immune system to produce antibodies against it. This means your immune system does not recognize the substance, and is trying to fight it off. An antigen may be a substance from the environment, such as chemicals, bacteria, viruses, or pollen.

Create a list of words or phrases that can help describe your emotions and how you ſee about this extended time out of school​
topjm [15]

Answer:

Relaxed, Relieved, Happy, Worried

Explanation:

These four words best describe my emotions towards this extended time out of school as well as most students around the world. Since we are getting time out of school I am feeling happy because I have time for myself for what I love doing which allows me to feel relaxed. Also not having to have work to turn in every day makes me feel relieved. Yet, aside from all of these positive feelings I also feel worried about the reason for this extended time out of school and how it will affect my progress towards graduation.

____ [38]

Answer:

When you don't have proper body alignment, then the curl ups could be too easy or too hard.

This could also cause injury, due to improper stretching of the muscles.

Some tips would be: (<em><u>You may choose any two of them</u></em>)

1.) keep your feet about 12 inches/1 foot aways from your bottom.

2.) Stretch properly before doing curl ups to prevent injury.

3.) Lay on something soft to prevent spine aching/injury.

4.) Instead of putting your hands behind your head, put them in an X shape across your chest. This can prevent neck injury or aching.

5.) Don't let your feet lift off the ground, have a friend hold them down. Never put gym weights on them, as that can cause injury to your feet.

In a minimum of 3 paragraphs answer the following question: List four benefits of a specific type of physical activity. Briefly
eduard

Answer:

Running Is a very important physical activity. It is needed in everyday life, and it should be practiced to keep your body healthy. Younger children should run a lot, that's why sports are so encouraged in school.

  Running can significantly improve physical and mental health. As a form of aerobic exercise, running can reduce stress, improve heart health, and even help alleviate symptoms of depression. Some researchers think running may be so good for us because it's something we evolved to do.

  Even only running for 30 minutes is great for you. One 30 minute run is guaranteed to burn between 200-500 calories. That's a fantastic step forwards to your weight loss goal. Or a guilt-free guilty pleasure that day. Or splitting the bottle instead of having a glass.
