Fat´s structural role is particularly important in the brain, which is 60% fat.
The brain is the fattest organ in our bodies and consist of at least 60% fat.
B. Protective Factors
I would say that the answer is B because when your life is in risk, you need someone with you to stay and make sure everything is okay.
Some parts of out body itch because of many reason they might be
•Dry Skin
•Bug Bites(bedbug/lice/scabies)
•Itchy skin condition
•Allergic reaction
•Skin Cancer
•Warning of a disease (Diabetes/HIVetc)
(There are other reasons too like:
•Reaction to plants and marine life(poison ivy/other plants you might be allergic to/water/pond)
•Nerve Problem)
Anyways it ming not be something to be afraid of because sometimes my skin too itches without any reason. It can be that we have a dry skin. But if you want to you can go to a dermatologist. Just remember that it is okay to have some rashes and itches. Stay safe
1. Use your brain
Take breaks between homework and make sure you drink water in between breaks because that's how your brain refreshens. Also, be sure to think critically and don't just write down random stuff which will help you get past your homework. It's important to think through every step of the way in assignments and tests.
2. Use online webpages to help you
By this, I don't mean plagiarise because it violates one's academic integrity, but use the thesaurus to help you reword a phrase.
3. Read more
Reading can help you with writing because it's great to have a few more exemplars to guide you as you strengthen your writing path.
Good luck! This question wasn't that specific so sorry I couldn't narrow it down for you on what you specifically want to work on.
