Do you think Millersville University was justified in disqualifying Stacy from earning her teaching degree because of her profile page?

Answers

Answer:

Absolutely not

Explanation:

Stacy was a legal adult at the time she was in the photo. She was drinking out of a plastic cup that could have had anything in it. The contents of the cup were impossible to know from the photo. The argument that it could have upset her students is a very invalid one. Most children have seen their parents drinking on occasions throughout their lives. I do believe that teachers are held to a higher standard, but what they do in theor private lives should be their decisions as long as it is completely legal and not vulgar or discriminative.

why do you tink it is important for all you to learn about whom you can goto for your own needs and the needs of your family​

Answers

Answer:

Explanation:

Knowing who to go to can always help with your self esteem and how you present yourself as a person. Talking about your problems and asking for help with family things isn't something to be ashamed of. Just remember to talk to people YOU trust. When it comes to you not knowing who to talk to about something that you don't really want certain people to find out about, asking your doctor to talk is really helpful, seeing that they have sworn the Hippocratic Oath, and all things you tell your doctor are confidential, meaning they can't share them with anyone else, but you and those you give permission to be told. Calling helplines just to rant is not illegal, and that is what they are there for, they're not just for those wanting to commit or anything like that, you can talk to them about any problems you need. If your cupcake fell on the ground and it upset you, you could even call and talk about that! Just remember that there is always someone out there for you, and keeping things inside is NOT the way to go.

I hope this helps you, have a great day!

Define the term public participation and mention THREE ways in which the soweto protestors harmed their community it their attempt to be public participants

Answers

In the Soweto protest, public participation with only white people made the education of blacks difficult and inappropriate.

The Soweto Uprising

The Soweto Uprising was one of the bloodiest episodes of black rebellion since the early 1960s, sparked by the police crackdown on the June 16, 1976 march to protest the inferiority of "black schools" in South Africa.

The South African segregationist system, instituted in the late 1940s, forced blacks to pay to attend schools with overcrowded classes and poorly qualified or even inferior teachers, while education for whites was free.

Public participation

Public participation is a way for the government to capture information, ideas and perspectives from across society, potentially lowering the costs and increasing the effectiveness of official research, public policy development, service provision, monitoring, review and evaluation.

explain why vitamin and mineral pills by themselves are not sufficient for good health

Answers

Answer:

 Vitamins A, D, E and K are fat soluble, which means they are stored in the body and if taken in high doses can be toxic. High doses of some water-soluble vitamins, such as vitamin B6, can also become toxic.

Most people do not need to take vitamin supplements and can get all the vitamins and minerals they need by eating a healthy, balanced diet. Vitamins and minerals, such as iron, calcium and vitamin C, are essential nutrients that your body needs in small amounts to work properly.
