The Power of Sports to Change the World
Sports are generally seen as a form of entertainment. However, there are many examples of how sports can break down barriers like racism. Your driving question for this project is: How can sports be an agent of social and/or political change?
In a May 2000 speech Nelson Mandela (former president of South Africa) stated, "Sport has the power to change the world. It has the power to inspire, it has the power to unite people in a way that little else does. It speaks to youth in a language they understand. Sport can create hope, where once there was only despair. It is more powerful than governments in breaking down racial barriers. It laughs in the face of all types of discrimination."
The goal of the project is to research an instance of sports helping to change the world for the better, then create some type of presentation that illustrates the story that you have researched and the impact it has had in the short- and long-term. Your presentation can be a poster or some type of tabletop display. It can also be a PowerPoint, Prezi, or other type of multimedia presentation.

Examples
Here are some examples of how sports has been an agent of change in the world.
South African rugby team that helped bridge the apartheid division between blacks and whites - depicted in the movie Invictus. This is probably my favorite story about how sports can have an impact on the world.
Texas Western basketball team that started 5 African-Americans in the national championship game vs. Kentucky - depicted in the movie Glory Road.
Special Olympics
HEROS Hockey
In Zanzibar, soccer is opening up opportunities for girls.
Coaches Across Continents
You will not have to look to hard to find examples of how sports have helped to change a community or a country. It happens every day in places around the world. This is more than just an "Inspired by Sports" assignment. It shouldn't be a story about an individual unless you can somehow show how that individual's experience has helped to change the world around him/her.

Match the exercise with the muscle or muscle group it exercises.

Answers

Answer:

Leg Raises ⇒ Abdominals

The raising of and return of the leg motion contracts and relaxes the abdominal muscles thereby exercising it.

Pushdowns ⇒ Triceps

The triceps are activated during motions that require the arms to push so pushdowns work the triceps.

Bench Press ⇒ Pectorals

This is one of the most effective and popular exercise for the pectoral muscles of the chest. It is also very effective for the triceps.

Machine Back Press ⇒ Shoulders

Using this machine activates the shoulders. As the shoulders are not very large muscles, care must be taken when using this so as not to overtax the shoulders.

Why is it important for an adolescence to know how pregnancy occurs in the female body?

Answers

It's important because then she is going to have to do lots that she may not be ready for weather it's emotional physical or social.

Explanation:

Answer: Every year, an estimated 21 million girls aged 15–19 years in developing regions become pregnant and approximately 12 million of them give birth.1 At least 777,000 births occur to adolescent girls younger than 15 years in developing countries. 2

The estimated global adolescent-specific fertility rate has declined by 11.6% over the past 20 years.5 There are, however, big differences in rates across the regions. The adolescent fertility rate in East Asia, for example, is 7.1 whereas the corresponding rate in Central Africa is 129.5.5

There are also enormous variations within regions. In 2018, the overall adolescent fertility rate in South-East Asia was 33.6 Rates, however, ranged from 0.3 in Democratic People’s Republic of Korea to 83 in Bangladesh.5

And even within countries there are enormous variations. In Ethiopia, for example the total fertility rate ranges from 1.8 in Addis Ababa to 7.2 in the Somali region with the percentage of women aged 15-19 who have begun childbearing ranging from 3% in Addis Ababa to 23% in the Affar region.7

While the estimated global adolescent fertility rate has declined, the actual number of child births to adolescents has not, due to the large – and in some parts of the world, growing – population of young women in the 15–19 age group.8 The largest number of births occur in Eastern Asia (95,153) and Western Africa (70,423).9

Sophia while playing with her dolls is demonstrating his brother the gender identity. According to her, only girls play with dolls, not boys. Thus, the correct option is B.

What is Gender identity?

Gender identity is an individual's internal and individual experience of the gender. It is a person's sense of being as a woman, a man, or both, neither, or anywhere along the gender range. A person's gender identity may be the same or different from the one of their birth-assigned sex.

Biological factors which may influence the gender identity include pre- and post-natal hormone levels and the genetic composition. Social factors include the ideas and beliefs regarding the gender roles conveyed by the peers, authority figures, mass media, and other influential people in a child's life.

Therefore, the correct option is B.
