HELP ASAP! WILL GIVE 50 POINTS! In a paragraph, describe Who is primarily responsible for a young child’s self-esteem and how does this change as the person becomes a teenager

Answers

the parents are primarily responsible for a young. child's self esteem. Telling the child good job or paying attention lets them know that you care and are listening to what they're saying. A good way to help them is by encouraging them to try new things. This changes as they become a teenager because they have more freedom and don't feel the need to be babied anymore. As they become a teenager they begin to try and experiment on their own.

Answer:

Explanation:

Technically there are only three people in charge of boosting a child's self-esteem. The two parents, and the child themself. But as the child grows older, they tend to allow others into their emotions allowing others to boost or destroy their esteem. As the child becomes a teenager, the people he/she let into their lives can affect the child's behaviors as well.

What is the importance of calculating your BMR

Answers

Answer:

"Knowing your Basal Metabolic Rate is important whether you want to maintain your weight, lose weight, or even gain weight. Your BMR can help determine what number of calories you should be eating in order to meet your goals. If you want to lose weight, you will need to eat less than your BMR (or maintenance calories)"

"The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers"

so basically its the energy that requires your body to work while you sit idle.  but the reason above is the importance of caculating the BMR. This is what I researched, but feel free to look more in depth about it if I didnt clear it up :)

Explanation:

"Your Basal Metabolic Rate (BMR) is the minimum level of energy your body needs when at rest to function effectively including your respiratory and circulatory organs, neural system, liver, kidneys, and other organs (you even burn calories when sleeping).  About 70% of calories consumed every day are used for your basal metabolism."

Despite condom use, there remains a 15% risk of sexual transmission of HIV/AIDS, a 50% risk of chlamydia (a cause of female infertility) and a significant risk of human papillomavirus (HPV) (cause of cervical cancer). Some STDs can be passed on by skin-to-skin contact in the entire genital area, only part of which is covered by a condom.
