Why are adolescence at higher risk of transmitting the most common STDs?
slavikrds [6]

Answer:

They are at higher risk because of hormones. During adolescence, you go through different hormonal changes, including sexual ones. These sexual changes may result in developing different urges such as masturbation. However, the problem comes with a lack of proper sexual education and how most of their knowledge on sex is based off of myths perpetuated by peers. So it's really a lack of education on sexual reproduction and the transmission of diseases.

Weight gain between the ages of 2 and 5 is about _______ pounds per year.
vovangra [49]

Weight gain between the ages of 2 and 5 is about five pounds per year.

A child's growth and development can be divided into four periods:

  • Infancy
  • Preschool years
  • Middle childhood years
  • Adolescence

Soon after birth, an infant normally loses about 5% to 10% of their birth weight. By about age 2 weeks, an infant should start to gain weight and grow quickly.

By age 4 to 6 months, an infant's weight should be double their birth weight. During the second half of the first year of life, growth is not as rapid. Between ages 1 and 2, a toddler will gain only about 5 pounds (2.2 kilograms). Weight gain will remain at about 5 pounds (2.2 kilograms) per year between ages 2 to 5.

Between ages 2 to 10 years, a child will grow at a steady pace. A final growth spurt begins at the start of puberty, sometime between ages 9 to 15.

The child's nutrient needs correspond with these changes in growth rates. An infant needs more calories in relation to size than a pre-schooler or school-age child needs. Nutrient needs increase again as a child gets close to adolescence.
