Carbon-14 can be used to determine the age of a dinosaur egg. True False
kozerog [31]

Answer:

FALSE

Explanation:

But carbon-14 dating won't work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.

We can conclude that, Barbie's choices are <u>egocentric</u> which indicates her being in the <u>preoperational stage</u> of Piaget's theory of cognitive development.

People who use a biopsychosocial approach are most likely to gain a: <em>comprehensive understanding of an individual's development.</em>

<em />

<h3>What is the Preoperational Stage?</h3>

The preoperational stage is the second stage in Piaget's theory of cognitive development, which is characterized by:

  • Egocentrism
  • Symbolic representation

The preoperational stage begins from 2 years of age up to 5 years of age. At this stage, children tend to use symbols to represent their own world.

According to Piaget, children tend to be egocentric during the preoperational stage, which explains why Chloe will get a gift like a Barbie doll for her dad. This shows Chloe, at this stage, cannot understand that her dad think in a different way she thinks.

Therefore, we can conclude that, Barbie's choices are <u>egocentric</u> which indicates her being in the <u>preoperational stage</u> of Piaget's theory of cognitive development.

<h3>What is the Biopsychosocial Approach?</h3>

In psychology, the biopsychosocial approach is a wide approach that takes into consideration biological, social, and psychological factors, and how they interact to influence health care delivery, illness and health.

Therefore, people who use a biopsychosocial approach are most likely to gain a: <em>comprehensive understanding of an individual's development.</em>
