Here we are providing case study questions for CBSE Class 8 Science Chapter 10 Reaching the Age of Adolescence.
Case Study Questions
Question 1:
Read the given passage and answer the following questions.
The changes which occur during adolescence in the human body are controlled by hormones. Hormones are secreted by glands called ductless glands or endocrine glands. The hormones are poured by the endocrine gland directly into the bloodstream. Endocrine glands include pituitary glands, thyroid glands, pancreas, and adrenal. The pituitary gland is also called the master gland because it controls the activities of other glands. In insects, metamorphosis is controlled by insect hormones. In the case of frogs, it is controlled by thyroxine hormones. When a person is suffering from sugar problems, it means that his pancreas is not producing sufficient quantities of insulin hormone.
Answer the following questions
i. What are hormones?
ii. Which gland is also called the master gland and why?
iii. Name the hormone which controls metamorphosis in frogs.
iv. What is the role of the pancreas in a diabetic patient?
Answers
i) Hormones are chemicals secreted by the endocrine glands that coordinate certain functions of the body
ii) The pituitary gland is also called the master gland because it controls the activities of other glands.
