Answer: Hypothalamus
The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.
Explanation:
Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:
- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics
- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.
Thus, hypothalamus plays important role in puberty

Answer:
What does a linear velocity graph tell us?
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
What is an acceleration time graph?
A graph that shows acceleration plotted against time for a particle moving in a straight line. ... The acceleration-time graph is the graph y=a(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards.
graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.
Explanation:
Answer: Option D
Explanation:
Once the pathogen enters the body, it starts dividing and after a certain period of time the patients experience some sign and symptoms of illness.
The prodromal period occurs just after the incubation period. In this phase the pathogen keeps on dividing and the host begins to experience general symptoms and signs of illness.
This is a result of the activation of immune system of the body which results in the swelling, pain, soreness.
