1) Facial Hair Growth: One primary secondary sexual characteristic that differs between males and females is the growth of facial hair. During puberty, males typically experience an increase in the thickness and distribution of facial hair, including the development of a beard and mustache. This isRead more
1) Facial Hair Growth:
One primary secondary sexual characteristic that differs between males and females is the growth of facial hair. During puberty, males typically experience an increase in the thickness and distribution of facial hair, including the development of a beard and mustache. This is driven by the influence of androgens, such as testosterone.
2) Adam’s Apple:
Another secondary sexual characteristic that distinguishes males from females is the Adam’s apple. The Adam’s apple, or laryngeal prominence, is a noticeable protrusion in the throat area, specifically in the front of the larynx. It becomes more prominent during puberty in males due to the growth of the laryngeal cartilage, which is influenced by the increase in testosterone levels. Females also have a laryngeal prominence, but it is generally less prominent than in males.
When a concave mirror is placed facing Sunlight, the Sun’s rays or sun light converge to a point 10 cm from the mirror. Now, if you place 2 cm long candles flame 20 cm away on the principal axis of the mirror, where would you specify a place a screen to obtain the image of the candle? What would see the size of a image? Draw a ray diagram to justify your answer.
