The number of bones in a newborn baby is:
The correct answer is 300 because infants are born with a skeleton containing roughly 300 separate elements composed largely of flexible cartilage.
- Step 1 (Skeletal Development): A newborn infant has roughly 94 more bones than a fully grown adult. This flexible structural design is essential to allow the baby to fit safely through the birth canal and accommodate rapid infant growth.
- Step 2 (The Ossification Process): As the child develops through childhood, a biological process called ossification takes place. This causes separate soft cartilage segments to gradually fuse together into solid bone, lowering the total count to 206 by adulthood.
- Incorrect Options:
- 200 is incorrect because it falls below the standard adult skeletal baseline count of 206 bones.
- 250 is incorrect because it underrepresents the true separate bone segment configurations found at birth.
- None of these is incorrect because 300 is the widely accepted biomedical average benchmark.

The radius of a circle is 10 cm and the length of one of its chords is 12 cm then the distance of the chord from the center is:
The correct answer is 8 cm. This problem is a classic application of the perpendicular from the center to a chord theorem in circle geometry. According to this theorem, a perpendicular drawn from the center of a circle to any chord bisects that chord, meaning it divides the chord into two equal halves.
Step‑by‑Step Solution
- Step 1: Visualize the right triangle. Draw a circle with center O. Let AB be a chord of length 12 cm. Draw a perpendicular from O to AB, meeting AB at point M. Since OM ⟂ AB, M is the midpoint of AB.
- Step 2: Find the half‑chord length. AM = MB = 12 ÷ 2 = 6 cm.
- Step 3: Identify the hypotenuse. In right triangle OMA, OA is the radius of the circle, so OA = 10 cm (the hypotenuse).
- Step 4: Apply the Pythagorean theorem. OM² + AM² = OA² → OM² + 6² = 10² → OM² + 36 = 100 → OM² = 64 → OM = √64 = 8 cm.
Thus, the perpendicular distance from the center to the chord is 8 cm.
Why the Other Options Are Incorrect
- 6 cm (Option 1): This is the length of the half‑chord (AM), not the distance from the center. Many confuse the two values.
- 10 cm (Option 3): This is the radius of the circle. The radius is the hypotenuse, not the distance from the center to the chord (which must be shorter than the radius).
- 12 cm (Option 4): This is the total length of the chord itself. The distance from the center to the chord is always less than the radius for any non‑diameter chord, so 12 cm (greater than 10) is geometrically impossible.
Hence, applying the perpendicular‑bisector theorem and the Pythagorean theorem confirms that the distance is exactly 8 cm.

A matter can exist in which of the following forms:
The correct answer is All of these because solid, liquid, and gas represent the three classical states of matter commonly observed in nature.
- Step 1 (States of Matter): Matter is defined as anything that possesses mass and occupies physical space. Depending on the thermal energy and pressure applied to its atoms or molecules, it can easily change forms.
- Step 2 (The Classical Phases): A Solid has a fixed volume and shape; a Liquid maintains a fixed volume but conforms to the shape of its container; a Gas expands freely to fill both the volume and shape of its container. Therefore, all three are valid states.
- Incorrect Options:
- Liquid is incorrect on its own because it overlooks the fact that matter can also freeze into solids or vaporize into gaseous phases.
- Solid is incorrect on its own because it fails to represent the flowing liquid or dispersed gaseous states matter can acquire.
- Gas is incorrect on its own because it ignores the condensed phase states that substances manifest under standard conditions.
