Explanation

• When light is focused in front of the retina, it creates a blurred image, indicating nearsightedness (myopia).
• This occurs because the eyeball is too long or the cornea is too steep.
• It causing light to focus before reaching the retina.

Explanation

• Measuring cylinders are designed to measure the volume of liquids.
• It allowing for precise measurements in scientific experiments and procedures.

Explanation

• Human growth hormone (HGH) is used to treat growth hormone deficiency, which can cause dwarfism or short stature.
• HGH replacement therapy can help promote growth and development in children and adolescents with growth hormone deficiency.

Explanation

A converging lens (also known as a convex lens) refracts parallel rays of light and converges them at a single point, called the focal point.

Explanation

• Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes and tamarinds.
• It also found in bananas, avocados, and citrus fruits.

Explanation

• The given reaction, CaO + CO2 → CaCO2, is an example of a Combination Reaction, also known as a Synthesis Reaction or Addition Reaction.
• In this reaction, two substances, calcium oxide (CaO) and carbon dioxide (CO2), combine to form a single compound, calcium carbonate (CaCO2).

Explanation

MMR vaccines are given to children to develop resistance against:

• Measles
• Mumps
• Rubella (German measles)

Explanation

• During Prophase, the chromatin condenses and becomes visible as chromosomes.
• This is the stage where the chromatin becomes thickened, shortened, and organized into visible chromosomes.

Explanation

• Violet light has the smallest wavelength, approximately 380-450 nanometers (nm).
• While red light has the longest wavelength, approximately 620-750 nanometers (nm).
• The order of colors in the spectrum, from longest to shortest wavelength, is: Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV).

Explanation

A refracting telescope has two lenses:

1. A primary lens (objective) that collects and focuses light.
2. A secondary lens (eyepiece) that magnifies the focused light to form an image.
