Explanation

Length is a base quantity in the International System of Units (SI), with the unit meter (m).

Volume and Area are derived quantities, calculated using base quantities like length.

Explanation

Aquatic arthropods like crabs, prawns, and some aquatic insects use gills to extract oxygen from water.

Gills provide a large surface area for gas exchange in an aquatic environment.

Explanation

Circinate vexation refers to the coiled arrangement of young leaves (usually in ferns) where the tip is rolled inward.

As the leaf matures, it gradually unrolls — a unique characteristic of fern leaves (fronds).

Explanation

Day-neutral plants like tomato flower regardless of day length (photoperiod).

They are not dependent on specific light or dark durations for flowering.

Explanation

Explanation

Each mesophyll cell in a leaf typically contains about 20 to 100 chloroplasts, depending on the plant species.

These chloroplasts are the site of photosynthesis, capturing sunlight to produce food.

Explanation

Explanation

A photometer measures the intensity of light absorbed or transmitted by pigments at different wavelengths.

It is used to study absorption spectra, especially in photosynthesis research.

Explanation

A glycosidic bond is a covalent bond that links two monosaccharides to form a disaccharide (e.g., glucose + fructose = sucrose).

This bond is formed through a condensation (dehydration) reaction, releasing a molecule of water.

Explanation

Cellular respiration is the process by which cells break down glucose to produce ATP (energy).

It occurs in mitochondria.

It provides energy for all cellular activities.
