Explanation

Spiral cleavage is characterized by diagonal cleavage planes that are not symmetrical between the poles, resulting in unequal blastomeres arranged in a spiral pattern.

Determinate cleavage means that the fate of each blastomere is predetermined early on, meaning each cell has a specific developmental role. 

Explanation

mRNA makes up only about 1–2% of the total DNA or genetic material content in a typical cell.

Most of the DNA is non-coding or used for other RNAs like tRNA and rRNA.

Explanation

Electric flux (Φ) is maximum when E and A are parallel, i.e., angle = 0°.

Formula: Φ = E·A·cosθ → cos(0°) = 1 gives maximum flux.

Explanation

The gravitational constant (G) is given by F = G * (m1 * m2) / r².

Unit of G = N * m² / (kg * kg) = Nm²kg⁻².

Explanation

Cluttered means گندا یا ناگوار ، اکثر چیزوں کے ساتھ آس پاس بکھر جاتا ہے

Littered means بکھرے ہوئے یا ناکارہ اشیاء سے بھرا ہوا ہے

Explanation

An infinite geometric series converges (has a finite sum) only if the absolute value of the common ratio, |r|, is less than 1. If |r| ≥ 1, the series diverges, meaning it does not approach a finite sum. 

Explanation

Curie (Ci) is a unit that measures the rate of radioactive decay.

1 Curie = 3.7 × 10¹⁰ disintegrations per second.

Explanation

The cell membrane is composed of roughly 40–50% lipids, primarily phospholipids and cholesterol.

These lipids form the bilayer structure, essential for membrane fluidity and barrier function.

Explanation

The sum of the first n odd numbers is given by:

1 + 3 + 5 + ... + (2n - 1) = n²
