Naked seed plants are called _____?

Explanation
Gymnosperms are plants with "naked seeds, " meaning their seeds are not enclosed within a fruit. This group includes conifers like pine trees.

Explanation
Active transport moves molecules against the concentration gradient, which requires energy (ATP). Passive transport and facilitated (not vacillated) transport do not require energy.

Explanation
The word zoology comes from the Greek words " zoon " (meaning animal) and " logos " (meaning study). So, zoology means the study of animals in Greek origin.

Explanation
The cross product (A × B) is a vector whose magnitude is given by: | A × B | = |A||B| sinθ Its direction follows the right-hand rule .

Explanation
Work, mass and distance are scalar quantities because they have magnitude but no direction, but they are not vector quantities. Vector Quantities : Velocity, momentum, torque, acceleration, weight, displacement. Scalar Quantities : Work, distance, speed, mass.

Explanation
The cross product of two vectors A × B ≠ B × A; in fact, A × B = –(B × A), so it is not commutative. However, it does obey the distributive law over addition, and associative law applies with scalar multiplication but not for three vector cross products.

Explanation
Nitrogen gas (N₂) has a triple covalent bond between the two nitrogen atoms. This triple bond makes N₂ very stable and unreactive under normal conditions.

Explanation
Gas : No definite shape or volume – Expands to fill any container . Example: Oxygen, CO₂. Solid : Fixed shape and volume (e.g., iron). Liquid : Fixed volume, no fixed shape (e.g., water).

Explanation
The atomic mass of sodium (Na) is approximately 23 atomic mass units (amu). It is based on the sum of protons and neutrons in its most common isotope.

Explanation
Sum = 4 + 5 + 6 + 8 + 12 = 35 Average = 35 ÷ 5 = 7
