In angiosperms, flowers are adaptations for reproduction. which of the following does not usually describe flowers that are pollinated by animals? a. they are tiny. b. they pollinate more efficiently than wind-pollinated plants. c. they produce nectar to attract pollinators. d. they are brightly colored

Ans. (A). They are tiny.

Angiosperms are seed-producing, flowering plants. The flowers are adaptive structures that help in reproduction. The flowers attract pollinators (animals, birds, or insects) that transfer the pollen grains from anther (male organ) to stigma (female organ).

Flowers, which get pollinated by animals or birds are bright in color, produce nectar and scent to attract pollinators. These flowers are generally larger in size. Pollination by animals is more efficient than wild pollination as many pollen get wasted during wind pollination.

Thus, the correct answer is option (A).

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
