No machine can achieve 100% efficiency in terms of work output. In any mechanical system, what is considered the most common cau
Alex777 [14]
The answer is A, friction.

Friction is the force that resists movement, and that's why oil is used as a lubricant and why ball bearings are used for machines that need to move with very little friction(i.e. bike wheels, roller skates, fidget spinners)

Answer B is too vague
C will probably reduce efficiency greatly, but not specifically in a way that turns work into thermal energy.
D is the same as C, except that it places the blame on the person using the machine, not the machine itself.


Hope I helped clear it up for you :)

1. Bees, flies, wasps, butterflies, and moths are significant insect pollinators. Moths are drawn to white flowers that are open at night, but bees and butterflies are drawn to brilliantly colored blooms with powerful scents that are open during the day.

<h3>What is pollination?</h3>

The act of moving pollen grains from an anther to a flower's stigma is called pollination. Flowers that are pollinated by insects typically generate a sweet nectar that the insects visit to consume. If a flower is self-pollinating, fertilization occurs when pollen stock from an insect contacts the stigma of the bloom. If the bug is bisexual, it will fly to another bloom and disperse the pollen.

2. Most flowers advertise themselves by being brightly colored and perched on long stems so they wave in the air and are closer to where insects are flying, as opposed to on the ground, where they would otherwise be. A flower's petal sizes and shapes, in addition to color, can draw insects.

3. Flowers draw insects because of their aroma or vibrantly colored petals. Nectar is a delicious liquid that many flowers generate that is consumed by insects. The female part of the flower is the carpel.

Answer 2. Flowers that are pollinated by insects have characteristics that enable insects, birds, or other animals to pollinate them while consuming the nectar. When an insect brushes by the stigma of a flower, whether it is the same bloom or another, pollen grains will adhere to the insect's outer layer and stick to the flower's stigma, pollinating the flower. When the two seˣ cells combine, fertilization occurs, the ovule develops into a seed, and the ovary becomes a fruit. The pollen grain then grows a pollen tube down the style to reach the ovary, which contains the ovules.
