Answer:

Long tail and narrow head.

Explanation:

A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.

Vaselesa [24]

The statement that organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to their offspring is false. Organisms pass their traits and adaptation abilities to their offspring. These organisms have also characteristics that are advantageous for reproduction in a specific environment and leave more offspring in the next generation. The process is called natural selection.
