The energy used by sperm to move up the fallopian tube is stored in the epididymis <span>of the sperm's midpiece. </span>The epididymis<span> is a tube located at the back of the </span>testicles. During ejaculation, the sperm move from the lower part <span>of the </span>epididymis. They<span> have not been activated by products from the prostate gland yet, and they are not able </span>to swim. However, they are transported through the peristaltic action of muscle layers within the vas deferens. They are mixed with the diluting fluids of the seminal vesicles and other accessory glands before ejaculation.

Answer:
FALSE
Explanation:
because birds doesn't chew their food because they doesn't have teeth therefore the seed remains in one piece and they still can germinate.
<h3><u>Answer;</u></h3>
d. a neuron recharges before it can fire again.
<h3><u>Explanation;</u></h3>
- <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
- <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
- There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
- Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.
Blue is the correct answer
Peroxisomes play a key role in the oxidation of specific biomolecules. They also contribute to the biosynthesis of membrane lipids known as plasmalogens. In plant cells, peroxisomes carry out additional functions, including the recycling of carbon from phosphoglycolate during photorespiration.
