The poles cannot move 10 km a year because they are connected to earth which moves way more than that
The Accessory Nerve (XI) is the only cranial nerve that has fibers that enter and leave the skull through different foramina.
The Accessory Nerve (XI):
- Efferent nerves from the brainstem and spinal cord give rise to cranial nerve 11.
- They help to enable phonation and movements of the head and shoulders when they leave the skull through the jugular foramen.
- The accessory nerve is joined by sensory fibers from the cervical plexus, giving its target muscles general sensation.
- The accessory nerve divides into spinal and cranial portions.
What is a foramen?
- An opening that allows the movement of structures from one area to another is called a foramen (plural foramina).
- The term "cranial foramina" refers to the numerous foramina in the base of the skull that carry cranial nerves, blood vessels, and other structures.
- The largest cranial foramen is the foramen magnum.
- It is located in the posterior cranial fossa of the occipital bone and enables the medulla and meninges, vertebral arteries, anterior and posterior spinal arteries, and dural veins to pass through.
- Through the foramen magnum, the spinal division of the accessory nerve ascends to join the cranial division.
- The united nerve then leaves the body through the jugular foramen.
- The petrous portion of the temporal bone forms the jugular foramen anteriorly, while the occipital bone forms it posteriorly.
Thus, the Accessory Nerve (XI) enters through the foramen magnum and leaves through the jugular foramen.

Explanation:
The watermelon fruit when is covered by the molds, a type of fungus which can grow on the moistened substances. The molds can be characterized by their black, green and white spores.
The molds grow on the moistened surface by growing their hyphae which can form mycelium. These hyphae continuously produce enzymes which can breakdown the organic matter present in the watermelon.
Therefore, the matter and energy of the watermelon are transferred to the molds as it forms the next trophic level in the food chain.
Answer: The base pair rule for RNA is that adenine pairs with uracil, thymine pairs with adenine and cytosine pairs with guanine.
Explanation: RNA contains adenine, uracil, cytosine and guanine while DNA contains adenine, thymine, cytosine and guanine. Thymine is not found in RNA while uracil is not found in DNA. In RNA base pairing, Watson and Crick proposed a rule that wherever adenine is found in DNA, Uracil occurs in the complementary RNA strand, wherever thymine is found in the DNA strand, adenine is found in the complementary RNA strand and wherever guanine occurs in the DNA strand, cytosine is found in the complementary RNA strand.
Answer: It's body is bilaterally symmetrical
Explanation:
The option that is not considered essential in determining whether the putative new life form shows the properties of life is that its body is bilaterally symmetrical.
The fact that the creature has cells signifies that it has life, reaction towards touch is also another factor that shows its has life.
We should note that its body shape doesn't signify I it has life or not. Therefore, the answer is D.
