What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.
<h3>Concept conveyor belt </h3>
The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.
As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.
Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is It becomes less dense and rises to the surface.

Answer:
<u>C. Broca's Area</u>
Explanation:
Broca’s area is located in the front part of the left hemisphere of your brain. It has an important role in turning your ideas and thoughts into actual spoken words. Broca’s area is the most active Source right before you speak.
Broca’s area also helps to pass the information to another part of your brain called the motor cortex, which controls the movements of your mouth. It’s named after a French doctor, Pierre Paul Broca, who discovered the region of the brain in 1861.

Answer: Options A, B, C and D are correct.
Explanation: They can trigger the activity of histone acetyltransferases.
These RNAs functions by binding to histone-modifying complexes, to DNA binding proteins (including transcription factors), and even to RNA polymerase II.
They can silence genes by promoting the formation of euchromatin by arranging hetero- or euchromatic regions into close proximity may stabilize these domains or it may control the spreading of post-translational modifications (PTMs) to nearest chromatin.
They are actively involved in X chromosome inactivation.
They can regulate the translation and stability of mRNAs.
In Eukaryotic cells RNA transcription is a closely regulated process. Transcription of a lncRNA may regulate the transcription of nearby mRNA genes, either positively (maintaining active chromatin structure) or negatively (for example, colliding polymerases). In these cases, the RNA product may have no importance at all, or it could have an additional function.
