Answer: The other ova become polar bodies.
Explanation: After meiosis I and II in oogenesis, there should be 4 eggs, but there aren't because the other eggs 3 eggs become these small cells called polar bodies that end up dying out through apoptosis. The reason why polar bodies are made is because they take out extra DNA that the single ovum is supposed to have.
So only 1 egg is made and the rest are polar bodies that get rid of extra DNA and then die by apoptosis.

When positive regulation occurs a transcription factor is required to bind at the promoter in order to enable RNA polymerase to start transcription.
RNA means ribonucleic acid and it is a long single-stranded chain of cells that processes protein.

The term myoparesis is used to describe the weakness or slight paralysis of the muscles. The myoparesis can begin in a person suddenly or it might progress with gradual weakness of the muscles. The affected individual may suffer from weakness of the muscles with incomplete paralysis along with experiencing pain and spasms in the affected muscles. The causes for the development of myoparesis includes stroke, cerebral palsy, multiple sclerosis, and spinal cord injury.
Hence, the answer is 'weakness or slight muscular paralysis'.
The answer is; decreasing
When a particular geographical region is exposed to the sun for some time, the atmosphere is heated and the air mass in the region become less dense as it warms up. This is how low-pressure occur in the world. Wind from the high-pressure system (with denser air masses) begins to blow towards the low-pressure regions to replace the rising air masses.
