The best description about the brain stem is: it is the most important organ of our body's survival. It connects the brain and the spinal cord, controls the vital organs like the lungs and heart and it also coordinates the many essential body reflexes.
Answer:
Prophase → Metaphase → Anaphase → Telophase (PMAT)
Explanation:
Meiosis II will have 
chromosomes.
Meiosis:
- Somatic cells divide during meiosis, a process in which the genetic makeup or quantity of chromosomes in the daughter cells is maintained.
- In sexually reproducing organisms, a kind of cell division known as meiosis results in a decrease in the number of chromosomes in gametes (the sex cells, or egg and sperm). Human body cells, also known as somatic cells, have two sets of chromosomes and are diploid (one from each parent).
- A single cell splits twice during the meiosis process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.

Answer:
H1
Explanation:
Histones H2A, H2B, H3 and H4 are known as the core histones which means that there are building nuclesome. H1 is known as the linker histone which binds to the "linker DNA" region between nucleosomes, helping stabilize the chromatin fiber. The linker histone H1 binds the nucleosome at the entry and exit sites of the DNA, thus locking the DNA into place and allowing the formation of higher order structure.
The cell wall protects a plant cell by giving it protection and support.
The cell wall is made of cellulose which is a specialized sugar that helps give the wall structure and support to protect the inner part of the cell.
