10)since its by 6 its 12*6=72 is your answer.
12)4 cause 4*4=16 and 7*4=28.
Meiosis
Explanation:
The process in maple trees that decreases the chromosome number in the pollen cells from 52 to 26 is called meiosis.
Meiosis is an important cell division process in which diploid cells are turned into their haploid number.
- In meiosis the cells divides into half and produces four daughter cells from the diploid 2n cells.
- The cell divides twice here. It is common in all sexually reproducing cells.
- It also occurs in all single celled organisms that reproduces sexually.

The correct answer is: E) provide the defense for the CNS
Astrocytes are star-shaped cells found in central nervous system (brain and spinal cord) .Some of their functions include:
• Support of neurons by supporting endothelilal cell of blood–brain barrier,
• Provide nutrients to neurons
• Maintain ion balance and thus controlchemical environment around neurons
• Repair of injuries in the brain
• the secretion or absorption of neural transmitters…
The cells that provide the defense for the CNS are called microglia. Those cells are also glial cells, derived from macrophages and thus, part of active immune defense.
