Sorry, I don’t remember much about Biology but if you need to talk I’m here everything will be okay, just be patient with yourself
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.
Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.
Explanation:
Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)
Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>
After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
It should be an igneous rock because it formed by the volcanoes lava cooling down
