Answer the following question given this paragraph: Prophase is the first and longest phase of mitosis, see Figure below . During prophase, the chromatin (DNA) coils up into visible chromosomes, each made up of two sister chromatids held together by the centromere. Also during this phase, the nucleolus disappears, and the spindle begins to form from the centrioles. Most eukaryotic cells contain structures known as centrosomes, consisting of a pair of centrioles. During prophase, the centrioles begin to move to opposite ends, or poles, of the cell. As the centrioles migrate, the fiber-like spindle begins to elongate between the centrioles. The spindle is a thin, cage-like structure made out of microtubules. In plant cells, the spindle forms without centrioles. The spindle plays an essential role moving chromosomes and in the separation of sister chromatids. Q: What is the first and longest phase of mitosis known as? Choices: - metaphase - telophase - anaphase - prophase A:
prophase

Answer the following question given this paragraph: The peripheral nervous system (PNS) consists of all the nervous tissue that lies outside the central nervous system. It is shown in yellow in Figure below . It is connected to the central nervous system by nerves. A nerve is a cable-like bundle of axons. Some nerves are very long. The longest human nerve is the sciatic nerve. It runs from the spinal cord in the lower back down the left leg all the way to the toes of the left foot. Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. Q: Which nervous system consists of all the nervous tissue that lies outside the central nervous system? Choices: - auxiliary nervous system - significant nervous system - function nervous system - peripheral nervous system A:
**Answer**
peripheral nervous system
Q: Answer the following question given this paragraph: Translation is the process of ordering the amino acids in the assembly of a protein. The word ribosome comes from ribo nucleic acid and the Greek soma (meaning body). Two Nobel Prizes have been awarded for work relating to the ribosome. The 1974 Nobel Prize in Physiology or Medicine was awarded to Albert Claude, Christian de Duve and George Emil Palade for the discovery of the ribosome, and the 2009 Nobel Prize in Chemistry was awarded to Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for discovering the detailed structure and mechanism of the ribosome. Q: Translation is the process of ordering the amino acids in the assembly of a? Choices: - carbohydrate - vitamin - lipid - protein A:
A: protein
