The cell will enter the G1 phase. During this phase, proteins and nucleotides needed for DNA replication will be produced. Also,
kolbaska11 [484]

Answer and Explanation:

The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.

  • During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.

The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.

  • During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
  • G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.

6. Would there be a net flow of water in one direction in the following situations? Explain your answers.
amid [387]

Answer: There won't be a net flow of water in one direction in the situation.

Explanation: The concentration of NaCl inside the cell and its concentration outside the cell is the same. This means that there is equilibrium (a balance) between the inside environment of the cell and the outside environment of the cell. And because there is equilibrium between the two sides there will not be a net flow of water in one direction. The flow of water must be in opposite directions (inside and outside) so as to maintain a balance between the two environments.
