A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a
copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell? The cell is ready to undergo mitosis, and a chemical signal will send the cell to prophase. The cell is undergoing meiosis and will cross over the genetic material next. The cell is in the S phase of interphase and will move next to the G2 phase. The cell is in the G2 phase of interphase and is ready to begin dividing.
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.
35-He had a slight weight increase because he was consuming more calories then he was burning. 36- The student can eat healthier things with less calories or exercise more to burn off the excess calories.
Sleep is an example. Circadian rythms are biological processes that repeats itself within a certain time frame, as sleep repeats itself approximately once every day.
Sense of smell is known to
be part of the chemosensory system or chemical senses. It also a warning
system that alert to danger signals such as fire, gas leakage or spoiled food.
Thus, the sense of smell comes from the specialized sensory cells known as
olfactory sensory neurons.
