Answer:
The human cell cycle has two main phases: the interphase and the M phase
Explanation:
Just like every cell, the human cell cycle has two main phases which are;
- The interphase
- The M phase
The interphase phase is further divided into 4 respective sub-phases namely;
- phase which is essentially a resting/quiescence phase. It reserved for cells that have no need to divide unless they are called upon.
- phase, a phase where cell growth and development takes place.
- S phase, a phase where DNA is synthesized.
- phase, a phase where protein is synthesized.
The M phase is known as the active division phase. M can be mitosis or meiosis depending on the type of cells. Reproductive/sex cells will undergo meiosis while somatic/vegetative cells will undergo mitosis.
Mitosis is further divided into prophase, metaphase, anaphase and telophase while meiosis is divided into prophase I, metaphase I, anaphase I, telophase I and prophase II, metaphase II, anaphase II, telophase II respectively.
The answer for your question is D
Hi there,
Speed of sound in water is approximately 1500 meters per second (the exact speed depends on the depth of water and its density) and the speed of sound in air is approximately 340 meters per second. So sound is almost 4.4 times faster in water than in air. I hope this helped :)
