If vector is less than 90° and greater than 0°, it’s positive. if it’s less than 180 and greater than 90, it’s negative. if there is no acceleration vector, it’s called zero acceleration.
Answer:
Firstly, many statistics are taken from a small group of people used to represent the general population. Say a news channel reported that 81% of teenagers in America were planning on going to a four-year college. This statistic is most likely taken from a randomly selected group of teenagers, and calculated with a margin of error. Because after all, it's nearly impossible to survey every single teenager in America. This can lead to some statistics that are not really representative of the actual percentage of people. This only gets more likely the larger the general population being "surveyed" is. Another reason is that the media is not always truthful with statistics. Things can be altered and not many people will notice. Hope this helps!
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.
