Answer:
Explanation:
During mitosis, the chromosomes are distributed equally in the resulting chromosome. The chromosome number was doubled in the S phase of the interphase and the cell is ready for mitosis. The chromosomes are more condensed and twisted in prophase. It is also double in length. During the metaphase, the chromosomes are arranged in the metaphase plate. The microtubules from the centriole attach to the centromere of each chromosome and pull them towards the pole.
Thus each chromatid pulls apart and migrates towards the poles. The nuclear membrane and nucleus disappear during mitosis. At the end of telophase, the daughter cells contain an equal number of chromatids as in the parent cell.
Sometimes the microtubules of centrioles do not function properly and fail to pull the chromosomes equally to the cells. Thus one of the daughter cells contains more chromosomes and another fewer chromosomes. This occurs in anaphase. This results in the non-disjunction of chromosomes.
Sometimes centromere splits transversely instead of longitudinal division. This results in the formation of 2 daughter chromosomes of unequal length. This is called the isochromosomes.
The number of chromosomes distributed in the daughter cells results in a normal cell or any genetic disorder. The main function of mitosis to produce daughter cells having an equal number of chromosomes present in the parent cell.
Answer:
The correct answer is true.
Explanation:
Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages: oral, pharyngeal, and esophageal stages
During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.
Thus, true is the correct answer.
Answer:
The ball may be hit above the net and the player's hand hitting the ball may pass to the opponent's side but WITHOUT touching the net.
On the other hand, underneath the net the ball cannot pass, nor can it go to the opponent's court, the bottom of the net is disabled for the game or ball pass.
Explanation:
In volleyball, the net must not be touched, the net must not be dropped and the ball must always pass over it in order for the score to be considered in the game, otherwise, if some of the situations are written, the players will be disqualified. points or they will not be considered
