Answer: Because two or more daughter cells will be formed, and each must have the parent chromosome in itself
Explanation:
Cell undergo cell division (mitosis or meiosis) as part of healthy development of a living organism. Before division, the cell during the resting phase( Interphase) makes two copies of all its organelles including nucleus, as it would form two daughter cells (in mitosis) or four daughter cells (in meiosis)
Epiglottis
The epiglotis is what allows you to swallow food without inhaling it. It acts as a gateway between the digestive and respiratory systems
Answer:
The average trait value changed in one direction.(In this case, larger size)
Explanation:
In evolution a natural selection can be disruptive, directional or stabilizing
In stabilizing no extreme trait is favored hence provides intermediate values .
Disruptive selection both extreme traits are favored over the intermediate trait.
Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.
In the case of swallow cliff mortality, selection favored the larger size.
