Earth<span> can be divided into three main </span>layers<span>: the core, the mantle and the crust
Your answer would be, Core.
(Could also be called inner core)
Think of it as a watermelon, you have the crust, which is the green part, the mantle which is the whitish green part and the red which is the core.
Hope this helps.
In case you didn't get any of that, the answer is Core</span>
MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
- At the end of stage G1 and before S.
- Before anaphase in mitosis.
- DNA damage checkpoints in G1, S or G2.
The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

In general, a balanced diet contains relatively even amounts of carbohydrates, proteins, and lipids. Too much sugar (monosaccharides and other simple sugars) is unhealthy. Fruits and vegetables are importante sources of vitamins and minerals.
<h3>Do you consider your diet balanced and healthy? Why or why not?</h3>
I consider that the diet I follow is a balanced diet since I include in it greater amounts of healthy foods such as rice, beans, meats, fruits and vegetables than processed foods. My diet is focused on feeling good and this means that the meals I eat are healthy and make me feel good.
All of this is accompanied by <em>daily exercise, good sleep and consumption of multivitamins</em> to feel good and carry out my daily tasks in the best way.
Therefore, we can confirm that following a diet like the one narrated is a good way to have a balanced diet and a healthy way of life.
