Answer:
6 pairs of chromosomes
Explanation:
The cell cycle consist of 4 phases:
G1 Phase
S Phase
G2 Phase
M Phase
G1 Phase
In the G Phase cell duplicates its organelles. In the example the cell has 6 pairs of chromosomes. In every pair of chromosomes one chromosome comes from the father and one chromosome comes from the mother. Although these chromosomes carry similar genetic information there are some differences between them.
S Phase
In the S Phase each chromosome is duplicated
In the example the cell has 12 pairs of chromosomes. Since each chromosome has a identical copy, they are called sister chromatids.
G2 Phase
In G2 phase cell prepares for mitosis. In the example the cell has 12 pairs of chromosomes.
M Phase
The M phase in the Meiosis is divided in Meiosis 1 and Meiosis 2
In Meiosis 1 pairs of sister chromatids align and undergo homologous recombination. For chromosome 1 , 2 pairs of sister chromatids align and mix their genetic content. In the example the cell has 12 pairs of chromosomes. At the end meiosis 1, 6 pairs of chromosomes goes to one side of the cell and the other 6 pairs of chromosomes go to opposite side of the cell. Finally the cell divides and two cells are formed, each cell has 6 chromosomes.
At the metaphase 2 Meiosis each pairs of homlogous chomosomes is aligned al the center of the cell. In the example you have 6 pairs of chromosomes in each cell aligned at the center.
Answer:
It is a good idea to consider supply and demand when considering your future career. This will give us an idea of how easy or difficult it is to enter the area and make a living from it.
Explanation:
The ribbon is a set of toolbars at the top of the window in Office programs designed to help you quickly find the commands that you need to complete a task. Sometimes the ribbon can get hidden and it's hard to find. The quickest way to show the ribbon is to click on any visible tab, like Home<span>, </span>Insert<span> or </span>Design<span>. You might also want to hide the ribbon to maximize screen space.</span>
Answer:
1: Don't repeat yourself (DRY).
2: Keep it simple (KISS)
3. Minimize Coupling
4. Maximize Cohesion
5. Hide Implementation Details
6. Law of Demeter
7: Open/Closed Principle
Explanation:
1. Avoiding repetition is probably the single most fundamental tenet in programming.
2. Simplicity should always be a key goal. Simple code takes less time to write, has fewer bugs, and is easier to modify.
3. Any section of code (code block, function, class, etc.) should minimize the dependencies on other areas of code. This is achieved by using shared variables as little as possible.
4. Code that has similar functionality should be found within the same component.
5. Hiding implementation details allows change to the implementation of a code component while minimally affecting any other modules that use the component.
6. Code components should only communicate with their direct relations (e.g. classes that they inherit from, objects that they contain, objects passed by argument, etc.)
7. Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification. In other words, it is not recommended to write classes that people can modify, write classes that people can extend.
I hope this helps and I'm sorry if it doesn't.
Have a great day! :)
