Answer:
n+1; n+1; n-1; n-1
Explanation:
Separation of homologous chromosomes during anaphase I result in a reduction of the chromosome number to half in the daughter cells of meiosis. If two homologous chromosomes of a pair fail to separate from each other, they both will move to the same pole. In this case, one daughter cell of meiosis I will have both the homologous chromosomes of a pair (n+1) while the other one will lack it (n-1). Meiosis II in these two daughter cells will form a total of four cells. Two of the daughter cells will have one extra chromosome (n+1) while the rest two will lack one chromosome from the haploid set (n-1).
Answer:
All aspects of life, making proteins and chromosomes.
Answer:
Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should.
For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body.
Models show noticeable patterns, develop representations and explain scientific events.
