Which of the following does not need to happen during a successful mitotic cell division? a)single-chromatid chromosomes must be segregated in full sets of the genome. b)of dna between homologous chromosomes must happen before metaphase. c)the chromatin must condense fully so that the chromosomes are compact. d)microtubules must be assembled as part of the spindle apparatus. e)each of the chromosomes must start mitosis containing two dna molecules

The correct answer is: B)of DNA between homologous chromosomes must happen before metaphase

Mitosis is a process of somatic cell division, whereby a single cell divides into two daughter cells that are genetically identical. There are five stages of mitosis:

1.Interphase- The cell grows and prepares for the division.DNA duplicates, two copies of chromosomes are formed

2.Prophase- duplicated chromosomes condense- become compacted and tightly wound. Mitotic spindle which  organize the chromosomes is formed. Chromosomes attach to microtubules.

3.Metaphase-Chromosomes are lined up along the equator of the elongated cell (metaphase plate is formed).

4.Anaphase- the sister chromatids are moving to opposite ends of the elongated cell.  

5.Telophase- chromatids are on the opposite ends and cell division is almost over.

The phase after these is cytokinesis where the cell's cytoplasm divides.

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
