Answer:
Before cell division must occur, the chromosomes must replicate themselves. Sister chromatids are the two initially identical copies.
At least 40 percent of the world’s economy and 80 percent of the needs of the poor are derived from biological resources. In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.
Answer:
Action potentials can travel along axons at speeds of 0.1-100 m/s. This means that nerve impulses can get from one part of a body to another in a few milliseconds, which allows for fast responses to stimuli
Explanation:
Correct matches are:
1. pair of identical chromosomes (chromosomes that contain the same genes) from each parent, which all organisms produced by sexual reproduction receive -- Homologous pair
2. period between two periods of mitosis -- Interphase
3. the process involving the division of the nucleus in a reproductive cell; cell division in which the daughter cells have fewer chromosomes than the parent cell; responsible for genetic recombination -- Meiosis
4. the stage in the first meiotic division in which the homologous chromosomes line up as a pair, forming a tetrad of chromatids at the equator of the cell -- Metaphase 1
5. the stage in the second meiotic division in which the chromatid pair lines up at the equator of the cell -- Metaphase 2
