Hello there!
If a change in the body causes more change in the same direction the system is called positive feedback.
Answer:
d. hairpin
Explanation:
A double-stranded base-paired structure formed by folding a single strand of DNA or RNA back upon itself like a hairpin. Base pairs are the unit of nitrogenous bases which are joined together by hydrogen bonds. They synthesize the double helix model which contribute the folded structure of both RNA and DNA. Sugar and phosphate is the backbone of DNA. DNA has four nitrogenous bases named adenine, thymine, guanine, and cytosine.
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
