During meiosis, segments of nonsister chromatids can trade places. this recombination of maternal and paternal genetic material is a key feature of meiosis. during what phase of meiosis does recombination occur?

This happens during prophase I.
Meiosis is the process of cell division which results in the formation of four haploid cells. These haploid cells, called gametes, have only half the number of chromosomes of the parent cell. Meiosis has two major phases; meiosis I and II. Meiosis I is separated into prophase I, metaphase I, anaphase I and telophase I. During prophase I, chromosomes are aligned and paired up. However, in this phase, chromosomes tend to trade and exchange part of their DNA. This recombination is also called crossing over.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
