Compare and contrast the structure and function of a compound light microscope and a dissecting microscope.

1. both are electron microscopes, but the dissecting microscope has a higher magnification than the compound light microscope.

2. both are electron microscopes, but the compound light microscope can view only nonliving things.

3. both are light microscopes, but the compound light microscope has a higher magnification than the dissecting microscope.

4. both are light microscopes, but the dissecting microscope can view only nonliving things.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

not sure if this is what you'r looking for eubacteria and archaebacteria

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.
