Azurite has the formula Cu 3 (CO 3) 2 (OH) 2, with the copper(II) cations linked to two different anions, carbonate and hydroxide. It is one of two relatively common basic copper(II) carbonate minerals, the other being bright green malachite. Aurichalcite is a rare basic carbonate of copper and zinc. [8]
Meiosis research within mammal populations is restricted due to the fundamental nature of meiosis. [2] In order to study mammalian meiosis, a culture technique that would allow for this process to be observed live under a microscope would need to be identified. [2] By viewing live mammalian meiosis, one can observe the behavior of mutant ...
During G 2, the cell undergoes the final stages of growth before it enters the M phase, where spindles are synthesized. The M phase can be either mitosis or meiosis depending on the type of cell. Germ cells, or gametes, undergo meiosis, while somatic cells will undergo mitosis. After the cell proceeds successfully through the M phase, it may ...
Azurmalachite is a mixture of azurite and malachite. [1] It is alternatively called azuromalachite, azurite-malachite and malachite-azurite. [2] Azurmalachite has a distinctive mottled green and blue coloration. It is relatively rare but can sometimes be found above copper deposits.

Azurite was frequently used in European Renaissance painting. It appears, for example, in the dark blue sky of a Spanish altarpiece painting by Bartolome Bermejo. [8] In this painting, azurite is also combined with lead white to paint the green robe of the Saint. [8] During this time, azurite was a common pigment used to paint a blue sky. [1]
Somatic cells compose the body of an organism and divide through mitosis. In contrast, gametes derive from meiosis within the germ cells of the germline and they fuse during sexual reproduction. Stem cells also can divide through mitosis, but are different from somatic in that they differentiate into diverse specialized cell types.
Meiosis generates genetic variation in the diploid cell, in part by the exchange of genetic information between the pairs of chromosomes after they align (recombination). Thus, on this view, [28] an advantage of meiosis is that it facilitates the generation of genomic diversity among progeny, allowing adaptation to adverse changes in the ...
