Answer:
Explanation:
1) The simplest structure is cubic system like simple cubic, body-centered cubic and face-centered cubic in the crystal system.
2) Yes, all minerals have crystal structures because minerals have definite crystal structure. Minerals are solids that are formed naturally through the inorganic processes. Some mineral properties are density, shape, color and hardness.
3) Minerals are the naturally occuring inorganic substances which have ordered atomic arrangement, they are not made by humans that's why we can't predict the specific structure of majority of minerals.
Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.

Algae: any of numerous groups of chlorophyll-containing, mainly aquatic eukaryotic organisms ranging from microscopic single-celled forms to multicellular forms 100 feet (30 meters) or more long, distinguished from plants by the absence of true roots, stems, and leaves and by a lack of nonreproductive cells in the reproductive structures: classified into the six phyla Euglenophyta, Crysophyta, Pyrrophyta, Chlorophyta, Phaeophyta, and Rhodophyta.
Amboeda: any of a large genus (Amoeba) of naked rhizopod protozoans with lobed and never anastomosing pseudopodia, without permanent organelles or supporting structures, and of wide distribution in fresh and salt water and moist terrestrial environments
Asexual reproduction: reproduction (as cell division, spore formation, fission, or budding) without union of individuals or gametes
Cilia: minute short hairlike process often forming part of a fringe
Diatom: any of a class (Bacillariophyceae) of minute planktonic unicellular or colonial algae with silicified skeletons that form diatomaceous earth
