Answer:
Allopatric speciation occur due to various environmental factors with in the environment.
Explanation:
Speciation occur when two population become so genetically different and the can not interbred to produce fertile off spring. The allopatric speciation occur when population become sepret and diverge over time due to natural selection,genetic drift,and mutation.Genetic drift is the sudden loss of gene from a population which cause the population evolvation. Mutation is also change in the genetic makeup of an individual.Natural selection is the phenomena selected by nature and natural forces are involve to select the trait in a living organism.
Answer:
B) stain only the thicker peptidoglycan cell walls
Explanation:
Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.
He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.
Thus, Option-B is correct.
Hydramacin-1 is potently active against Gram-positive bacteria activated but in case of gram negative bacteria it is not.
Gram-advantageous cocci encompass Staphylococcus catalase-high quality, which grows clusters, and Streptococcus, which grows in chains. The staphylococci similarly subdivide into coagulase-high quality S. aureus and coagulase-poor epidermidis and S.
Gram-fine micro organism motive fantastic issues and are the focus of many eradication efforts, but meanwhile, Gram-negative micro organism have been developing risky resistance and are therefore labeled by the CDC as a more severe chance.
Micro organism singular bacterium, common noun micro organism) are ubiquitous, in the main loose-living organisms regularly consisting of one biological mobile. They constitute a massive domain of prokaryotic microorganisms. generally a few micrometers in length, micro organism were a few of the first existence bureaucracy to seem on the earth, and are found in most of its habitats.
