Bacteria have been the very first organisms to live on earth in the waters of the first oceans. At first, there were only anaerobic heterotrophic bacteria.
Answer:
Cytokinesis
Explanation:
After meiosis I finishes, the cell splits in a period called cytokinesis. Each cell then has half the original number of chromosomes.
Nuclear magnetic resonance provide information on the structure of a purified protein based on its nuclear spin properties in a magnetic field, whereas X-Ray crystallography uses diffraction pattern of protein in solid phase.
Explanation:
Nuclear magnetic resonance is a spectroscopic technique that involves change in nuclear spin energy in presence of an external magnetic field. It is based on the absorption of electromagnetic radiation in the radio-frequency region.
X-Ray crystallography is a method of determining the arrangement of atoms within a crystal.This technique is based the fact that when a beam of X-ray strikes a crystal, the beam gets diffracted. From the angle and intensities of diffraction a three-dimensional structure of electron density can be determined .
Answer: So basically we have to know does the material's characteristics/compositions affect its density?
Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.
The causative agent of gonorrhea and one of the causative agents of meningitis is part of Diplococci subgroup of proteobacteria.
Diplococci
In essence, diplococci bacteria are paired, spherical, or rounded bacteria. Some bacteria may appear ovoid (elongated) or bean-shaped, unlike staphylococci bacteria, which form grape-like clusters and are genuinely round.
Numerous infections in humans can be brought on by both Gram-positive and Gram-negative bacteria. The shape of diplococci bacteria can be spherical or elongated, as was previously mentioned. Therefore, some species—such as those of the staphylococci bacteria—might not be perfectly round. Because of this, they are frequently referred to as having an ovococcoid shape. Several studies have suggested that this form is the result of two different peptidoglycan machineries. The cell division machinery is in charge of producing septal peptidoglycan, which leads to the formation of the cell wall, in coccoids (really round bacteria), such as Staphylococcus aureus and Micrococcus.
