Answer:
Bacillus anthracis, the causative agent of the human disease anthrax, Bacillus cereus, a food-borne pathogen capable of causing human illness, and Bacillus thuringiensis, a well-characterized insecticidal toxin producer, all cluster together within a very tight clade (B. cereus group) phylogenetically and are indistinguishable from one another via 16S rDNA sequence analysis. As new pathogens are continually emerging, it is imperative to devise a system capable of rapidly and accurately differentiating closely related, yet phenotypically distinct species. Although the gyrB gene has proven useful in discriminating closely related species, its sequence analysis has not yet been validated by DNA:DNA hybridization, the taxonomically accepted "gold standard". We phylogenetically characterized the gyrB sequences of various species and serotypes encompassed in the "B. cereus group," including lab strains and environmental isolates. Results were compared to those obtained from analyses of phenotypic characteristics, 16S rDNA sequence, DNA:DNA hybridization, and virulence factors. The gyrB gene proved more highly differential than 16S, while, at the same time, as analytical as costly and laborious DNA:DNA hybridization techniques in differentiating species within the B. cereus group.
Explanation:
Answer:
The correct answer would be - hypotonic solution.
Explanation:
The egg cell contains more solute than the sucrose solution which makes the sucrose solution a hypotonic or low solute solution. Hypotonic solution is a solution that has low concentration of the solutes than the another solution. This tye of case leads to the movement of the water to, move in the area of high concentration of solutes.
In this case the water will move in to the egg and swell the egg due to the diffusion of water through semipermeable membrane from low solute area to high solute area.
Yes it's a protein called Hemoglobin in the red blood cells and it carries oxygen around your body and to your lungs, so it is TRUE.

B, an Amoeba. Amoebas are a great example of a unicellular organism, and they rely on a surface area to volume ration which allows them to grow and eat.
The nucleus, helps identify if the cell is eukaryotic or prokaryotic.
I don’t really understand the question.
