Answer:
Explanation:
Assume that a student is given two different models of bacteria, with one model consisting of big bacteria and the other consisting of small bacteria. How can the student demonstrate the theory of endosymbiosis using the models?
<h2>Clonal Selection to a Phosphorylation Cascade </h2>
Clonal selection describes the roles of compartments of the privileged operation in reply to specific antigens attacking the basis in immunology. A phosphorylation cascade is a series of situations wherever one catalyst phosphorylates is different. It makes a succession reactions driving the phosphorylation of thousands of proteins. This can be observed in omen transduction of hormone communications.
Answer:
The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.
Explanation:
The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.
A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
Placenta Previa
Placenta Previa is a disorder
that arises from the implantation and development of the placenta in the lower segment
of the uterine. The cause of this disorder is unknown. The three types of placenta
previa are complete, partial and marginal previa. The most common symptom of placenta
previa is painless bleeding during the third trimester.
