An earthquake is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's crust that creates seismic waves.
Anatomical structure, possible diet, and reproduction evidence.
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.
A) Crossing over is the mechanism of genetic variation that results from the exchange of gene segments between non-sister chomatids.
Linda’s belief in her capabilities is known as self-efficacy.
<u>Explanation:</u>
The concept of self efficacy was proposed for the first time by psychologist Albert Bandura. According to him self –efficacy means the ability of a person to execute courses of action that are required to deal with prospective situations. Self-efficacy determines the power of a person to face challenging situations and the choices he or she makes in life.
An individual’s external experiences and self perception are crucial in the development of self-efficacy. People with high self-efficacy tend to give a try in mastering even the hardest tasks rather than trying to avoid them.
