Answer:
The illustration represents the mitochondria of the cells.
Explanation:
The image shows the structure of a mitochondrion, whose shape is "ovoid", which contains two membranes, a folded inner and a smooth outer, observing invaginations (mitochondrial ridges). This article contains the enzymes for the Krebs cycle, oxidative phosphorylation being responsible for the energy generator for the maintenance of cellular activity.
It has to be intensive, which means it does not depend on the amount of the substance. Boiling point, melting point, and density are three intensive physical properties.
It’s called an isotope which is an atom with the same number of protons but a different number of neutrons
1. Answer:
1.0 × 10–9 M OH–
Explanation:
pH = -Log[H+]
pOH = -Log[OH-]
But;
pH + pOH = 14
Therefore;
[H+] + [OH-] = 1.0 × 10^-14 M
Therefore;
[OH-] = 1.0 × 10^-14 M - (1.0 × 10^–5 M)
= 1.0 × 10^-9 M OH–
2. Answer;
pH = 7.28
Explanation;
pH = -Log[H3O+]
Given;
[H3O+] = 5.2 × 10^–8 M
Therefore;
pH = - log [5.2 × 10^–8 M]
= 7.28
The pH is 7.28
