Explanation:
Cholesterol concentration = 27 mg/ 232 mL
Change unit mg/ml to kg/m³
1 kg = 1000 g
1 g = 1000 mg
1 kg = 1000000 mg
1 kg = 10⁶ mg
10⁶ mg = 1 kg
1 mg = 10^-6 kg
m³ = 1000 L
1 L = 1000 mL
m³ = 1000000 mL
m³ = 10⁶ mL
10⁶ mL = m³
1 mL = 10^-6 m³
Cholesterol concentration = 27 mg/ 232 mL
27 × 10^-6 kg/ 232 × 10^-6 m³
= 27/232 kg/m³
Germanium (Ge) is an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). As it has an atomic mass greater than that of sulfur (S), but less than that of cadmium (Cd).
<h3>Why does the element of the same group have similar chemical behavior?</h3>
The chemical behavior of elements depends on the number of valence electrons in their outermost shell. Elements placed in the same group have the same number of valence electrons. Therefore, elements placed in the same group of the periodic table have similar chemical properties.
The elements having a similar outer electronic configuration in their atoms are arranged in the same group of the periodic table. These valence electrons are responsible chemical properties and reactivities of the elements.
Therefore, silicon and lead can be replaced by any element belonging to the same group in which Si and Pb are present. So we have germanium and tin. But germanium is the element that has an atomic mass greater than sulfur (S), but less than cadmium (Cd).

I believe it is ni . Hope this helps
Answer:
The controlled variable of an experiment is the one thing that stays the same in an experiment.
Explanation:
An example would be : if I have two pennies, both dunked in water, but than I change one to be dunked in vinegar, the one dunked in water still is the constant or the controlled variable.
