Answer:
Unicellular organisms achieve locomotion using cilia and flagella. By creating currents in the surrounding environment, cilia and flagella can move the cell in one direction or another.
Explanation:
In addition to content, elements also support attributes <span>that specify the use, the behavior, and in some cases the appearance of an element.
The other options just do not fit the blank in this question, which is why the word <em>attributes </em>is the correct one to choose here.</span>
I think carbon monoxide and sodium chloride are the organic compounds.
I hope this helps :-)
Analyze the Name of complex Compound.
T<span>etracarbonylplatinum(iv) chloride
So, there are,
4 Carbonyl groups = 4 CO = (CO)</span>₄
1 Platinum Metal = 1 Pt = Pt
Unknown Chloride atoms = ?
In complexes positive part is always named first, so the sphere containing Pt and carbonyl ligands is written first,
[Pt (CO)₄]
The charge on sphere is +4 because CO ligand is neutral, and Pt has a Oxidation state of four as written in name (IV),
So,
[Pt (CO)₄]⁴⁺
Now, in order to neutralize +4 charge we should add 4 Chloride ions, So,
[Pt (CO)₄] Cl₄
Answer : The molarity of the ion is 
Explanation : Given,
Density of sample = 1.00 g/mL
Concentration of
= 42 mg/kg
First we have to calculate the volume of sample.
Let us assume that the mass of sample be 1 kg or 1000 g.



(1 L = 1000 mL)
Now we have to calculate the moles of 
As we are given that,
Mass of
in 1 kg of sample = 42 mg = 0.042 g
Molar mass of Ca = 40 g/mole

Now we have to calculate the molarity of the ion.


Therefore, the molarity of the ion is
