Which equation, in which k is a constant, represents an inverse proportion between the variables? V = T/k F = –kx2 PV = k y = kx
Alona [7]

The inverse proportion is PV = k

We can write the equation as <em>P</em> = k/<em>V</em> or <em>P</em> ∝ 1/<em>V</em>. Thus, <em>P</em> and <em>V</em> are <em>inversely related</em>.

We can rewrite <em>V</em>= T/k as <em>V</em> = k<em>T</em> or <em>V</em> ∝ <em>T</em>. Thus,<em> V</em> is <em>directly proportiona</em>l to <em>T</em> .

<em>F</em> = -k<em>x</em>² is <em>neither a direct nor an invers</em>e relation.

<em>y</em> = k<em>x</em> – 8 is a linear relation, but it is <em>not a direct proportion</em> because of the “-8” term.

Which type of cell can have a flagellum or cilia
Y_Kistochka [10]

Answer:

Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts. Cilia and flagella are formed from specialized groupings of microtubules called basal bodies.
