The difference between Prokaryotic cell and Eukaryotic cell are;

\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or}    & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \  membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

Two consecutive even positive integers have a product of 2,400. What is the smaller of the two numbers?
Flura [38]

Answer: <u>Option C; 48</u>

Explanation:

Let one number = x

Other number = x+2

According to question-

[x] [x+2] = 2400

x^{2} + 2x - 2400 = 0

Solving this equation, we get-

[x - 48] [x - 50 ] = 0

x = 48 or 50

Since 48 is the smaller number here, answer is option C
