The right option is; A. Compounds can be separated by physical methods.

Compounds can be separated by physical methods is the statement about compounds that is false.  

A compound is a molecule that is formed from the combination of two or more different chemical elements. The atoms of the different elements that form a compound are held together by chemical bonds (covalent and ionic) that are not easy to break. The component of a compound can only be separated by chemical means and not by physical methods. An example of a compound is water (H2O) which is composed of hydrogen (H) and oxygen (O) atoms.

tensa zangetsu [6.8K]

Answer:

21 minutes or 0.35 hours

Explanation:

The formula for exponential population growth is

A = A_0* e^{kt}\\

where

A_0 = initial population of E.coli i.e 100

k is the rate of population growth i.e 2 as the population doubles

t is the time period i.e 20 minutes

Substituting the given values in above equation, we get -

A = 100 * e^{2 * \frac{20}{60} }\\\\A = 195

Generation time

G = \frac{t}{3.3 * log \frac{194}{100} } \\G = \frac{t}{0.949} \\G= 21 minutes

or 0.35 hours

Answer:

miR-223 inhibits the expression of the fibroblast growth factor (bFGF) gene, and thereby ESCs cells maintain their undifferentiated state .

Explanation:

Non-coding RNA (ncRNAs) are molecules that regulate gene expression, thereby playing important biological functions in cell differentiation, cell cycle, apoptosis, etc. MicroRNAs (miRNAs) are a type of ncRNAs capable of controlling gene expression patterns by regulating mRNA stability and by suppressing their translation into proteins. It has been shown that miRNAs function by imperfectly base-pairing with the 3′ UTR of target mRNAs (Pillai et al. 2005).
