<span>It would depend on the method of decolorization. The most common one is by using Acetone-alcohol. When your slide are decolorized too much with Acetone-alcohol, cells will appear to be pink since the crystal violet are washed out.</span>
In guinea pigs, rough coat (R) is dominant over smooth coat (r). Predict the genotypes and phenotypes of the offspring and give the genotypic and phenotypic ratios is a homozygous dominant guinea pig is crossed with a heterozygous guinea pig. 3. ... In humans, brown eyes (B) are dominant over blue (b).
I am pretty sure that it is D
With decomposition, the final deposition of particles(sediments) usually occurs at the mouth of a stream. Then a process called horizontal sorting occurs where the sediments that were once carried down are arranged from big to small. Decomposition in streams takes time so the speed of the water and wind should not affect it nor should gravity or the direction. Streams cannot change direction either unless human involement occurs
Hope this helps :)
Answer: Option E) polar
Amino acid-derived and peptide hormones are unable to diffuse across a cell membrane because they are polar
Explanation:
Amino acid-derived and peptide hormones such as serotonin, epinephrine, dopamine etc, are unable to diffuse across a cell membrane because they consist of several repeating units of amino acids with positively charged or negatively charged side chains.
Thus, the side chains make these hormones water-loving (hydrophilic), and impassable to the hydrophobic layer of the cell membrane.
