Answer: Polar substance, it dissolves polar substances, also called hydrophilic.

Explanation:

Water is a polar molecule and forms hydrogen bridges. Water is considered the universal solvent because it has great dissolving power. As water is a Polar substance, it dissolves polar substances, also called hydrophilic. Nonpolar substances, like oils, are hydrophobic and do not mix with water. The water is cohesive. Due to the formation of hydrogen bridges, water molecules attract strongly, keeping the substance stable. Also, water attracts other polar molecules, an association mechanism. That's why water wets polar materials like cotton and paper.

According to the general equation for conditional probability, if p (a^b')=1/6 and p(b')=7/12 , what is the value of p(a[b)?
Alex
P(B) = 1 - P(B') = 1 - (7/12) = 5/12 <span>P(A∩B)=<span><span>P(A∩<span>B′</span>)/</span><span>P(<span>B′</span>) </span></span>× <span><span>P(B)/</span>1

</span></span>Plugging values into the last equation we get: <span>P(A∩B)=<span><span>1×12×5 / </span><span>6×7×12 </span></span>= <span>542</span></span>
Now we can make use of the following formula <span>P(A|B)=<span><span>P(A∩B) / </span><span>P(B)</span></span></span><span> by plugging in the values that we have found.
</span>
<span>5/42 is the numerator and the denominator is 5/12.
</span>

The bottom (denominator) is P(B) which equals 5/12.

<span>P(A|B)=<span><span>5×12 / </span><span>42×5 = 6/210

6/210 = 2/7

</span></span></span><span>p(a[b]) = 2/7</span>

Answer:Transcriptional Regulation  

Explanation:

Eukaryotic gene expression can be regulated during the time of transcription and RNA processing, which takes place in the nucleus of the cell and then during the time of protein translation in the cytoplasm.

Further regulation is being carried during the time of post transnational modification. The conservation of energy is very important because it saves the overall energy and space in the body.

Hence, the most important point for the regulation would be transcriptional regulation.
