Answer:
<h2>
certain genes being expressed in some cells and not in others</h2>
Explanation:
The DNA is present in every cell of the multicellular organism but that does not mean that every cell will perform the same function.
The function of the cell is decided during the cell differentiation phase the function of the cell is determined by the expression of specific genes. Expression of these genes controls the functions of the cell.
In the given question the differences in the structure and function of the brain and kidney arise due to different expression of genes in different cells.
Thus, the selected option is the correct answer.
Administration of morphine (roxanol) brings relief from sever pain along with mild to moderate pain and this relief is the primary indication for Administration of morphine (roxanol). It is also used to relieve pain of cancer, postoperate, anxiety, and dypsnea , pain due to acute myocardial infarction. It is also used as a sedative before operations
Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.
Dwarf genotype frequency = 
= 25% = 0.25
Frequency of allele t = q = 
= 
= 0.5
According to the equation,
p + q = 1
p = 1 - 0.5 = 0.5
Now, the frequency of heterozygous tall plants would be-
2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
No, because of the mass amount of fossil fuels used during the Industrial Revolution.
The excess moisture ( water) in the food items boils up immediately and busts both shortening and water around.
<h3>Reaction between hot shortening and water</h3>
Shortening are known to be fats at room temperature and are usually used in the baking of cakes and bread.
When placed in the temperature that is high, it melts to become liquid.
When you pour a food item that contains excess moisture on hot shortening, the water comes in contact with a higher temperature than the shortening's boiling temperature, so the water starts boiling immediately, and busts both shortening and water around.
