For this item, we can notice that the first sequence is exactly identical to the second sequence. With this information, we can therefore assume that no alteration has been made to the protein.</span><span>
ANSWER: NO Alteration in Protein
2) </span><span>ATTGAGACCGT → GAGACCAGT
Since I do not know the bolded letters, I am not sure whether the region that was lost in the second sequence (ATT) is a noncoding region. Nevertheless, we can see that the second sequence is missing another A aside from the three initial letters.
ANSWER: Chance of Alteration in Protein
3) </span><span>TATAATATTA → TATATATTA
Like the previous item, an A is also missing in the second sequence for this item. The missing A comes in between the second and third T. Without the bolded letters, I cannot be sure whether this missing A is a noncoding region or not, but anyway this still indicates a chance of alteration in protein.
</span>ANSWER: Chance of Alteration in Protein
4) <span>ATTCATCTGG → ATTCATCGTGG
There is also one missing letter in this item like the previous two items. This time, it is the letter G that's supposed to be in between the rightmost C and T. Not knowing the bolded letters, we can still say that this missing G is a chance of alteration in protein.
</span>ANSWER: Chance of Alteration in Protein <span> 5) </span><span>TACCTACT → TACCTACT
</span>In this item, we can notice that the first sequence is exactly identical to the second sequence, just like the one in the first item. With this, we can therefore assume that no alteration has been made to the protein.
ANSWER: NO Alteration in Protein
6) <span>GATCTTACTT → GATCTTACTT
We can also notice in this item that the second sequence is still the same as the first sequence. Thus, this information will tell us exactly what we have concluded for items #1 and #5. Having no change in the sequence would definitely mean that the protein is not altered.
You have a pretty good shot at guessing this, because the earthworm has very little going on at the posterior end except the anus. And you probably saw this in lab, too.
I've attached a picture of the earthworm anatomy. Worms can't smell in the strictest sense, but they can use their receptors as kind of a combo smell-taste thing, and those are located in the anterior end.
The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.
The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
