Answer:

Let's pick six liquids randomly, i.e. honey, corn syrup, whole milk, water, vegetable oil, rubbing alcohol, and put them in a beaker. The higher density liquid will take the bottom position whereas lower density liquids will be on above of high density liquids.

We know that honey has density (g/cm3) of 1.42, dish soap has 1.06, corn syrup has 1.33, milk has 1.03, water has 1.00 (standard), and vegetable oil and 0.92. Therefore, honey will be at the bottom most position (rank #1). Above which would be corn syrup (rank #2), dish soap (rank #3), milk (rank #4), water  (rank #5) and vegetable oil (rank #6).

The results might be surprising for some students who think that water has highest density.

True or false: <br><br> Mollusks are more closely related to roundworms than to annelids.
erik [133]

Answer:

False

Explanation:

Annelids are actually more closely related to species within the mollusk phylum than they are to their worm cousins in the flatworm and roundworm phyla. Although they look quite different on the outside, mollusks and annelids share a more recent common ancestor than roundworms and annelids.

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.

<span>Since there is usually more than one codon for an amino acid, a mutation in the third base of a codon will most likely not cause the wrong amino acid to be put into the chain. </span>
