Answer:

D. archaeal membranes contain L-glycerol.

Explanation:

Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.

The best way to measure an exact volume is with a(n) _____________.
xxTIMURxx [149]
The answer is E, graduated cylinder.

Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.

And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.

And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCT
Margaret [11]

Answer:

A

Explanation:

The correct option would be A.

<em>According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).</em>

Hence;

             A-U

            G-C

            A-U

            A-U

            C-G

            T-A

Therefore, AGAACT would be transcribed to UCUUGA.
