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.

Improve the student’s model of gas exchange by drawing the missing component.
larisa [96]

Answer:

The diagram can be improved by:

                                  Lungs

                                       ↓

                                   oxygen

                                       ↓

                      Red blood cells (carrying oxygen)

                                       ↓

                  Organs (like stomach and liver etc) from where carbon    

                               is taken and oxygen is supplied

                                         ↓

                   RBC's carrying Carbon dioxide to the lungs

The component which is missing in the diagram are the organs where exchange of gases occurs. The red blood cells carry oxygenated blood from the lungs to all parts of the body and carries the wast carbon dioxide gas from them back to the lungs. The carbon dioxide is then exhaled by the lungs.

How will the movement of water affect a survey if it is transferred from a hypotonic solution to a hypertonic solution?
Inga [223]

Answer:

The cell will shrink

Explanation:

In an hypotonic solution, water moves into the cell through the process of osmosis. This shall be due to the high concentration of water in the hypotonic solution than that in the cytoplasm.

Due to this movement, the cell bulges out.

If the cell is transferred to a hypertonic solution, water shall move out of the cell thereby making the cell shrink. This is because water concentration in the cytoplasm shall be higher than that in the hypertonic solution.

Effect to the survey shall be an experience of the exact opposite of the previous immersion.
