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.

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

Mark as brainiest please
