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.
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
Answer:
When there is no sunlight and they undergo cellular respiration
Explanation:
Plants respire to get energy like animals. In this chemical process, glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. See the diagram below
