Answer:
The correct answer is option b. "Alpha eventually replaced by theta".
Explanation:
Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.
First one i thnk???

Answer:
Two proteins that are present inside the same cell perform different functions because both proteins have different amino acid composition.
Explanation:
Amino acid is the building blocks of protein. Different proteins perform different functions due to their composition. These proteins are formed by the instructions given to the ribosome of the cell.
As the ribosome reads each codon of mRNA, it directs tRNA to bring the specified amino acid into the ribosome. Each tRNA molecule carries<span> just one kind of amino acid. In addition, each tRNA molecule has </span>three unpaired bases<span>, </span>collectively called the anticodon<span>—which is complementary to one mRNA codon.</span>
Solar energy<span> drives the </span>cycle by evaporating water<span> from the oceans, lakes, rivers, and even the soil. Other </span>water<span> moves from </span>plants to<span> the atmosphere through the process of transpiration.</span> Plants put down roots into the soil to draw water and nutrients<span> up into the stems </span>and leaves. Some of this water<span> is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration).
