Nucleotides are monomers composed of sugar and phosphate groups and a nitrogenated base. Several nucleotides compose DNA and RNA.

<h3>What are nucleotids?</h3>

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.

Several monomers comprise a polymer. In this way, several nucleotides joined by their extremes compose the nucleic acids.

Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base. These are purines and pyrimidines.

DNA ⇒ Adenine, Guanine, Thymine, and Cytosine.

RNA ⇒ Adenine, Guanine, Uracyl, and Cytosine

Adenine pairs with thymine or uracil, while guanine pairs with cytosine.

Sugar group: Sugar is always a pentose.

DNA sugar group contains deoxyribose, with hydroxyl modifications.

RNA sugar group contains ribose with no hydroxyl modifications.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information necessary to carry out cellular functions.

Tcs food must be cooled to what temperature in the first two hours

ValentinkaMS [17]

TCS food must be cooled from 135 to 70 DEGREE FAHRENHEIT in the first two hours.
TCS foods are those foods which require time-temperature control in order to prevent the growth of microbes and production of toxins in the foods. These foods are more likely to become unsafe than other foods because they allow rapid growth of micro organism.

Which component of the electrocardiogram represents the duration of ventricular contraction?

Advocard [28]

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. Oxygen wil

Juli2301 [7.4K]

The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.

Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
