Answer:

The correct answer is : D. isoelectric line.

Explanation:

ECG interpretation requires the analysis of various waves and curves and their characteristic.  There are different type of waves and curves that can be found and analyzed in ECG such as P- wave, T wave, PR interval and others.

All these curves and interval shows electrical activities generating by the repolarization and depolarization of atria and ventricles of heart.

Base line or isoelectric line shows a flat line which have no electric activity as there is no negative or positive charge to create deflection.

Thus, the correct answer is : D. isoelectric line.

What would be of most importance to goblet cells and other glandular epithelia?
konstantin123 [22]

The given question is incomplete as options are not provided, however the options  are as follows :

- Golgi bodies

-lysosomes

-microvilli

-multiple nuclei

Answer:

The correct answer is - golgi bodies.

Explanation:

Goblet cells and glandular epithelial cells are cells that produce and secretes a specific type of products that are termed as the mucin to protect the skin and layer mucous membrane they place.

These cells are characterized by a large amount of Golgi body and endoplasmic reticulum as they are involved in the exocytic pathway which means they secrete, glycoproteins, mucin, and other substances. Golgi bodies needed to modify, synthesis, and secretion.

Thus, the correct answer is - golgi bodies.

What cellular process(es) is/are responsible for the increase in protein content associated with the gap phases of the cell cycl
Dafna11 [192]

Answer:

Protein/enzyme synthesis

Explanation:

<em>The process of synthesis of protein in the cell is mainly responsible for the increase in the protein content of the cell.</em>

<em>The process which is also known as the translation process of gene expression takes place at the G1 and G2 phases of the interphase of the cell cycle.</em>

During protein synthesis, mRNA synthesized in the nucleus are transported to the cytoplasm and the genetic codes on the mRNA are translated into their respective amino acids linked together by polypeptide bonds. The protein are then folded in specific ways for specific enzymes.

NeX [460]

Answer:

Denaturation occurs.

Explanation:

When a chemical relaxer and heat applied to a curly hair, the protein present inside your hair get denature. Due to this denaturation of protein in the hair, the hair are soft and flexible which can be converted into any direction and different styles can be done. If chemical perm or relaxer is applied to straight hairs, it also denature the protein and make the hair curly.
