When a potassium ion (K) moves from the soil into the vacuole of a cell on the surface of a root, it must pass through several c
Sindrei [870]

Answer:

C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast

Explanation:

When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.

First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).

Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).

When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.

Questions 1. What is unusual about the Huntingtin "song"?
Katen [24]

Science and art are two areas that can contain genius, so these two factors were added to the construction of the Huntingtin "song", in order to answer this question we need to know that ....

<h3>Huntingtin "song"</h3>

A group of researchers explored  this question in a fascinating way. Rie Takahashi, Frank Pettit, and Jefrey Miller at UCLA created a program that  created music from a DNA sequence (a gene) based on the protein that that gene encodes. Te program transcribed  and then translated a gene, producing a protein sequence.

<h3>Huntingtin gene</h3>

The huntingtin gene is the DNA sequence associated with Huntington disease, a very serious, inherited neurological  disorder.

With this information, we can say that what is unusual about the Huntingtin "song" is that the sound transcribed by the gene that contains Huntingtin disease will be a different song than that of people with DNA without this disease.
