Mutation Classes

Class I - Gene contains a stop signal that prevents CFTR from being made.

Class II - CFTR is made, but does not reach the cell membrane

Class III - CFTR is made and in the right place, but does not function normally

Class IV - Channel does not move substances efficiently or at all

Class V - CFTR is made in smaller than normal quantities

ice floats on water because ice is less dense than water, how is this helpful to fish tnat live in a lake

Answers

The helps fish in 2 ways. Since water can have a high amount of energy gained or loss and not change, the entire lake will not freeze. Thus, fish will still be able to live in liquid water. The ice also, as strange as it may sound, provide insulation for the fish, so they don’t freeze. The water can do this because it requires a huge change in energy to counteract the hydrogen bonds.

Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis

Answers

Interphase:

Is known as the resting stage. Replication of DNA occurs.

- G1

-S

-G2

Prophase:

The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.

Metaphase:

The chromosomes line up in the centre of the cell.

Anaphase:

This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.

Telophase:

The nuclear membrane is reformed.

Answers

Answer:

If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

Answers

Breaking down glucose molecules

The energy provided by ATP is driven by the breakdown of glucose molecules. Thus, option D is correct.

ATP or Adenosine triphosphate is the energy molecule that is able to provide energy to the body. Varying pathways and cycles in the cell produce ATP.

Which molecules produce ATP?

ATP production is carried out in the degradation of the complex molecules by the cell. The cycle is operated primarily in the cell for the production of ATP in glycolysis.

The ATP is produced in the glycolysis cycle with the breakdown of glucose molecules. Thus, option D is correct.

name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule

Answers

The replication, transcription process mostly occurs in the nucleus. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA.

You’re welcome

Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.

Transcription is the process that occurs in the nucleus.

What is the process that synthesizes the mRNA?

mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.

The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.

One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.

Therefore, transcription results in the formation of the mRNA.
