A neuron's sodium channels are malfunctioning and will no longer open. How would this prevent the cell from changing its polarity, and why?

Answers

Answer 1
Answer:

The cell will not be able to depolarize due to unavailability of sodium ions.

What is the role of sodium gates in action potential?

  • Sodium voltage-gated channels can be either closed, open, or inactive.
  • Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
  • Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
  • Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
  • A greater amount of sodium will enter the cells as a result, initiating an action potential.
  • Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
  • The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."

Answer 2
Answer:

Answer:

it could not depolarize because the cell cannot become more positively charged.

Explanation:

When sodium gates open, depolarization occurs, changes the charge of the ion from negative to positive. Therefore, if the sodium channels no longer open, the flow of sodium into the cell that changes the charge from - to + and depolarization would not occur.

A group of paleobiologists were studying sedimentary rocks in the Rocky Mountains of North America. What order of organisms would they find in the layers of these sedimentary rocks? All organisms are arranged randomly in the layers of sedimentary rocks./ Newest organisms are at the bottom and the oldest organism is in the top-most layer of the sedimentary rocks. /Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Answers

Sedimentary rocks are rocks that are formed by the deposition of the weathered remains of other rocks. These are mixed sand, mud and pebbles that are laid down in layers and even fossils are found in these rocks. The order of organisms that they would find in the layers of these sedimentary rocks is, oldest organisms are at the bottom and the newest organisms are in the topmost layer of the sedimentary rocks.

The order of organisms that they would find in the layers of these sedimentary rocks is; Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Sedimentary rocks are rocks that are made by the deposition and compression of other rocks or pieces of organic matter (dead plants and animals). According to the law of superposition which states that in a sequence of undisturbed sedimentary layers, the youngest layer is always at the top while the oldest layer is always at the bottom of the sequence. From the question, the organisms are components of the rocks. The oldest organisms will be found at the bottom layer of the sedimentary rocks while the newest organisms are in the topmost layer of the sedimentary rocks.

Which process that occurs in living organisms is SIMILAR to the burning of fossil fuels?

Answers

The answer is respiration.

The burning of fossil fuels is known as combustion. It is often compared with cellular respiration.
The general equation of cellular respiration is:
glucose + oxygen → water + carbon dioxide

The general equation of combustion is:
fuel + oxygen → water + carbon dioxide

Both reactions involve breaking down of large molecules (glucose and fuel) using oxygen into water and carbon dioxide. In both reactions, chemical energy is transformed into more useful form.

Differences between photosynthesis and cellular respiration

Answers

1) Photosynthesis is where glucose is produced while respiration is where glucose is broken down
2) Photosynthesis is endothermic while respiration is exothermic
3) Respiration may need oxygen to occur while Photosynthesis produces oxygen as a by-product
4) Photosynthesis only occurs in organisms that produce chlorophyll (plants and cyanobacteria) while respiration occurs in most cells.
Photosynthesis creates oxygen as a product cellular respiration used oxygen to create carbon dioxide

During the process of _______________, the genetic message from DNA is transformed into mRNA.A) transcription
B) translation
C) translocation
D) transplantation

Answers

Answer: The correct answer for the fill in the blank is A) Transcription.

Transcription is a process in which genetic information ( present in the form of nucleotide sequence) from DNA (deoxyribonucleic acid) is copied into a strand of mRNA (messenger RNA) with the help of enzyme RNA polymerase.

It is the initial process of gene expression.

The mRNA thus formed is further translated to form desirable protein.

Thus, during the process of transcription, the genetic message from DNA is transformed to mRNA.

transcription, the Mrna is copying the DNA
