The cell membrane lets substances come in and out of the cell. This is found in plant and animal cells. The cell wall acts like a barrier or a wall for the cell, and this is only found in a plant cell. The nucleus is basically the 'brain' of the cell. This is found in both plant and animal cells. It is only found in eukaryotes. The cytoplasm is a gel-like fluid that fills up the cell.
Answer:
C. Tyrone:
- Information stored in DNA
- Transcription
- Translation
- Gene Expression
Explanation:
Central Dogma of Molecular Biology:
- The central dogma of molecular biology is the scheme that illustrates the flow of genetic information from DNA to RNA to protein. The processes include:
- Genetic information is stored in DNA in the form of nucleotide bases.
- This DNA sequence is converted into RNA sequence through a process called transcription. Transcription produces an mRNA which is complementary to the DNA sequence of the gene but contains ribonucleotides.
- mRNA is read in the form of codons which are triplet codes of nucleotide bases specific for a specific amino acid. These codons are decoded and translated into proteins through the process of translation.
- Both processes of transcription and translation combined with post-translational modifications of proteins is termed as gene expression.

Explanation:
<em>decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration. in some conditions, decomposition is blocked. the plant and animal material may then be available as fossil fuel in the future for combustion.</em>
Answer:
It would block the generation of action potential in the motor neurons
Explanation:
Tetrodotoxin (TTX) is a toxic compound found in the Pufferfish which could affect the neuronal signalling in the humans.
The tetrodotoxin binds to the sodium channels present in the motor neurons in the soma region of the neuron where the binding of the tetrodotoxin to the sodium channels inhibits the inward flow of the sodium ions. The reduction in the influx of sodium ions does not change the depolarization of the cell membrane and hence action potential is not generated in the motor neuron.
Thus, It would block the generation of the action potential in the motor neurons is the correct answer.
The body wall<span> of a star fish is made up of a thin cuticle, an epidermis with a single layer of cells, a thick dermis composed of connective tissue and a thin coelomic myoepithelial layer, which allows the longitudinal and circular musculature.</span>
