What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Answers

Answer:

Binding of   ACh (acetylcholine)    to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Hence , the answer is  ACh (acetylcholine) .

What is the use of reverse transcriptase?

Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.

Therefore, The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?

Answers

Answer:

The Golgi apparatus plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.

 The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.
