Identify the structures of the neuromuscular junction
The structures of the neuromuscular junction are apresynaptic region; synaptic cleft and postsynaptic region.
What is the neuromuscular junction?The neuromuscular junction is where a nerve ending joins skeletal muscle tissue. Muscle contraction signals are initiated by chemicals, such as the neurotransmitter acetylcholine, that are transferred from the nerve ending, or motor end plate, to the muscle.
The importance of neuromuscular junctions is the synapse region between skeletal striated muscle fiber and motor axon; whose function is the transmission of the nerve impulse.

Answer:
100
Explanation:
there is a certain amount of food and resources to sustain a certain amount of individuals in a population. Since the individuals exceeds the amount of resources at 100,000 individuals you would usually see the death rate higher than birth rates to balance out the number of individuals to the number of resources so there is enough for all the individuals there.

RNA polymerase finds promotor
RNA polymerase adds new nucleotides
RNA polymerase unwinds strand
transcript is released
RNA polymerase reaches termination site
SUBMIT
Answer:
1.) RNA polymerase find promotor
2.) RNA polymerase unwinds strand
3.) RNA polymerase adds new nucleotides
4.) RNA polymerase reaches termination site
5.) Transcript is released
The correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.
The process of transcription involves the synthesis of RNA from a DNA template.
RNA polymerase unwinds strand: RNA polymerase recognizes the DNA strand that needs to be transcribed and unwinds the double helix, separating the two DNA strands.
RNA polymerase finds promoter: RNA polymerase searches for and binds to a specific DNA sequence called the promoter, which marks the starting point for transcription.
RNA polymerase adds new nucleotides: Once bound to the promoter, RNA polymerase begins moving along the DNA strand, reading the template strand and adding complementary RNA nucleotides. This process is known as elongation.
The transcript is released: As RNA polymerase moves along the DNA template, it continues adding nucleotides to the growing RNA molecule. Eventually, it reaches a termination site on the DNA, signaling the end of the gene or region being transcribed. At this point, the RNA polymerase releases the completed RNA transcript.
RNA polymerase reaches the termination site: The termination site is a specific DNA sequence that signals the end of transcription. Once RNA polymerase reaches this site, it detaches from the DNA template, and the RNA transcript is released.
Thus, the correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.

During which phase of the cell is a cells DNA copied
Explanation:
Hi there!
Cell cycle has 2 phases (i.e M-phase and Inter-phase). Interphase is considered to be the longest phase. Interphase also has G1-phase, S-phase and G2-phase. In cell cycle while moving from M-phase it has two option either to go in G1-phase or G0 phase. It it goes to G0-phase it doesn't go under cell division but if it goes to G1-phase it starts to prepare materials required to replicate or copy DNA. After preparing all the material it goes in S-phase and copies DNA. It doesn't go to G2-phase until it copies DNA perfectly. Then it goes to G2-phase. In this phase it prepares material for replication of other cell organelles.
Therefore, DNA is copied in S-phase.
Hope it helps!
Answer:
S phase (Synthesis phase)
Explanation:
DNA is copied during interphase (S phase) before mitosis and just before meiosis. Mitosis is usually defined as the usual method of cell division, characterized typically by the resolving of the chromatin of the the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell. Meiosis is usually defined as part of the process of gamete formation, consisting of chromosome conjugation and two cell divisions, in the course of which the diploid chromosome number become reduced to the haploid (A single set of chromosomes). In human, mitosis produces diploid daughter cells which have the same number of chromosomes as the parent cell. Meiosis produces gametes (sperm or egg) which are haploid, meaning these cells have half the number of chromosomes as body cells such as skin cells. DNA is copies using a process called semiconservative replication.
More information:
What is DNA replication? What is its importance?A double-stranded DNA molecule is duplicated during DNA replication (by a variety of proteins) to create an identical double-stranded DNA molecule (so whereas the cell started with one copy, it ended up with two identical copies). Cell division would not be possible without DNA replication, hence it is crucial. In other words, either one cell would receive all the DNA while the other received none, preventing true cell division, or each cell would receive just half the DNA it requires, preventing the daughter cells from surviving (also leading to death of both daughter cells). DNA replication allows cells to replicate their whole set of DNA so that when they divide, each new cell has its own complete set of DNA. In theory, this allows for endless cell division.
