The point where the axon terminal synapses with the muscle fiber sarcolemma is called the neuromuscular junction.
The neuromuscular junction (NMJ) is a highly specialized synapse between a motor neuron nerve terminal and its muscle fiber that are responsible for converting electrical impulses generated by the motor neuron into electrical activity in the muscle fibers. On arrival of the motor nerve action potential, calcium enters the presynaptic terminal, which leads to the release of the neurotransmitter acetylcholine (ACh).
ACh crosses the synaptic gap and binds to ACh receptors tightly clustered on the surface of the muscle fiber, this leads to the endplate potential which initiates the muscle action potential that results in muscle contraction.

A wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.
Answers
Answer:
Set of crosses:
Wild-type male x light-green female
Light-green male x wild-type female
Explanation:
Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:
- Wild-type male x light-green female >> offspring 100% light green
- Light-green male x wild-type female >> offspring 100 % wild-type
Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:
1- When wild type is dominant:
- Wild-type male x light-green female >> offspring 100% wild type
- Light-green male x wild-type female >> offspring 100% wild-type
2- When light-green is dominant:
- Wild-type male x light-green female >> offspring 100% light-green
- Light-green male x wild-type female >> offspring 100% light green

Answers
Answer: Base Pair Deletion
Explanation:
If the normal allele has more than the mutated then that means nucleotides were lost so a deletion occurred.
Answer:Base Pair Deletion
Explanation:
We know this because it is stated that the normal gene has more base pairs than the mutated gene. In other words, the mutated gene has less base pairs than the normal gene, which means that base pairs must have been deleted during the mutation.

how are the order of condons determined
Answers
Overall, the order of codons is determined by the genetic code, which specifies how nucleotide triplets are translated into amino acids. The order of codons is crucial because it determines the sequence of amino acids in a protein, which in turn determines its structure and function.
In genetics, a codon is a three-nucleotide sequence in RNA or DNA that encodes a single amino acid or signals the end of the amino acid chain during translation.
The order of codons is crucial because it specifies the sequence of amino acids in a protein, which in turn determines its structure and function.
The order of codons is determined by the genetic code, which is a set of rules that specifies how nucleotide triplets are translated into amino acids.
The genetic code is nearly universal, meaning that the same codons code for the same amino acids in almost all organisms, from bacteria to humans.
The genetic code is degenerate, meaning that multiple codons can code for the same amino acid.
For example, the amino acid leucine can be encoded by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.
The genetic code also has several codons that signal the end of a protein. These codons are known as stop codons, and they include UAA, UAG, and UGA.
The order of codons in DNA is determined by the sequence of nucleotides in the DNA molecule.
The order of codons in RNA is determined by the transcription of DNA into RNA, which involves the complementary base pairing of nucleotides.

Which organisms can reproduce using the process of fragmentation
Answers
Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.
In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.
Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.
Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms, annelid worms, sponges, and sea stars.

https://brainly.com/question/29633695
The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.
Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.
Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.
Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.
Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

And
What is the process of Sexual reproduction? Honey Bees
Answers
Answer:
ASEXUAL
female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.
SEXUAL
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

Accepted theories may be modified or overturned as new evidence and perspective emerges. Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more
What is Scientific theory ?Ideally, a scientific theory changes because new information arises that either discredits it or forces it to be modified to act as a better explanation. Some theories which seemed correct at the time are disproven by later findings with better, more accurate instruments.
As technology develops more data can be collected and new types of observations made. A hypothesis is a testable explanation of an observed event. New data that contradicts a hypothesis may lead to a new scientific explanation. The hypothesis is changed.
The power of a hypothesis test is affected by three factors.
Sample size (n). Other things being equal, the greater the sample size, the greater the power of the test.
Significance level (α). The lower the significance level, the lower the power of the test.

Answers
A population in biology is a collection of organisms belonging to the same species that coexist and interact in the same habitat. A population might consist of plants, animals, or microbes and can range in size from a few to millions of individuals.
We must utilize the logistic growth function to solve for the starting population (P0) of butterflies with t=0 in order to determine the initial population of butterflies.
\(f(t) = 320/1 + 7.0e^(^-^0^.^2^7^t^)\)
When t=0,
\(f(0) = 320/1 + 7.0e^(^-^0^.^2^7^*^0)\\f(0) = 320/1 + 7.0e^(^0^)\\f(0) = 320/1 + 7.0(1)\\f(0) = 320 + 7.0 f(0) = 327\)
