Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre. Where they sit together is called a neuromuscular junction.
All of the body's muscles and the nerves that supply them are part of the neuromuscular system. The brain and muscles must communicate with each other for the body to move. By sending signals from the brain to various bodily organs, the nervous system establishes the connection between ideas and deeds. The neuromuscular system, which is made up of nerves and muscles, controls how the body moves and other processes like breathing.
Neurons are the cells found in nerves. Neurons in the spinal cord transmit information from the brain. Motor neurons are the neurons that transmit these signals to the muscles.
A muscle fiber is located extremely close to each motor neuron terminal. A neuromuscular junction is the location of their intersection. A substance is released by the motor neurons and is then taken up by the muscle fiber. By instructing the muscle fiber to contract, this causes the muscles to contract.

Do snails reproduce quickly?
Because they may reproduce without a partner, snails do grow in number quickly. Snails only fertilize their own eggs.
How many times do snails mate?Snails have a monthly reproductive rate of up to once when the right circumstances are present (warm temperature, high humidity). Garden snails can lay an average of 86 eggs every reproductive cycle, and because they typically have five reproductive cycles year, this equates to 430 eggs per snail per year.
Due to an availability of food, snail populations are on the rise. Sometimes they consume the same foods that your fish do. Because snails multiply more quickly when fish are overfed, there is a type of cascading effect once this process starts.

What are the disorder caused by mutation?
The disorders caused by mutations are called genetic disorders.
What are genetic mutations?Genetic mutations are alterations in the genetic material of an organism due to changes in the linear order of nucleotide bases in the genome that form the genetic material of the cells of such organism.
Moreover, genetic mutations cause genetic disorders that are inherited through the germinal line when these mutations are able to pass from parents to offspring, in a process that involves the transference of genetic material from the egg cell or the sperm cell to the first somatic cell which is called the zygote.
Therefore, with this data, we can see that genetic mutations are able to cause genetic disorders that are alterations in the genetic material passed from parents to offspring through the germinal line, i.e. by the egg cell or the spermatic gametic cells

Animal cells are cells with a complex nucleus with a nuclear envelope consisting of two membranes. Animal cells belong to the eukaryotic cell type.
Animal cells have three main parts: the plasma membrane, the nucleus and the cytoplasm. The plasma membrane is the outermost part of the cell, while the cytoplasm is the liquid inside the cell. The nucleus in animal cells is covered by a nuclear envelope and within it is the nucleolus. The nucleolus functions for protein synthesis.
Some of the organelles in animal cells, namely vacuoles, are liquid bounded by a membrane in the form of inward folds. Centrioles are collections of microtubules that act as poles of cell division. Ribosomes in animal cells function for the process of protein synthesis. The cytoskeleton is a cell framework consisting of microtubules, acttin filaments, and intermediate filaments. Mitochondria are the cell's energy-producing organelles with a two-layer, indented inner membrane and a broad, smooth membrane. The endoplasmic reticulum is a hollow tube.

How do coral reefs benefit the environment in terms of biodiversity?
Biodiversity is the variety of life on Earth across all ecological roles. Biodiversity hotspots are areas that have an increased number of species and high numbers of individual organisms in those species. Examples of biodiversity hot spots are tropical rainforests and coral reefs.
Coral reefs have high levels of biodiversity because of their huge microhabitats, high levels of nutrients, and high levels of sunlight and warm temperatures. Coral reefs are home to many microhabitats. These are small habitats within an ecosystem that help unique niches for organisms to evolve. They are also located in warm, shallow waters rich in nutrients. The high level of sunlight in these areas promotes plant and algae growth which can provide a strong base for the ecosystem.

The DNA compliment of the above-mentioned strand is ATA-ATC-TAA-TGA (option C).
What is DNA replication?DNA replication is the process by which DNA makes a copy of itself during cell division.
DNA replication is a very important process that must occur prior to cell division because it ensures that each daughter cell receives the correct amount of genetic material.
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule with the aid of an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).
The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
Since Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C), this means that if a DNA strand of TAT-TAG-ATT-ACA undergoes replication, the complimentary DNA strand will be as follows: ATA-ATC-TAA-TGA.

Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.

how would the membrane composition of a native grass found in very warm soil around hot springs compare with that of native grass found in cooler soil? explain
The grass in the warm soil has more saturated fatty acid in its plasma membrane, whereas the grass in the native relatively cool region has more unsaturated fatty acid.
Because fatty acids remain fluid at lower temperatures, grasses living in cooler regions are predicted to contain more unsaturated fatty acids in their membranes. Hot-weather grasses are anticipated to have more saturated fatty acids, which allows the fatty acids to "stack" closer together, making the plasma membranes less fluid and thus assisting them to remain untouched at elevated temperature.
During cold acclimation, membrane lipids have become more unsaturated, and a reverse reaction transpired during warm acclimation. Membrane lipids, on the other hand, had shown no warm acclimation, which could be attributed to the moderate change in temperature.

95% of the time required to complete a full cycle, the cells typically spend in interphase.
A cell's growth and division are governed by a series of events known as the cell cycle. The majority of a cell's time is spent in interphase, where it grows, replicates its chromosomes, and gets ready for cell division. After that, the cell enters mitosis, completes its division, and leaves interphase. Interphase (G1, S, and G2) precedes the mitotic phase (M, mitosis, and cytokinesis) in the cell cycle.
Total time of the cell cycle = M + G1 + S + G2
= 1 + 9 + 7 + 3
= 20 hours
As is well known, DNA synthesis and cell growth take place during the interphase.
Therefore, Interphase time = = G1 + S + G2
= 9 + 7 + 3
