Answer:
false
Explanation:
Describe step by step how a signal is transmitted from your brain and nervous system into an actual contraction of the muscles. Your explanation should start at the stage where the nervous system interacts with the muscles and should discuss the role of the neuromuscular junction, neurotransmitter, and motor neurons.
Answer:
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
Explanation:
Explanation:
The first step is the muscle fiber is activated by the motor neuron when the acetylcholine crosses the synaptic gap, which causes the heads of the myofibrils to bind. This activation initiates by the release of calcium ions within the muscle fibers. The neuromuscular junction furthers the reaction by assisting in message transmission, along with the neurotransmitter which helps with transmitting messages between neurons and the muscles.
Second, the myofibril binds to the next myofibril in a chain-like reaction.
Third, as one myofibril joins the next, they shorten and slide closer together, causing the muscle to contract.
Fourth, the contraction ends when the acetylcholine breaks down through its natural cycle.

Consider five other traits that Mendel investigated.
Explain how you could repeat Mendel's procedure for one of these traits and
what the likely results would be of your investigation.
Answer:
Geneticists use their own unique shorthand when analyzing the results from a genetic cross (a mating between two organisms with characteristics that scientists want to study). For example, they might use a letter of the alphabet to stand for each gene, capitalizing the letter for dominant alleles and using lowercase to represent recessive alleles. The same letter of the alphabet is used for each allele to show that they’re variations of the same gene.
Mendel studied characters such as- seed form, seed color, flower color, pods form, pod color, stem height, and flower position. When two homozygous individuals were crossed then all the offsprings produced were heterozygous.
What is Mendel's law?
Mendel did experiment on garden pea plant (pisum sativum) plant and come to the conclusion that there is a pair of alleles for each and every character. The alleles are of two types- Dominant and recessive. Dominant characters are present in all the offsprings of F1 generation and recessive character is present in the F2 generation.
The following traits were studied by Mendel are mentioned below:
1. Form of ripe seed (R) – smooth or wrinkled
2. Color of seed albumen (Y) – yellow or green
3. Color of flower (P) – purple or white
4. Form of ripe pods (I) – inflated or constricted
5. Color of unripe pods (G) – green or yellow
6. Position of flowers (A) – axial or terminal
7. Length of stem (T) – tall or dwarf
The two homozygous parents are crossed which gives the F1 offsprings. For example, by taking the plant height as a character, the homozygous dominant parent (TT) is crossed with a homozygous recessive parent (tt), then probability of offsprings in the F1 generation are as follows:
100% of the offsprings will be heterozygous tall (dominant) plants.
