Muscle is composed of small units known as myofibril which itself composed of cylindrical bundles of thread like filaments; thick filament and thin filament known as myosin and actin respectively.
These filaments make up a myofibril which is organized into a chain of contractile units called sarcomeres. . There are two more proteins known as titin and nebulin which also contribute to the structure of sarcomere.
The function of the muscle is to contract and these filaments play a major role in it
<span>Mendel's law or principle that explains that traits are passed from parents to offspring individually instead of pairs, groups, and/or sets B-The law of independent assortment. Mendel's Law of heredity includes the Law of segregation and the Law of independent assortment. The Law of segregation explains that alleles separate (segregate) during gamete formation and that offspring inherit only one allele from each parent. The Law of independent assortment explains that traits are passed individually and that they are independent of the inheritance of other traits.</span>
Answer: we would die
Explanation:
Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.
The correct answer will be
1. Motor neuron
2. Spinal cord to muscle
In a Reflex arc, the Motor neuron carries the action potential from the Spinal cord to muscle.
The following are the components of a reflex arc:
- A stimulus-detecting receptor
- A sensory neuron that will transmit the data to the spinal cord.
- A processing interneuron for the data (not present in all reflexes)
- A neuron that transmits signals to an effector organ
- An organ that carries out the reaction action.
A brain circuit that manages a reflex is called a reflex arc. In vertebrates, the majority of sensory neurons synapse in the spinal cord rather than passing directly into the brain.
When Juan picks up a steel utensil the receptor detects the stimulus. A sensory neuron transmits the data to motor neuron which activates spinal cord which then signals the effector organ to carry out the reaction action i.e., Juan immediately drops the hot Utensil.
