Answer:
The three components of the cell theory state that all living organisms are composed of one or more cells, the cell is the basic unit of structure function and organization. and all cells come from pre existing cells Hopefully this helps!
An action potential traveling along the entire length of an axon demonstrates <u>continuous</u> propagation.
Propagation of action potential:
- An action potential is created by the rapid input of Na+ ions and the slightly slower outflow of K+ ions.
- Action potential initiation occurs in the axon's first segment, and as action potentials spread throughout the axon, cells can convey their output to synapses located further distant from the cell.
- The action potential conducts continuously in unmyelinated axons, whereas it conducts rapidly and saltatorily in myelinated axons where sodium channels are concentrated near the nodes of Ranvier.
- The action potential always advances in the same direction whenever a local current begins to form due to the prior axon segment still being in the absolute refractory period. As a result, action potentials travel away from the location of their generation and do not change course.

Answer:
Explanation:
The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.
The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent during copulation giving rise to an individual that is heterozygous for the trait
For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.
