The right answer is A) DNA.
During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.
Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
