Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
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

Well earth's density is 5.51 g/cm³....and Jupiter's density is 1.33 g/cm³....So add those together and you get 6.84 g/cm³
