Answer:
or 308 J
Explanation:
Work in physics is done when an object is moved due to an applied force. But you need to remember that work is only done if there is movement parallel to the direction of the force applied.
Work can be computed with the formula:
W=Fd
Where:
F = Force
d= distance
So your problem gives you:
F = 22 N (Newtos)
d = 14 m (meters)
All you need to do is plug in the values and multiply:
W = F x d
W = 22N x 14m
W = 308 N-m or 308 J (Joules)
Answer:proteins
Explanation:
Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids.
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

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
