Answer:
Explanation:
Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species
Botulinum toxin commonly acts by binding to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. Through this mechanism, muscle movement is inhibited in the area it is injected to.
Answer:
they move to an area with lower concentration.
Explanation:
Air particles always travel from an area where they are high in concentration to an area where they are low in concentration. as we can see that on the left hand side the numbers of o2 and co2 molecules are balanced.
It could be the cell membrane which is a barrier, thinner than the cell wall, that protects the cell and controls transport from within and outside the cell.
Dorothy Mary Crowfoot Hodgkin was the first to develop protein crystallography and she won Nobel Prize for that discovery ( third woman to win the Nobel Prize in Chemistry). Hodgkin confirmed the structure of penicillin but also realized the structure of vitamin B12 by x-ray crystallography analysis. She advanced the classical technique of X-ray crystallography.
My answer -
<span> Biology is a
natural science concerned with the study of life and living organisms,
including their structure, function, growth, origin, evolution,
distribution, and taxonomy. Biology is a vast subject containing many
subdivisions, topics, and disciplines.
P.S
Glad to help you have an AWESOME!! day :)
