False. Only the shape of the organism is visible in rock, no other material (flesh,...) remains
        
             
        
        
        
I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
        
             
        
        
        
Answer:
Explanation:
Crickets give 2 to 3 times better protein than a beef steak.  They also contain fiber, nutrients. 
 
        
             
        
        
        
The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem.  Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia. 
        
             
        
        
        
Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium  ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons  to the tip of the post-synaptic membrane. at the <u>neuromuscular  junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u>   <u>At the tip  of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters,  diffuse through the neuromuscular junction to bind  with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This  stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions  diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is  up to the threshold levels   it  generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP  generation.
