When making gametes, some will contain the necessary amount of chromosomes while others will not
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
Answer:
Microscopic marine phytoplankton play a critical role in regulating todays carbon cycle yet not enough is known about the process. These tiny organisms consume carbon dioxide from atmosphere and move it to marine sediments in deep ocean. And this process is also known as biological pump<em>.</em>
