The correct answer to this open question is the following.
Although the question does not include options, we can say the following.
This is a photograph of !Kung hunter-gatherers, a group of modern foragers. The study of the !Kung and other modern foragers as well as the geometry of ancient bones provide insight into whether people had to work harder to acquire their food as hunter-gatherers or as agriculturalists. The statements that correctly reflect related research findings are the following:
"There is a great deal of variation in how much both hunter-gatherers and agriculturalists work." And "bone signatures in Coastal Georgia indicate a lessened work load with the onset of agriculture."
For the !Kung, the work load heavily depended on the conditions of the environment. They had to consider their living conditions and necessities to know what to do and the way to work to fulfill their necessities. Researcher Christopher Ruff shared important knowledge about how bones found in the Coastal area show that these people had less stress due to the fact that their level of work and general activities were lower. The weather conditions of the region allowed them to grow crops and harvest successfully in the coastal region. Raw materials and natural resources were plenty in this area.
The answer to your question is A
Calcium contributes to the slow inward current which dominates the first one hundred- 2 hundred ms of the motion capability and which helps help the plateau. Growing Cao enhances the sluggish inward modern-day and thereby elevates the plateau.
Motion potentials open voltage-touchy calcium channels in excitable cells, main to an inflow of calcium ions. Calcium ions might also control, amongst others, cellular excitability, neurotransmitter release, or gene transcription.
Neurons talk to every other across synapses. whilst an action potential reaches the presynaptic terminal, it causes neurotransmitters to be launched from the neuron into the synaptic cleft, a 20–40nm gap among the presynaptic axon terminal and the postsynaptic dendrite (often a backbone).
