1. 15,000 years ago the humans were still hunter-gatherers. Their daily lives were largely based around one thing, finding enough food to survive through the next few days. This means that they had to constantly be on the move, be it for hunting animals, or for finding rich places with eatable plants. There was lot of walking, running, and scouting involved every day. It was a lifestyle of ''living through the day''.
2. During this period of time, the diet of the humans was consisted of animals they hunted, fish, and plants. There were differences from region to region though, so the people that lived along the coastline based their diet on marine animals, the ones that were living in colder regions were eating mostly meat, while the ones living in forested areas or grasslands had combination of plants and meat. The lifestyle in general was moving from place to place, be it on a daily basis, weakly, or seasonally, depending on the conditions. Some of these people were making small shelters, some of which were retractable and they were moving them with them, while others were using caves.
3. There are many difference between the forager peoples and the agriculturalists. The foragers were nomads, thus they were moving very often from one place to another, while the agriculturalists were having a settled lifestyle. The nomads very often had bad injuries which were often fatal, usually because of hunting, while the agriculturalists had much better health because they had much safer lifestyle. The foragers were not able to produce their own food, but instead they were relying on mother nature, while the agriculturalists were producing their own food and had the food problem solved.
Answer:
Explanation:
Answer: C, Friction
Which force acts when one object moves against another object?
Friction
Your answer is C.
Not all systems perform the same function or use the same organs.
They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis.
Hope this helps :D
Answer:
In a simple synapse, neurotransmitter chemicals are received by the postsynaptic neuron.
Explanation:
The presynaptic membrane is where neurotransmitters are generated, whereas the postsynaptic membrane is where the neurotransmitter receptors have been located. The axon terminal is substantially far more structurally complicated at a neuromuscular junction.
Axon Hillock performs administrative duties by adding up all incoming signals, including inhibitory and stimulating. The action potential gets activated if this total surpasses the limiting threshold.
The neuron's cell body controls the structure of the neuron, houses its genetic material, and supplies energy for its various functions. Additionally, the dendrites' receiving information is processed by the cell body.
Dendrites gather and retain all data coming from the terminal of the axon. Dendrites get any incoming data or signals from the other neuron.
