In response to a threat, we perspire, breathe more quickly, get goose bumps, and feel nauseated. These responses are:
Answer: sympathetic nervous system
Explanation: because it is the body's rapid involuntary response to dangerous or stressful situations.
Goosebumps are a symptom of a seizure illness termed temporal lobe epilepsy, a sympathetic nervous system disorder, or other brain disorders, albeit they are uncommon. They are also common with heroin or other drug withdrawal.
What cause goose bumps, and feel nauseated in body?The body's quick automatic reaction to hazardous or stressful circumstances is controlled by the sympathetic nervous system.A quick hormone rush raises the body's alertness and heart rate, which boosts the flow of blood to the muscles.
Therefore, In response to a threat, we perspire, breathe more quickly, get goose bumps, and feel nauseated. These responses are Sympathetic nervous system because it is the body's rapid involuntary response to dangerous or stressful situations.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.

Which process occurs at location W? precipitation evaporation condensation transpiration.
Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.

The epicenter of an earthquake is located 6,500 kilometers away from a seismic station. If the first S-wave arrived at this seismic station at 1:30 p.m., at what time did the first P-wave arrive?
Based on the epicenter and the time of the arrival of the first S-wave, the first P-wave will arrive at 1:22 pm.
From the information given, it was stated that the epicenter of an earthquake is located 6,500 kilometers away from a seismic station and that the first S-wave arrived at this seismic station at 1:30 p.m.
Therefore, it should be noted that the first P-wave will have arrived 8 minutes earlier. This will be:

Answer:
64
Explanation:
4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

when a tautomeric shift occurs, what is true about the resulting mutation?
When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.
A tautomeric shift can be defined as a temporary change in the nucleotide base structure.
A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
