The correct answer is
B. the thalamus→amygdala pathway
The neural pathway carries crude information about a threatening stimulus and activates a rapid instinctual alarm response is the thalamus→amygdala pathway
The thalamus→amygdala pathway is also known as the the path of fear. The thalamus transfers signal to other parts of the brain that causes the release of adrenaline and stress hormones.
Answer:
NEUROTRANSMITTER
Explanation:
Imbalances with neurotransmitter results in depression, anxiety and other mood disorders. Examples of neurotransmitters that affects mood are Serotonin, Dopamine, GABA and Norepinephrine.
The Acetylcholine and norepinephrine are known as the excitatory neurotransmitters and the dopamine, serotonin, and GABA are known inhibitory neurotransmitter.
A Neurotransmitter influences behaviour by affecting neurons in a specific portion of the brain.
Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.
iii) Fragile teeth.
iv) Stiff joints.
Answer:
8.800s
Explanation:
When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.
First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation
T = 2π×√(Lo/g)..... (1)
Let's make Lo the subject of the formulae
Lo = gTo^2/4π^2 ..... (2)
Let's put our values into equation (2) to get Lo
Lo = gTo^2/4π^2
= (9.8m/s^2)(8.90s)^2
------------------------------
4π^2
= 19.663m
Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be
L = Lo - (0.44m)
= 19.663m - 0.44m
= 19.223m
Now let use the value of L into equation (1) to get the period T after raising
T = 2π×√(L/g)
= 2π×√(19.223m/9.8m/s^2)
= 8.800s
Answer: The open ocean zone lies beyond the continental slope and contains 65% of the water in the oceans. This zone is divided further into three subzones. The sunlit zone is where photosynthesis takes place. Plankton and jellyfish are drifters that inhabit this zone.
