Double-blind design: this is how the study will be conducted. This means that in this study, participants will know which treatments are being applied to each participant. In this case, the researcher can hire a doctor or health professional who can deliver the different treatments to the participants without the researcher and the participants themselves knowing what treatment is being delivered and which participants are not receiving any treatment.
Antagonist: It will be a substance used to establish connections in the participants' neurological receptors, but without activating these receptors and preventing any other substance from activating them.
Acetylcholine: Will be the neurotransmitter tested in treatments, as it is the main neurotransmitter often related to the symptoms of Parkinson's disease, alzheimer's disease, multiple sclerosis and schizophrenia
Positron Emission Tomography (PET): It will allow the visualization of images that will allow the evaluation of the functioning of the neurotransmitters related to each tested treatment.
Blood-brain barrier: It will allow the assessment of the metabolic function of the participants' brain, as it protects the nervous system from toxic and harmful substances. This cerebral metabolic function will be evaluated in relation to each treatment applied.
Myelin sheath: is the protective layer of nerve cells. It is usually damaged in people who have Parkinson's disease, alzheimer's disease, multiple sclerosis and schizophrenia, for this reason, it will allow the assessment of their protection in relation to each treatment tested.
2. Flooding because is the answer to the question ok
Understandable. that's the answer because Lucid means clearly or easy to understand.
The boer war, if it happens (hopefully not), will have devastating consequences, first for RSA itself (Swaziland and Lesotho in package with it) where there will be lot of casualties and the economy will go down significantly, then an even bigger problem on a bigger scale may emerge because the treatment towards white people in Africa in multiple countries is on a primitive level, so a chain reaction is almost certain, which can push big portion of the continent into war if and when the world power houses intervene.
Britain's reputation as a world superpower will be affected positively if it prevents the war and impose themselves as a big factor that should be feared and thus calm down the tensions, or negatively if it allows a war to break down.
Answer:
Part A;
k = -1
Part B
k = -4
Part C
g(x) = 3ˣ - 1
h(x) = 
Explanation:
The parent function of the graph, is f(x) = 3ˣ
Part A;
g(x) = f(x) + k
When x = 0, f(x) = 3⁰ = 1
g(x) = f(x) + k = 
+ k
Therefore;
When x = 0, g(0) = f(0) + k = 
+ k = k
From the graph, g(0) = -1, therefore;
g(0) = -1 = k
k = -1
Part B
h(x) = f(x + k)
When x = 4, h(4) = f(4 + k) = 
From the graph, h(4) = 1, therefore;
h(4) = 1 =
Therefore, we get;
ln(1) = (4 + k)·ln(3)
4 + k = ln(1)/ln(3) = 0
k = 0 - 4 = -4
k = -4
Part C
g(x) = f(x) + k
f(x) = 3ˣ, and k = -1
Therefore;
g(x) = 3ˣ - 1
h(x) = f(x + k)
f(x) = 3ˣ, and k = -4
Therefore;
h(x) =
