Answer:

IQ and head size are positively correlated.            

Explanation:

Correlational research: In scientific and psychological research, The term, "correlational research" is determined as one of the different types of "non-experimental research" methods in which an investigation, researcher, or experimenter tend to measure or evaluate two different variables and therefore assess and understands the "statistical relationship" between the given variables in the absence of any influence from the extraneous variable.

Positive correlation: Relationship between two different variables that move in a similar direction.

In the question above, Joshua can conclude IQ and head size are being positively correlated.

Agata [3.3K]
In Europe, most revolutionary conflicts attempted to eliminate the monarchy and to remove the influence of religion.

Some researchers theorize that it exists possible that the timing of the onset of schizophrenic symptoms in adolescence and young adulthood stands linked to aberrant Synaptic pruning during adolescence.

<h3>What is synaptic pruning?</h3>

In the brain, synaptic pruning takes place naturally between early childhood and adulthood. The brain prunes additional synapses throughout this process. Synapses are parts of the brain that allow one neuron to communicate with another neuron electrically or chemically.

Synapse-level modifications lead to neuronal reorganization that almost certainly has significant effects on both healthy and pathological brain function. The improvement in cognitive abilities we experience in our late teens or early 20s may be the result of brain circuitry simplification.

Synaptic pruning is believed to aid the brain's transition from childhood, when it is easily able to learn and form new connections, to adulthood, when it is slightly more structurally established yet can concentrate on one issue for longer periods of time and perform more complicated mental processes.

Synaptic pruning, a process that occurs as you sleep, causes your brain to shrink. But it's not as horrible or frightening as it seems. This is a fully normal process that is crucial for memory and learning. The majority of this pruning happens in early adulthood and youth.

Hence, Some researchers theorize that it exists possible that the timing of the onset of schizophrenic symptoms in adolescence and young adulthood stands linked to aberrant Synaptic pruning during adolescence.

"As their name suggests, calcium ion channel blockers block calcium ion channels in the sarcolemma of pacemaker and contractile
Semmy [17]

Answer:

There would be a decrease in contractility

Explanation:

Since the calcium ion channel blockers slow down the calcium ion and they do not affect the potassium ion efflux which thus leads to a quick repolarization of the cell. This causes the muscle cell to lose the ability to sustain the excitability needed to keep it in a contracted state.
