The statement that says "Psychological disorders can be very difficult to diagnose" is true about diagnosing psychological disorders.
<h2>What are psychological disorders?</h2>
Psychological disorders are those mental, behavioral, emotional and thinking conditions that interfere with the normal performance of the individual in society.
- Mental disorders are psychiatric conditions that are expressed in a syndrome, verifiable from different diagnostic criteria.
- The steps to obtain a diagnosis include a medical history, physical examination, and possibly laboratory tests and a psychological evaluation.
Therefore, we can conclude that a psychological disorder is an alteration in the mental balance of a person that requires specialized attention adapted to the characteristics of the dysfunction.

Answer:
Ion channels in the plasma membrane of the receiving neuron open
Explanation:
Ionotropic receptors are protein structures of the neuronal plasma membrane that function as specific ion channels for certain ions. Depending on the type of ion involved is the nature of the effect that occurs when these channel receptors open. Being ionic channels, these types of receptors participate in the rapid, exciting or inhibitory responses that neurons give.
For now we will refer only to ionotropic excitatory receptors which, by allowing the passage of ions such as sodium or calcium, produce a decrease in membrane potential (hypopolarization). This increases the probability of generating action potentials in the neuron.
To these, like other types of receptors, specific neurotransmitters are attached, which causes their activation and opening.
In addition to presenting an ionic channel in their structure, these receptors have a site where a specific neurotransmitter (binding site to the neurotransmitter) binds. But there are also sites of binding to other molecules, which without causing their opening modify, however, the effect of the neurotransmitter. That is, the receptors can be modulated by other molecules.
A typical example of an ionotropic receptor is the cholinergic receptor (its specific neurotransmitter is acetylcholine, ACh) of the nicotinic subtype found in the skeletal neuromuscular synapse. Part A of the scheme. When ACh binds to the receptor, the channel opens causing sodium ion (Na +) to enter, causing hypopolarization (or depolarization) at that point. The name of this type of receptors derives from the fact that they can be identified with nicotine, a substance that specifically binds to them.

Answer:</h2>
(a) 39 V
(b) 7.8 V
<h2>
Explanation:</h2>
(a) Neglecting the internal resistance of the battery, the voltage drop (V) across the battery is found from Ohm's law as follows;
V = IR -------------------------(i)
Where;
I = current through the battery
R = total resistance of the circuit.
From the question;
I = 0.75A
R = 52.0Ω
Substitute the values of I and R into equation (i)
=> V = 0.75 x 52.0
=> V = 39Volts
Therefore, the voltage drop across the battery is 39 Volts
(b) Since the set of lanterns is connected in series, then the same current flows through each of the lanterns. Also, since the lanterns are identical, the resistance () of each of them is given by the total resistance (R = 52.0Ω) divided by the number of lanterns. i.e
=
= 10.4Ω [Each lantern has a resistance of 10.4Ω]
The current flowing through them is the same as the current (I = 0.75A) flowing the circuit.
Therefore, using Ohm's law, the voltage drop ()across each load (lantern) is
= I x
= 0.75 x 10.4
= 7.8Volts
Therefore, the voltage drop across each load is 7.8 Volts

The magnitude of the average force that the ball exerts against his glove is 600 N
<h3>Further explanation</h3>
Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.
F = Force ( Newton )
m = Object's Mass ( kg )
a = Acceleration ( m )
Let us now tackle the problem !
<u>Given:</u>
mass of ball = m = 0.15 kg
initial speed of ball = u = 40 m/s
final speed of ball = v = 0 m/s
