Answer:
All the statements are true
Explanation:
Viscosity is affected by temperature. For example, if we put heat over some liquids like honey and syrup, they tend to flow more freely. On the other hand, if the temperature gets cold the viscosity tends to thicken (ex: engine oil of a car during winter). These examples make the first statement true: “Viscosity increases as temperature decreases”. Viscosity is affected by pressure too. To see a change in a “molecular level”, the pressure needs to be very extreme. This make the second statement true: “Viscosity increases as molecular weight increases”. Taking in consideration both statements, we can conclude that the third statement is also correct. When viscosity is put into heat and little pressure, it tends to lessen, since the interaction between the molecules decreases and the intermolecular forces decreases. On the other hand, by default, when viscosity is put in a cold weather and pressure increases, the level of viscosity thickens, since the molecules start colliding and their motion becomes disorganized.
Answer:
The result of the test shows that;
1. This is best described as an observational study.
2. The explanatory variable is the amount of caffeine consumed.
3. The response variable is the score on the computer-based memory test.
Explanation:
An observational study draws its results from a sample to a population where the independent variable is not under the control of the researcher because of ethical concerns.
The age at which infants can typically begin to display emotional expressions is a. 6 months old.
<h3 /><h3>When do toddlers begin to show emotion?</h3>
When toddlers get to the age of 6 months, they have learnt enough about the world around them to begin to express various emotions.
These expressions are picked up from watching those around them react to various things and then they learn those expressions and repeat them.
They do not get all expressions at once however, and the rest will often keep coming as the baby keeps growing. For instance, anger comes after a year but fear will often come after the 6 month.
In conclusion, the answer is A. 6 months old.

Sheila's therapist is using <u>participant modeling.</u>
<h3><u>What is Participant Modeling?</u></h3>
A therapist or counselor can help a client learn desired or suitable actions by "modeling" (examining the conduct) and then<u> helping the client imitate the modeled behavior. </u>This approach is known as participant modeling and is employed in psychotherapy. <u>For instance</u>, if a client has to learn how to use a public transportation system, the therapist would accompany them to the bus stop, demonstrate how to wait for the bus, climb the steps, pay the driver, select a seat, and then exit the bus at the proper stop.
<h3><u>What is </u><u>
Obsessive-Compulsive Disorder (OCD)?</u></h3>
Obsessive compulsive disorder (OCD), a mental health condition that manifests as intrusive, persistent obsessions and repetitive, ritualistic behaviors, is a type of anxiety disorder. Some people with obsessive compulsive disorder claim that an unyielding urge to carry out particular rituals would help them feel better and relieve stress.

I give one, for example: when I was travelling on Malta, I found a lot of Roman remains: catacombs, mosaics, a remain of a Roman house.
Malta is an island so they must have used sea travel to get there.
