A bacterium, because it is contagious -1
A fungus, because it infects livestock -2

Answer: See explanation
Explanation:
a. A social psychologist spends the afternoon at the mall and unobtrusively records how teenagers act in groups.
This is an observation. This is because the social psychologist is gathering data about the behavior of the teenagers and recording it.
b. A positive psychologist measures the relationship between spirituality and happiness.
This is a correlational study as the relationship between two variables are being measured.
c. A health psychologist randomly assigns people to meditate in the morning, at night, or not at all. After eight weeks, people rate their overall moods.
This is an experiment. Here, the independent variable is manipulated and its effect is tested on the dependent variable.
d. A cognitive psychologist sends out a questionnaire to all incoming students to determine their computer skills.
This is a self-report survey. A survey is referred to as a self-report that is used for research purposes as information regarding people are collected.
Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
diameter of 10 cm in the box. Susan puts 1,000 1-cm glass marbles in her box.
1. Whose box has more empty space? Explain.
Answer:
Both boxes have the same amount of empty space
Explanation:
Given
Cube Box
[tex]Length = 10cm[/tex]
Robert:
1 glass marble
[tex]Diameter = 10cm[/tex]
Susan:
1000 glass marble
[tex]Diameter = 1cm[/tex]
Required
Whose box has more empty space?
First, we need to calculate the volume of the cubic box.
[tex]Volume = Length^3[/tex]
Substitute 10cm for Length
[tex]Volume = 10^3[/tex]
[tex]Volume = 1000cm^3[/tex]
Next, calculate the volume of Robert's glass
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 10cm[/tex] --- Given
Substitute 10 for diameter
[tex]r = \frac{1}{2} * 10cm[/tex]
[tex]r = 5cm[/tex]
So:
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 125[/tex]
[tex]Volume = 523.8cm^3[/tex]
Next, we determine the volume of Susan's 1000 glasses
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 1cm[/tex] --- Given
Substitute 1cm for diameter
[tex]r = \frac{1}{2} * 1cm[/tex]
[tex]r = 0.5cm[/tex]
Substitute 0.5cm for radius in [tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.125[/tex]
[tex]Volume = 0.5238[/tex]
But there are 1000 glasses.
So, the volume of 1000 glasses is:
[tex]Volume = 0.5238 * 1000[/tex]
[tex]Volume = 523.8cm^3[/tex]
--------------------------------------------------------------------------------------------------------------
For Robert:
[tex]Volume = 523.8cm^3[/tex]
For Susan:
[tex]Volume = 523.8cm^3[/tex]
Since, they have the same volume.
Both boxes have the same amount of empty space
From the dimensions of glass marble for robert and susan, we can say that; none of the given boxes have more empty space.
We are told that the cubic boxes have a measure of 10 cm for its' sides.
Formula for volume of a cube is;
V = lwh
where;
l is length
w is width
h is height
Thus; V = 10 × 10 × 10
V = 1000 cm³
For Robert;
We are told that he puts a glass marble with a diameter of 10 cm in the box. The glass is usually spherical in shape and the volume of a sphere is;
V = ⁴/₃πr³
Thus;
V_rob = ⁴/₃π × (10/2)³
V_rob = 523.6 cm³
Volume left for rob = 1000 - 523.6
Volume of empty space left for rob = 476.4 cm³
For Susan;
V = ⁴/₃πr³
Thus;
V_sus = ⁴/₃π × (1/2)³ × 1000
V_sus = 523.6 cm³
Volume left for susan = 1000 - 523.6
Volume of empty space left for susan = 476.4 cm³

Why are water striders able to "walk on water"?
Answer:
Water striders can walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and large hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.
