Answer:
B. ∠1 ≅ ∠2; alternate interior angles theorem
Explanation:
Assume the diagram is like the one below.
The blue lines are parallel, and the red line is a transversal.
∠s 1 and 2 are between the parallel lines but on opposite sides of the transversal.
They are alternate interior angles.
Pairs of alternate interior angles are congruent.
A. is wrong. Alternate interior angles are congruent.
C. is wrong. Consecutive exterior angles are outside the parallel lines and on the same side of the transversal. They are like the two angles marked with a blue x. They are supplementary.
D is wrong. Consecutive exterior angles are supplementary.
what two factors does elastic potential energy depend upon
Answer: Spring constant k as well as the distance stretched
Explanation:
Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.

________________ substances have an equal amount of H+ and OH- ions in solution.
Answer:
Water, and other neutral
Explanation:
That means those substances have pH = 7.
When the amount of H+ is more than the amount of OH- in solution, the substance is acidic ( eg.: Lemon juice ). pH < 7
When the amount of H+ is less than the amount of OH- in solution, the substance is basic ( eg.: Baking soda ). pH > 7

Compare and contrast the dynamics of energy transfer between the Eocene Period and the Cryogenian Period. In which period would you say that Earth's system is experiencing a net gain in energy and in which period would you say that Earth's system is experiencing a net loss in energy
Answer:
The Eocene Period is experiencing net gain in energy while Cryogenian Period is experiencing a net loss in energy.
Explanation:
In Eocene Period, the population of mammals such as horses , whales and bats etc were high due to the presence of high amount of food and good atmospheric condition such as high temperature while the population of animals were low in Cryogenian Period due to the presence of very low temperature which experiencing loss of energy. Most of area of the earth consist of icy desert.

A fox spots a rabbit in a field. The fox begins to chase the rabbit, and the rabbit runs away. Which statement best describes the rabbit's behavior in response to the stimulus of being chased?
Select one:
The rabbit's behavior is a response caused by an internal stimulus.
The rabbit's behavior is a tropism.
The rabbit's behavior is a fight-or-flight response.
The rabbit's behavior is a response caused by hunger.
Answer:
C. The rabbit's behavior is a fight-or-flight response
Explanation:
The rabbit has a fight or flight response which means that when there is danger, the rabbit will either fight it or run away. In this case it ran away
The response of the rabbit in response to the fox chasing has been the fight and flight response. Thus, option C is correct.
What is a stimulus?A stimulus can be given as the physical or the chemical messenger that mediates the formation of the functional change in the body. The reaction to the stimulus has been the spontaneous reaction that can form the sudden response forming reaction.
The fox chasing the rabbit has been mediating the formation of the stimulus. The chasing act as the stimulus to the rabbit forming the rabbit to create the response or reaction of running. The reaction that forms with the stimulus of fear and frightening has been the fight and flight response.
The stimulus that has been formed arouses the fear of getting caught and works as the fight and flight response. Thus, option C is correct.

Determine the mass of hydrogen in a 2.5 sample of ammonia
show work using dimensional analysis
Answer:
[tex]\large \boxed{\text{0.44 g}}[/tex]
Explanation:
1. Calculate the molar mass of ammonia
1 N = 1 × 14.01 g = 14.01 g
3 H = 3 × 1.008 g = 3.024
TOTAL = 17.03 g
2. Calculate the mass of hydrogen
So, there are 3.024 g of H in17.03 g of NH₃.
The conversion factor is either
[tex]\dfrac{\text{3.024 g H}}{\text{17.03 g NH}_{3}} \text{ or } \dfrac{\text{17.03 g NH}_{3}}{\text{3.024 g H}}[/tex]
We want to find grams of H, so we choose the one with grams of H on top.
[tex]\text{Mass of H} = \text{2.5 g NH}_{3} \times \dfrac{\text{3.024 g H}}{\text{17.03 g NH}_{3}} = \textbf{0.44 g H}\\\\\text{The mass of H is $\large \boxed{\textbf{0.44 g}}$}[/tex]

What is the similarity between speed and vilocity
B. If the sand you ran across has a specific-heat capacity of 835 J/(kgºc),
how much energy must be added to a 2-kilogram pile of it to increase its
temperature from 40°C to 50°C? Show your work. (3 points)
Answer: 16700 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
[tex]Q=m\times c\times \Delta T[/tex]
Q = Heat absorbed = ?
m = mass of sand = 2 kg
c = heat capacity = [tex]835J/kg^0C[/tex]
Initial temperature = [tex]T_i[/tex] = [tex]40^0C[/tex]
Final temperature= [tex]T_f[/tex] = [tex]50^0C[/tex]
Change in temperature ,[tex]\Delta T=T_f-T_i=(50-40)^0C=10^0C[/tex]
Putting in the values, we get:
[tex]Q=2kg\times 835J/kg^0C\times 10^0C[/tex]
[tex]Q=16700J[/tex]
16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C

Which of the following does NOT take place in the mouth?
a)An enzyme is added to your food to help break it down.
b)The teeth mechanically break down food into smaller pieces.
c)Nutrients are absorbed into the blood stream.
d)Both mechanical & chemical digestion begin.
The breakdown of a larger molecule into a smaller molecule is called digestion. An enzyme is required for the digestion of biomolecules present in the food particles.
According to the question, the wrong option is C that is Nutrients are absorbed into the bloodstream.
Option A is correct as we stated above.
Option B is correct, the food is a mechanical breakdown to the smaller pieces by the teeth.
Option D is also correct because in the mouth both digestions took place.
Hence, the correct option to the question is C
