Alligator nests made of mud and twigs is an example of qualitative data. Thus option B is correct.
what are the different types of data ?There are different types of data which describe the things after assigning value to it, mandatory to organize, process, and present the information in a useful way is the aim of data analysis.
There are two major types of data used in research such as Qualitative data presented in words and descriptions, can only be observed harder to analyze; Examples are taste, experience, texture, or opinion
Quantitative data refers to those data which can be measured and expressed in the form of numerical value, can be measured in different units; Examples are age, rank, cost, length, weight etc.
Another data called Categorical data represents in a group form like a person responding by answering the question in a field survey.

If Chicago had experienced its average highest temperature
in August, which month would have had the longest day? Explain your
reasoning.
If Chicago had experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.
What is the effect of temperature on the length of the day?The effect of temperature induces the combination of more direct rays of the sunlight as the result of the tilting of the earth's hemisphere towards the sun to receive more solar energy and possess a warmer temperature.
But the temperature of a particular region also depends on the humidity and other abiotic parameters. So, if Chicago had experienced its average highest temperature in August, it does not mean that the longest day is in the month of August. It will remain, as usual, i.e 21 June.
Therefore, if Chicago experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.

Fritz Haber, a German chemist, discovered a way to synthesize ammonia gas (NH3) by combining hydrogen and nitrogen gases according to the following equation:
3H2(g) + N2(g) → 2NH3(g)
What volume of nitrogen is needed to produce 250.0 L of ammonia gas at STP?
L
What volume of hydrogen is needed to produce 2.50 mol NH3 at STP?
L
Answer:
Volume of nitrogen needed = 125.5 L
Volume of hydrogen needed = 84.05 L
Explanation:
Given data:
Volume of ammonia produced = 250.0 L
Volume of nitrogen needed = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Number of moles of ammonia:
PV = nRT
1 atm× 250.0 L = n × 0.0821 amt.L/mol.K × 273K
250.0 atm.L = n × 22.41 amt.L/mol
n = 250.0 atm.L /22.41 amt.L/mol
n = 11.2 mol
Now we will compare the moles of ammonia with nitrogen.
NH₃ : N₂
2 : 1
11.2 : 1/2×11.2 = 5.6 mol
Volume of nitrogen needed:
PV = nRT
1 atm× V = 5.6 mol × 0.0821 amt.L/mol.K × 273K
V = 125.5amt.L/1 atm
V = 125.5 L
2nd)
Given data:
Number of moles of ammonia produced = 2.50 mol
Volume of hydrogen needed = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of ammonia and hydrogen.
NH₃ : H₂
2 : 3
2.50 : 3/2×2.50 = 3.75 mol
Volume of hydrogen:
PV = nRT
1 atm × V = 3.75 mol × 0.0821 amt.L/mol.K × 273K
V = 84.05 amt.L/1 atm
V = 84.05 L
Which condition must be met for conduction to occur?
particles must be large
particles must be small
particles must be in contact
particles must be spread apart
The condition that must be met for conduction to occur is particles must be in contact. Therefore, the correct option is option C.
What is conduction flow of heat?A pan heats up when you place it on the flame. It's because heat is transferred from the burner to the pan. Also, it allows any other utensil or pan to heat up. Yet after a while, the vessel cools down when you remove it from the heat. That happens because the vessel's heat is dissipated onto the surrounding area.
It enables the vessel to cool. Heat is passed from a warm object towards the cold object in both situations. Typically, it occurs in every situation. Conduction is the process through which heat is transported from one object's hot end to its cool end. The condition that must be met for conduction to occur is particles must be in contact.
Therefore, the correct option is option C.

A. gas
B. solid
C. liquid

Answer:
a solid
Explanation:
because because gas would excerpt forced throughout the whole container and plasma would be too hot for the plastic container and liquid would flow throughout the container touching the sides and solid is the only one that would probably only touch the bottom of the plastic container exerting force through there

Explanation:
.) Which statement is true? (A) At a given temperature, the temperature value is a measure of the total kinetic energy of all the molecules. (B) At a given temperature, all the particles have the same amount of kinetic energy. (C) At a given temperature, the average kinetic energy of the molecules is constantly changing. (D) At a given temperature, the temperature value is a measure of the average kinetic energy of all the molecules.
Answer:
(D) At a given temperature, the temperature value is a measure of the average kinetic energy of all the molecules.
Explanation:
Kinetic energy is defined as the energy of an object due to its motion.
Kinetic energy remains the same at a constant temperature but increases with an increase in temperature.
At a given temperature, the temperature is the measure of the average kinetic energy of all the molecules. With the increase in temperature of the molecule, some of the absorbed energy is stored within the particles and some of the energy contributed to the motion of the molecules. This causes change in average kinetic energy of molecules due to an increase in temperature.
The root mean square (RMS) speed of the molecules is the square root of the average of each individual velocity squared.
Hence, the correct answer is "(D)."

it goes (in increasing order)
radio
microwave
infared
visible light
ultraviolet
xray
gamma ray
The infrared radiation in the electromagnetic spectrum is come in between ultraviolet waves and microwaves. It have high frequency than microwave and low frequency than UV rays. Thus option D is correct.
What is electromagnetic spectrum?Electromagnetic spectrum is the arrangement of different radiations in the order of increasing frequency or increasing energy thus in the decreasing order of wavelength.
The longer wave is radio waves with lowest energy and then microwave after that infrared waves are arranged in the spectrum. Thus next from visible light to UV, gamma and x-rays energy and frequency increases.
Higher wavelength radiations are less powerful but travel more distance where as shorter waves are more powerful but travel less. Thus, the radiation have less frequency than UV rays but high frequency than microwave is Infrared rays. Option D is correct.
