Answer:
False
Explanation:
In a controlled experiment, you will only test 1 variable at a time. The independent variable or variable that is changed will be tested by the experimental group. The control group is left alone, so the scientist can compare the results to that group.
The experimental group is the group that is left alone during the experiment is statement is false. Thus, the option (b) is correct.
What is experiment?
The scientific process of study is referred to as an experiment. Research into substance and theory is the foundation of the experiment. The experiment's goal is to validate the phenomenon's and observational assumptions. The experiment is a variable and a hypothesis. The comparison and answer to the query are the two components of the experiment.
Based on independent variables, the experimental group. The experiment test is conducted just once. In the experimental group, the independent variables are altered. Data variables are outcomes that react to dependent factors. In order to compare the findings to the control group, the scientist leaves that group alone.
Therefore, option (b) is the correct.

What is the domain of the given function?
{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}
{x | x = –4, –1, 3, 5, 6}
{y | y = –2, 0, 1, 4, 9}
{x | x = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}
{y | y = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}
Answer:
Choice A is correct. This is because of the fact that the domain means the x-values of a function. The x-values given here are 3, 6, -1, 5, & -4. When you rearrange these in ascending order, you will get -4, -1, 3, 5, & 6. The meaning of the symbol "|" is "such that". When you put our domain in set notation, we will get {x | x = -4,-1,3,5,6}, which means "x such that x is equal to -4, -1, 3, 5, and 6". Hope this helped :)

Explanation:
Using complete sentences, briefly describe what the image above represents. What are the main differences between the tierra caliente level and the tierra fria level?
The image represents the various classification of Earth's environment based on the altitude. To each zone correspond a certain type of climate, where certain types of plants for example can or cannot grow. That's called "Altitudinal zonation". Basically, the higher you go, the colder it gets. That's especially useful to describe the climate in tropical but mountainous regions, like Latin America.
Difference between tierra caliente and tierra fria:
Tierra caliente (warm land) level is the lowest and goes from sea level up to 2,000 or 3,000 feet depending on who you ask, and it's the perfect for fruits and most livestock for example.
Tierra fria (cold land) level starts at 6,000 feet. It's a zone where virtually no livestock can be found and only robust vegetables (like potatoes) can grow easily.
The main differences are of course their altitude but also, as a consequence of the altitude, the types of plants that can grow in each level, which are extremely different.

PLEASE HELP!! WILL GIVE 30 POINTS AND MARK BRAINLIEST!! How has Sudan's history helped shaped its geography??
How have the earth’s continents moved over time? What is some evidence?
Answer:
Here hope it helps good luck
Explanation:
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics. The rock formations of eastern North America, Western Europe, and northwestern Africa were later found to have a common origin, and they overlapped in time with the presence of Gondwanaland. Together, these discoveries supported the existence of Pangea. Modern geology has shown that Pangea did actually exist.
Evidence for the movement of continents on tectonic plates is now extensive. Similar plant and animal fossils are found around the shores of different continents, suggesting that they were once joined.
Which Crosscutting Concept BEST describes the following statement "Observing the repeating moon phases." Patterns Cause and Effect O Energy and Pattem O Stability and Change
Answer:
Stability and Change
Explanation:
Cross-cutting concepts in science show the application in different domains of science.
The cross-cutting concept of the given statement shows "stability and change". Stability refers to the system that experiences a small disturbance but returns to its stable state after some time.
The cyclic pattern of changing moon phases refers to stability and change as changes happen in the system but it come to its original state again.
Hence, the correct option is "Stability and Change".

Why might native Americans living today be uncomfortable with Columbus Day as it has been celebrated through most of the 20th century?
Answer:
Columbus was a horrible man that killed, enslaved, tortured and raped Natice Americans when they did nothing to him besides welcomed him onto their land with open arms. He forced his believes onto Native Americans and brought deadly diseases that killed the majority of the Native population. A day that is "celebrated" because he "found" America (although he didn't) despite the awful things he did would be upsetting knowing that person is the reason millions had died.

Explain in three or more sentences how you use the following items and explain what life will be like if we no longer had access to these items:
1. 12-month calendar
2. The number system (the ability to use 60 seconds and 60 minutes to tell time)
3. Wheels (for transportation)
Answer:
1. Without a calendar we could not know when to celebrate any of the festivals on particular days. We would even get the days of the week confused after a while. We would not be able to tell when a year had gone by, so it would be hard to keep track of someone's age.
2. Without numbers we wouldn't be able to count or measure anything. We would forget our age one day, and possibly forget how to count. Also we wouldn't be able to tell time, unless we used the sun. It would make life very problematic.
3. It would take very long to get us somewhere. We could no longer travel with airplanes, since they use wheels to take off. Such a simple thing as going to the grocery store, would turn into a huge task. Traveling would take very long to do, or might be non-existent if we didn't use horses.

Describe how the sea erodes the coast (3 marks)
Answer:
There are three main ways in which the coast can be eroded by the sea:
Hydraulic action: lots of sea water crashes against the land, causing air and water to become trapped and compressed in surface cracks. When the sea retreats the air expands, weakening the cracks in the rock and causing pieces of the rock to break off.
Corrasion: caused by bits of rock hitting the cliffs and other parts of the land, causing more bits of rock to break off.
Corrosion: involves the chemical action of sea on rock, often happens with limestone beaches, when the limestone dissolves in the sea water although the salt can affect some other stones as well.
Explanation:
Answer:
Waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the sea takes lots of energy from the power of destructive waves. Transportation - the movement of eroded material up and down, and along the coast.

ASAP PLEASE SOMEONE HELP ME: The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK:KL:LMJK:KL:LM is equal to 1:6:1.1:6:1. If JM=32,JM=32, find KL.KL.
Answer:
answer is 24 i put 28 in and it was wrong.
Explanation:
When JM=32, KL will be 24. Check more about line segment below.
What are line segments?A line segment is known to be an aspect of a line that has two end areas and also has length that is finite.
Note that when points J, K, L and M all lie on the same line segment, it is equal to 1:6:1.
If the total line segment is =32
JK:KL:LM = 1 + 6 + 1 = 8
lndividual (One unit) line segment = 32/8
So one unit = 4
Note that JK = 6
So KL = 6 x 4
= 24.
Therefore , the answer is = 24
