A stimulus causes a change or response in an organism. This statement is true.
What is Stimulus?A stimulus is defined as a detectable change in the physical or chemical composition of an organism's internal or external environment. It is the ability of an organism or organ to detect external stimuli so as to make an appropriate response is called sensitivity.
A stimulus can also cause an action or response which is like the ringing of the alarm clock even if we didn't sleep through it. The stimulus can include:
Irritants.Sights.Smells.Sounds.Temperature changes.A stimulus causes a change or response in an organism where the shape of a cell can tell about the job the cell is doing. Cell theory is the result of one person's hypothesis and observation.
Thus, a stimulus causes a change or response in an organism. This statement is true.

A student wants to illustrate the number of each different bird species that migrates south in winter. Which type of chart/graph would be the most appropriate to use?
a
Pie Chart
b
Bar Graph
c
Line Graph
Answers
Answer:
bar graph
Explanation:
A bar graph
You want to show that there is no connection between one species and another.
The line graph will do exactly the opposite. It will imply that the line joining 2 points gives some connection between one point and the next point.
The Pie chart is usually used to compare one number size with a another, like the total number of Covus 19 by state each state close to the other. It is not a good choice because California (for example) might have the most number of cases of the virus but it also has the largest population. You might use the pie chart by converting it to %s, but what would that give you, and how could you use it.
How do experiments show cause-and-effect relationships?

Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat
Answers
Answer:
We can write the specific heat as:
C = (dU/dT)
Where C is the specific heat, U is the internal energy and T is the temperature.
This is:
"How much does change the internal energy when the temperature changes".
Having a high specific heat (and positive) means that for every little increase in the temperature we will have a large change in the internal energy.
What does this mean?
Think in the inverse way:
A larger specific heat means that we need a large amount of heat (the heat is energy) to change a little the temperature.
Then this is good, because even when receiving a lot of heat, the body temperature will remain about the same.

Jenna took an open bowl of leftover mashed potatoes from the refrigerator and noticed a difference in smell. She determined that chemical changes occurred since the potatoes were first placed there. Which observations most likely led to Jenna’s conclusion? a change of odor a decrease in temperature a change in moisture content a decrease in mass
Answers
Answer:
its a on ed
Explanation:
The observation that most likely led to Jenna’s conclusion is a change of odor. Thus, the correct option is A.
What are Chemical changes?Chemical changes may be defined as those changes through which one chemical substance gets transformed into another chemical substance. This occurs in a variety of steps and types.
A difference in the smell of leftover mashed potatoes indicates the change in odor which is observed by Jenna.
A decrease in temperature, a change in moisture, and a decrease in mass do not make any sense with respect to difference in smell.
Therefore, the observation that most likely led to Jenna’s conclusion is a change of odor. Thus, the correct option is A.

Thank YouBy what factor (how much) does the milli- unit differ from the centi- unit?
earth science
Answers
Answer:
By a factor of 0.1.
Explanation:
Hello,
In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:
[tex]\frac{milli}{centi}= \frac{0.001}{0.01} =0.1[/tex]
It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:
[tex]\frac{centi}{milli}= \frac{0.01}{0.001} =10[/tex]

If you removed the lens from an eye and looked through it at an upright tree, how would the tree appear?
upright
upside down
the top of the tree would be pointing to the left
the top of the tree would be pointing to the right
Answers
If you removed the lens from an eye and looked through it at an upright tree, the tree appear upside down. Thus, the correct option for this question is B.
What is the function of the lens?The function of the lens in the eyes is to focus light rays onto the retina. Then the retina converts this light into electrical signals which send messages to your brain and creates the image that you observe.
The lens of the eye is the translucent biconvex structure that dangled behind the Iris of the eye. If you eliminate the lens from an eye and looked through it at an upright tree, then the perception of light is not made and cannot stimulate electrical signals by the retina, and the tree will appear upside down or an inverted image is formed.
Therefore, the tree will appear upside down, if you removed the lens from an eye and looked through it at an upright tree. Thus, the correct option for this question is B.
