Answer:
A
Explanation:
Protons are positively charged so A is right
We know the rest are wrong because neutrons have no charge and electrons are negatively charged.
Answer:
The answer is A.
Explanation:
Lets look at the charges of each part and see which one lines up.
A) The protons in an atom have a positive charge.
B) The nucleus contains the protons and neutrons. Since the neutrons have no charge and the protons have a positive charge, the overall charge of the nucleus is positive.
C) Electrons have a negative charge.
D) The neutrons have a neutral charge meaning they do not have a positive or negative charge.
The only answer that lines up with the choices is A.

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.

Which most accurately describes the basis of the scientific method? A.) a path of clearly defined steps that must be followed in a particular order B.) a possible answer to a scientific question based on knowledge or research C.) the recipe for how to conduct an experiment that must be followed precisely D.) the process of hypothesis and testing through which scientific inquiry occurs
Answers
The statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.
The scientific method is a series of sequential steps used to build scientific knowledge.The steps of the scientific method include:
To make observations about a given phenomenon of the natural world and formulate questions based on these observations.To pose a plausible explanation (i.e., a hypothesis) in order to answer these questions.To test the working hypothesis by experimental and/or observational procedures.To collect data in order to confirm or reject the working hypothesis.Examine results and draw conclusions.In conclusion, the statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.

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]

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.

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.

Nicholas has been biting his nails since he was a kid. He wants to break the habit so he puts bitter-tasting nail polish on his left hand and leaves his right hand without polish. After 3 days he notices his nails on his left hand have grown but he continued to bite his right-hand nails.
A. Independent Variable=
B. Dependent Variable=
C. Control=
Answers
Answer:
Independent: Putting the nail polish
Dependent: nail growth
Control: right hand, without polish
The experiments are known to have various variables. In Nicholas's case, nail polish is an independent variable, nail growth is a dependent, and right nails without polish are a control.
What are independent variables?Independent variables are defined as the test variables that in an experiment are not constant but are kept varied and manipulative causing various effects on the result of the hypothesis. Putting the bitter nail polish on the nails of the left hand is a test variable.
The dependent variable (outcome variables) along with independent results in cause and effect and are conditional on the independent factors. The length of nails is dependent as it is affected by the nail-biting.
On the other hand, the control variables are constant in that the factors are limited so that they do not interfere with other factors that affect the outcome. Fingernails on the right hand with no polish are controlled.
Therefore, nail polish is an independent variable.

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.
