Sarah wants to know which brand of nail polish lasts the longest without chipping. She buys 4 types of nail polish – Essie (which she normally uses,) Butter, OPI, and Sally Hansen. Every Sunday for 4 weeks she paints her nails with a different brand of polish and records how many days she lasts before she gets her first chip. She makes sure to use the same bottom coat and top coat with each type of polish, and she makes sure to do the same weekly routine each week so that her nails aren’t getting treated more roughly different weeks.
Answer:
This is an example of scientific investigation and all the elements that compose it.
Explanation:
Sarah is doing a scientific investigation regarding the nail polishes she uses. We can see this, because Sarah is using the elements that make up this type of investigation to reach a conclusion about the enamels. These elements are:
Independent variable: Element that influences the appearance of a controlled and evaluable result, such as the enamel that Sarah will use on her nails.
Dependent variable: Element that is influenced by the dependent variable and promotes the visualization of a result, such as the length of time that the enamels can remain on the nail without chipping.
Experimental group: Element that allows the study of the interaction of these variables and the result developed through it, such as Sarah's enamel marks.
Control group: Element where only the independent variable is applied. As the action of the dependent variable does not exist, the observed result is the same that would be perceived if the study was not taking place, such as the day when Sarah did not paint her nails.
Constant: Elements that are exactly the same throughout the experiment, such as the person who conducted it, the time the study will be carried out, the nail care routine and the lower and upper layers of the enamels used.
Conalan wants to answer the quesionn does phosphrus affect tomato fruit production? Which statement represents a hypothesis that he can test to answer his question
Answer:
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
Explanation:
The available options to the question are:
If phosphorus affects tomato fruit production, then tomatoes that are fertilized with phosphorus will have larger leaves.
If phosphorus affects tomato fruit production, then phosphorus should be added to the soil during planting.
If phosphorus affects tomato fruit production, then adding phosphorus to the soil will make tomatoes taste better.
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
The correct answer here would be that "If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes."
The hypothesis represents a tentative statement relevant to the research being carried out. What researchers do during the course of researching is to test the validity of hypotheses with experiments.
Since the main aim of the research is to find out if phosphorus affects tomato fruit production, the relevant hypothesis must effectively address the main aim of the research.
The production of tomato can only be measured from the yield of tomato fruits produced by the tomato plants. If phosphorus does indeed affect tomato fruit production, then the tomato plants that are supplied with the element will produce a higher yield of tomato fruit as compared to the ones without phosphorus.

"If the time period were extended to 6 hours, what would the expected blood glucose level for Person A?"
Explanation:
4 ->130
6 ->x
x=(130×6)÷4=195
In the given question, it says that If the time period were extended to 6 hours, the expected blood glucose level for Person A would be around 110-120 ml/L.
In this case, time is an independent variable whereas glucose level is the dependent variable as it depends on the time which means it changes according to the change in time.
On the basis of the given table,
there is a graph attached in which at x-axis the independent variable is represented and at the y-axis, there is the dependent variable and in respect of person, A and B graph is represented.The graph shows that that the blood glucose is dropping slowly for person A and begin to level off.on the basis of this revelation, it can be assumed that there would be a further drop of 10 to 20 units in the next two hours.

The line goes through (-2,3) and (1,-3) find the slope?
Answer:
[tex] \boxed{ \boxed{ \bold {\blue{ - 2}}}}[/tex]Explanation:
Let the points be A and B
A ( -2 , 3 ) ⇒( x₁ , y₁ )
B ( 1 , -3 )⇒( x₂ , y₂ )
Now, let's find the slope:
Slope = [tex] \sf{\frac{y2 - y1}{x2 - x1} }[/tex]
plug the values
⇒[tex] \sf{ \frac{ - 3 - 3}{1 - ( - 2)} }[/tex]
When there is a ( - ) in front of an expression in parentheses , change the sign of each term in the expression
⇒[tex] \sf{ \frac{ - 3 - 3}{1 + 2} }[/tex]
Calculate
⇒[tex] \sf{ \frac{ - 6}{3} }[/tex]
⇒[tex] \sf{ - 2}[/tex]

Prior to implementing any significant change in the use of animals, what is the most important thing that the research team must do
Answer:
obtain IACUC approval for the change.
Explanation:
The most important thing that the research team must do is to obtain IACUC approval for the change. This is because the institutional animal care and use committee (IACUC) is a requirement for any institution using animals as test subjects for their research, teachings, and/or testing. This committee focuses on making sure that the animals are not being tortured or harmed and that the testing is done correctly.

Answer:
d. adrenals; ACTH
Explanation:
The steroid hormones cortisol and corticosterone are released by the adrenals in response to the hormone ACTH( Adrenocorticotropic hormone).

common lizard → reptiles
(✿◠‿◠) hope this helps...
Answer: Hi!
These animals are reptiles:
Alligator
Crocodile
Common Lizard
Reptiles are cold - blooded animals. Their class includes snakes, lizards, crocodiles, turtles, and tortoises. They usually have dry, scaly skin, and typically lay soft-shelled eggs on land. Reptiles need to bask in the heat to keep their body temperature up. If their surroundings are cold, then their internal temperature drops.
These animals are amphibians:
Tree Frog
Salamander
Newt
Amphibians are cold blooded animals as well! They are small creatures that need water, or a moist environment, to survive. Most amphibians start off their life cycle in the water, and then transform into an animal with lungs and legs! Cool, right? The most known for this process are frogs and toads.

3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
(7 marks)
Answer:
See the answer below
Explanation:
First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:
[tex]6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2[/tex]
The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.
In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.

Which of these can be decomposed by a chemical change?
Answer:
B) CO
Explanation:
Chemical decompsition or breakdown is defined as the process in which a substance can be broken down into simpler compounds through chemical means.
CO or carbon monoxide can be decomposed by chemical change because it can be broken down into into carbon and oxygen.
While Co (cobalt), Cr (chromium), and Cu (coppoer) are present in its simplest form and can not be decomposed further.
Hence, the correct answer is "B) CO".
