What else can I help you with?
To eliminate the possibility of hidden or unknown variables the scientist must run what kind of experiment?
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
What measurements must be unknown in order to find density of a substance?
There are multiple definitions for density depending on the precise science or engineering application. However, density typical is the ratio of mass to volume. Therefore, you must know both mass and volume to calculate density.Density = mass/volumefor exampleD=M/VD= 120g/40mLD= 3 g/mL
Why do scientists repeat experiments?
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.
What are the different types of jigs?
I'm not entirely sure, but I do know that there is a dowelling jig which is used for putting dowels in a product. Therefore there must be other types of jigs for different functions.
Why is HCl added before titration?
Without the specific details, one cannot be sure, but this is probably a back titration. You add a known amount of acid to your unknown, then titrate to measure how much has not reacted. You can then calculate how much of your first chemical must have been present.
What does x stand for in an equation?
an unknown. eg x+1=3 means something plus 1=3. the unknown, or 'something' must be 2. therefore x=2
When 4 is subtraced from one half of an unknown number it is equal to 6 the number is?
Simply reverse the question and you find that 4 + 6, which is 10 equals half of the unknown number. 10 x 2 = 20, which must therefore be the unknown number.
What is a protist that cant make its own food?
A protist that can't make its own food is a heterotrophic protist. These protists must obtain their nutrients by consuming organic matter from their environment, such as other organisms or organic debris. Examples include amoebas, paramecia, and plasmodium.
What is the smallest unknown prime number?
If it is unknown, how are we supposed to know it? There must be a least unknown prime, so the next prime below that must (?) be known, sap pk. The next prime, pk+1 , must be the least unknown prime - so what is it, approximately?
How do you find the missing values or expression?
In every formula, there are numbers and unknown values. What has to be done is to perform the calculation by removing the known value and leaving the unknown. For instance; x+3=5. In this case, one has two values that must be removed to discover the unknown value. So one has to perform the inversion of the formula to solve for the unknown quantity. Therefore, we "flip" the equation. Since X is the unknown, we must use what we have. Therefore we subtract (doing the inverse of the stated equation) 3 from the total of 5. The sum of the answer will give the unknown quantity, in this case 2. To prove that you are right, you "plug in" the value that you have solved for into the missing value space and perform the equation to see if the answer is correct.
What must a plant have and get for photosynthesis to take place?
They should have pigments and enzymes. They are in chloroplasts
Why must plant cells have both mitochondria and chloroplasts?
Plants need both mitochondria and chloroplasts to maintain a healthy plant. The mitochondria power the plant when the chlorophyll is stunted by lack of sunlight.
Why is the dragonfly in animalia'?
There are 5 kingdoms; Fungi, Plants, Animals (Animalia), Bacteria (Monera), and Single-celled organisms (Protists). So I think that it's pretty obvious that a dragonfly is not a plant, bacteria, protist, or a fungi. So therefore using the process of elimination it must be a animal.
What must cells contain in order to perform photosynthesis?
Cells must contain chloroplasts, which are organelles that contain chlorophyll, in order to perform photosynthesis.
To eliminate the possibility of hidden or unknown variables the scientist must run what kind of experiment?
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
What are two things from the environment that chloroplasts must have to make food?
Chloroplasts require sunlight and carbon dioxide from the environment to carry out photosynthesis, a process that produces food for the plant in the form of glucose.
Can chloroplasts make Glucose at night?
Chloroplasts must capture the sunlight during the day and make it into Glucose, STARCH, or store it in the mitochondria as ATP energy. After this happens they will then rely on the mitochondria for glucose at night. Either way, the plant must have energy at all times. Hence why it is stored in the mitochondria.
