a plant.
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
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
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.
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.
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.
an unknown. eg x+1=3 means something plus 1=3. the unknown, or 'something' must be 2. therefore x=2
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.
A protist is an "animal" like type of diatom. an aglage, is the "plant" like diatom. The protist must find its own food, while the agage makes it's 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.
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.
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?
Chloroplasts. They are little things found only in plant cells which help them photosynthesise. In order to photosynthesise you must has chloroplasts.
They should have pigments and enzymes. They are in chloroplasts
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.
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.
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
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.
