Conservation of mass states that "Mass cannot be created or destroyed". In all reactions of a closed system, mass is always conserved. So yes, the mass is conserved in this example

C. to find out if DNA carries genetic information
D. to find out if the protists evolved from the eukaryote
Answer: C. False colors are added to images to make some structures more noticeable.
False color refers to the special photography condition. This technique utilizes visible light range of the elctromagnetic spectrum to develop photograph. A false color image depicts an object in colors that differs from the actual color of the objects. This is used to capture the image of objects which cannot be detected in normal photographic techniques. It is a potent aerial photographic technique, which is used to capture large area of a region. It gives a definite color to vegetation, soil cover, river and other water body in the image.
False colors are added to images to make some structures more noticeable is the most accurate option because of the following reasons:
1. Electron microscope does not use beam of light to develop image but focuses beam of electrons to develop image.
2. Compound microscope does not use beam of electrons to develop image.
4. Electron microscope cannot be used for observation of living organisms, as high energy electron beam to develop image will be lethal for these living organisms.
Answer:
1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.
2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).
4.Establish a theory based on repeated verification of the results.
Explanation:
The scientific method is a structured approach used in scientific research. It begins with an observation, then a hypothesis is formed, and experiments are conducted to test this hypothesis. Lab results reveal whether the hypothesis was correct, needs revision, or is incorrect.
The scientific method is a systemic approach used in science to find answers to questions or solve problems. It consists of a sequence of steps, each of which plays an integral part in the research process.
The first step is to make observations about the world around us. With observations, we form a hypothesis, which is a tentative explanation for the observed phenomenon. This hypothesis becomes the basis for the experiment, where we test to see if it holds true.
The lab results are findings obtained from an experiment. They provide detailed information on whether the hypothesis stands or not. They may either support the hypothesis, totally debunk it, or partially prove it. Analyzing and interpreting these results is key in scientific research. For instance, if your hypothesis is 'All plants turn towards the sunlight,' you would study several plant species over a period of time to either support or refute this hypothesis based on the results. If some plant species consistently do not turn towards the sun, your lab results would falsify the hypothesis, leading to its revision.
