1. Knowledge of the researcher. It’s important to consider the researcher’s capacity and capability in the field which he/she wants to discover. In sense, it is in his proximity of study in order for him/her to do such approach 
2. Tool used. Making sure whatever measurement the investigator is using should be valid and reliable. Avoiding the possible results to become biased and unstable due to errors which should be avoided. 
3. Sampling method. Obtain the samples which are appropriate and that would cover the entire participants studied –not a half but the entirety of what you want to study. Entirety means as much as the possible sample covers.
4. Population. Knowing the involved participants and respondents in the study, properly defining and clustering helps the study avoid bias.

What is an observation

vagabundo [1.1K]

Hello!

Could be either:

The action or process of observing something or someone carefully or in order to gain information.

Or

A remark, statement, or comment based on something one has seen, heard, or noticed.

And in Science:

An 'observation' in the scientific sense, is when you make a measurement or evaluation of some sort. You would usually make a note of how something has changed sine the previous ovbservation. Maybe the temperature has changed: gone up one degree; or a crystal has grown: maybe it is now .1 centimeters longer.

"Observations" usually implies that you are watching some process, and either measuring or noting the change that has taken place. usually you will also want to note the time of the observation, so that you can have an idea of how quickly (or slowly) the changes are occurring.


Hope this All Helps (Hope it did)! Have A Wonderful Day! :)

Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.

Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

It would be easier to put an image instead of explaining it. Here you are!

R = Red

r = white

RR = 25% - 25% chance of red

Rr = 50% - 50% chance of pink

rr = 25% - 25% chance of white

The process of converting food molecules into ATP for cellular energy is carried out in the organelle called the mitochondria.

Snowcat [4.5K]

True

Because the energy to drive ATP synthesis in mitochondria ultimately derives from the oxidative breakdown of food molecules, the phosphorylation of ADP to form ATP that is driven by electron transport in the mitochondrion
