0.49 N
On a spring scale that measures force, a reading shows the
force of an object to be about half way between 0 N and 1 N. 0. 49 Newton is
the most accurate measurement for the force.
If we cluster the number values of 0 N to 1 N
It would be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0
N.
These numbers indicate the micro intervals of 0-1. It cannot
be the other given because the other values are either higher or lower which
exceeds the 0-1 scale. Observe.
The step of the scientific method with the information "This paper details my results on how dolphins use sonar to navigate." is: D. Report Results.
Science can be defined as a branch of intellectual and practical study that systematically observes a body of fact with respect to the structure and behavior of both living and non-living organisms in the natural world through experiments.
Some of the steps (activities or actions) that a scientist performs (carries out) while using a scientific method include the following:
- Analyze data and draw conclusions.
The results of an experiment provide the necessary data and information about the specimen which was used in the course of conducting an experiment.
Hence, a report result would convey these information to the user (reader) of scientific method proposed by a scientist.
In conclusion, a paper which details the results on how dolphins use sonar to navigate is considered a report of the results.

The amount of energy lost at the transition between each trophic level of the pyramid of energy is about 90%.
There are a total of 4 trophic levels.
The producers which bare plants represent the first trophic level. Herbivores represent the second trophic level. Carnivores represent the third trophic level. Top carnivores represent the fourth trophic level.
The 10 % rule is followed by the energy flow in a food chain. It means that moving from one trophic level to another, only 10% of energy is transferred and the rest is lost in the atmosphere.
So the 90% percent energy is lost at the transition between each trophic level of the pyramid of energy.

Explanation:
conduction- putting a metal spoon in fire
convection- boiling water. In ventilation
Radiation- suns heat reaches us by radiation. heat from fire place reaches us by radiation.
