Scientific research must be guided by ethical rules.
There are four basic steps involved with the scientific method. The usual steps include observation, hypothesis, experiment, and conclusion. The steps may not always be completed in the same order.
Let's build some intuition for the scientific method by applying its steps to a practical problem from 1.everyday life.
2.Make an observation. ...
3.Ask a question. ...
4.Propose a hypothesis. ...
5.Make predictions. ...
6.Test the predictions. ...
7.Iterate.
Given parameters:
Displacement of the seagull = 145m to the east
Time taken to cover the distance = 10s
Unknown:
Velocity = ?
Solution:
Velocity is one of the physical quantities. It is the speed in a specific direction. Hence, velocity is a vector quantity having both magnitude and direction.
So, mathematically;
Velocity =
Velocity =
= 14.5m/s due east
The velocity of the seagull is 14.5m/s due east
Scant or non tonsillar exudate
slight erythema of the pharynx and tonsils
Answer:
D. Habitats are opened up for less competitive species.
Explanation:
it is generally known and approved that any increase in the complexity of habitat will cause increase in the disturbance in community diversity.after the conduction of many studies, it was conducted that the the species show variation in their abundance and distribution to habitat complexity.
