A distance-time graph is graph that represents the speed of an object and the velocity of an object is its speed in a particular direction.
A velocity-time graph is a graph that represents the acceleration or velocity of an object.
A wind-velocity diagram is a diagram that measures wind<span> speed, or </span>wind flow velocity.
A HR Diagram (Hertzsprung-Russell Diagram) is<span> a scatter graph of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their spectral classifications or effective temperatures.

Answer: After the experiment in step 5
Explanation:
In a scientific investigation, first step is to formulate a question. Second step is to do background research. In third step after background research, a hypothesis is constructed. In order to test hypothesis, an experiment is designed and performed. In the fifth step, data is collected from the experiment and in the last step, conclusions are drawn from the collected data.
Neutralisation is when you have a strong acid and also a strong base (alkali) E.g 7 ph.
Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).
Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.
Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.
Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.
