B is correct
D is appealing but the electrons spend more time around the oxygen than the hydrogen
Answer:
The correct answer would be d) summarized data.
The summarized data gives the quick and easy description of all the observations obtained in the experiment.
The data can be summarized using different categories such as the total of the observations, frequency of the observations, mean value, variation et cetera.
It helps in deducing any conclusion from the observations such as the pattern of increase or decrease in the biological activity.
Answer:
the volume increases in amplitude of the sound wave. Pitch is seen as a change in the frequency
Explanation:
is this what you were asking for?
DNA, is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional.
RNA, helps carry out this blueprint's guidelines.
The main type of evidence the scientists used is fossils.
Palaeontologists study plants and animals that existed in the geologic past. To do so, they use fossils and try to determine an organism's evolution and relationship with the environment and other organisms. In this example, palaeontologists used fossils from ancient horses that have gone extinct and try to decipher their evolutionary path. Recognising the evolutionary steps of the ancient horses will make it possible to compare them to the modern horses.
