A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.
Kinetic energy and the energy is lost when the ball is thrown.
The beauty of plants being the reason for faster blooming cannot be tested using the scientific method.
<h3>The scientific method</h3>
It is a rational order of steps through which scientific investigations are conducted.
Beauty is a relative term and can be generally subjective. What is beautiful to one person might not be beautiful to others.
If we say that the lilies bloomed first before the asters because they are more beautiful, it will be difficult to categorize beauty into a metric variable, and thus, cannot be scientifically tested.

Which type of cell might have been the first one to evolve and explain why this may have been the first.
The hypothesis that eukaryotic cells evolved from a symbiotic<span>
association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.</span>
Compare and contrast eukaryotic cells with prokaryotic cells.
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example ofprokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
