'Which food did dinosaurs compete for?' would be impossible to test through observation. The last option.

<h3>What are observations?</h3>

Observation is a process of obtaining information about phenomena using any of the five senses. In other words, observations are a way of obtaining data for scientific purposes.

Why is the question about dinosaurs' food unanswerable by observations? This is basically because dinosaurs can no longer be observed in this our present world.

Dinosaurs are believed to have gone into extinction about 65 million years ago during the Cretaceous period. Thus, unless one can go back in time, there is no way to answer the question of which foods did dinosaurs compete for through observations.

Naily [24]

Bacteriophages most frequently have which sort of morphology, when bacterial genes are transmitted from one bacterium to another by a virus.

<h3>What does a bacteriophage look like morphologically?</h3>

The head is 950 x 650 in size and has a bipyramidal hexagonal form. A membrane (capsid) that is about 35 thick encloses the contents of the head.

<h3>What kind of bacteriophage is most typical?</h3>

Assphages are a large and common family of tailed bacteriophages that are thought to infect bacteria belonging to the phylum Bacteroidales. Members of this viral family have never been isolated in culture and are still poorly understood despite being present in up to 50% of people and accounting for up to 90% of human gut viromes.
